When emilias first trial aired on TV Tappei tweeted out that Emilias mother is human and Emilias father is a full elf. So there isn’t any half elf + half elf shenanigans. This has been confirmed by Tappei.

"If you wonder why i have Pandora in the thumbmail , it's because you can't talk about the re zero theory iceberg without including pandora".

Minerva after the anime episode and the light novel we can say like 80% now.

It would explain Minerva refusal to meet Emilia in her trial

I feel like puck was fortuna's brother. Think about it , puck says that he is a father to emilia and also calls emilia his daugther. Puck also mention that he once had a "handsome face" and that he wasn't always like this. Its just a theory.

It's implied that Emilia is special and was born to do something important Everyone in her village kept her hidden or regarded her as a goddes In the WN one says that "the word is waiting for her" and puck says "she was born to be happy" And the witches seem to know something but hide it from Emilia

This took long to make, hope you enjoy it. Feel free to like and sub if you want more re: zero content. =)

I just hope the father isn't time traveling Subaru.

I'm guessing you haven't read Volume 15 cuz in the Tea Party after the third trial when Emilia met Minerva, she at first was afraid because of her Witch Presence, but when Minerva screamed at her to go forward, Emilia felt a Warm Feeling of Nostalgia. Also, Minerva talked like she knew Fortuna.

that would explain her tsundere traits

welp, i got the vibes with how similar emilia's mother dressed like minerva. So i think it's her

Isn't obvious? It's Petra. They both: -Want to smash Subaru. -Act adorable. -.......... IRREFUTABLE PROOF!

7:20 If they wanted to go the Satella route, it could be revealed that Emilia's father is Fortuna's half-brother. Two precisely 50% half-elves would have a precisely 50% half-elf child.

Who is here after watching Re:Zero kara Hajimeru Isekai Seikatsu 2nd Season Part 2 Episode 10?

Remember how Beatrice was waiting for 400 years for "the one" that never existed? Puck could easily be searching for Emilia before she was even born. It was also mentioned that Puck has lost some of his memories when he made a contract with Emilia. Also lets not forget that Echidna detests both Emilia and Satella (for whatever reason). So her calling her witch spawn might only relate to Emilia's looks. Besides, she comments on Emilia's traits like some jealous bitch even though they meet for the first time. Apparently Echidna doesn't care who Emilia is, and just vents her frustration on her.

Considering it feels too obvious for it to be Satella, I think there is a strong chance Minerva is Emilia’s mother. I don’t know how, but if Minerva’s remains are in the seal, it would make sense given that Emilia’s father and Fortuna were protecting it. We also have to remember that the seal is otherworldly, so it could, very possibly warp time in some sense, or could possibly be a gate to Echidna’s world. The latter could actually make some sense given that Pandora wants to open it. (Note: End of the World doesn’t necessarily imply directly Satella, but instead could imply the destructive power of ALL the witches).

I am still gonna bet that Echinda is her mom. Like you said, if all the Echinda(s) are different from each other then, the Echinda in the trial that said she knows Emilia's mom was more likely referring to the original Echinda. We know original Echinda cares about half breeds since it was one of the reasons why she constructed the Sanctuary. Also we know original Echinda has a history of trying to help humanity and failing to reach a conclusion that saves all. It would make sense Echinda in the trial would hate her other "self" for the path she took to the end. Emilia also has that "I want to save others and bring equality to all races" thing going on for her.

Also, if Minerva is Emilia's mother, its quite possible that Puck is her father. Puck could be an elf back then, who failed to watch over his own daughter, and so he asks Echidna if she would allow him to watch over her, even from a distance. Puck is also 400 years old or more, which means he was there when Emilia was born, according to this theory. This would explain why when Emilia unfroze, his first line was "I'm sorry I left you alone" and why he hesitated to say his name when Emilia asked him, and also why he's so protective of her

Something I just realized while doing a rewatch of Season 2, her mother HAS to be human. The reason why is because of our knowledge of the Sanctuary and Frederica. Remember, Frederica is a quarter-blood beast-human, while Garfiel was a half-blood. Frederica could leave the Sanctuary because she wasn’t a full half-blood, but Garfiel can’t. Emilia, on the other hand, can’t leave the sanctuary because she is a “full half-blood” per the fact that she passed out once they crossed the barrier. Given that we know her father is an elf, then her mother HAS to be a human and not a half-elf. If her mother was a half-elf, like we were initially led on to believe, then she wouldn’t be confined to the barriers of the Sanctuary in Arc 4. Now, something else I would like to note. After having done some research, I don’t think Minerva is Emilia’s mother anymore, but she is definitely related to her. By that, I mean she may be her Aunt. After Minerva died, there is a chance that her witch factor was given to her sister. In turn, that would make her sister a witch, and possibly the mother of Emilia. In turn, that truly does make Emilia the daughter of a witch. Remember, Tappei does have a way of giving us red herrings, and Minerva being Emilia’s mother might be one of them. But Howard, that still doesn’t answer the fact that Minerva died 400 years ago, over 280 years before Emilia. And you would be correct, but we must remember Pandora has a way to manipulate our memories and perception of time. Additionally, there is the whole door in the forest that we don’t have answers to. Something tells me that the answer behind that door is strongly related to Emilia’s mother. How Tappei can connect those dots is beyond me, but I think it is closer to reality than what our current guesses are so far.

Fun fact, in RPG, a Half Elf is one which don't have full Elf lineage. So a quarter or a 3-quarter is still considered as a Half Elf. Also, genetic can be quite funny: a Half Elf and an Elf can technically give birth to a full Elf as well as a Half Elf (and everything in between).

Can you please make a a summary for the conversation between Minerva and Emilia? I have a feeling it would be interesting to read In the web novel Emilia was confused why Sekhmet was the one talking to her instead of echidna Sekhmet told her why each other witch wasn't a good idea even though she'd rather rest Echidna was mad and didn't want to talk to Emilia, Typhon and Daphne couldn't keep up a normal conversation, carmila was shy or nervous and Minerva would get emotional and say things that she shouldn't

How...? How the hell do you push these out so fast and with such great quality? Just please don't burn yourself out man...

my theory was because -Echidna was creating puck exclusively to protect Emilia or if he can't, Puck order to destroy the world instead. even if she hate Emilia, she was still one of her bestfriend daughter and legacy. -Puck said to Emilia not to look at her face, probably by the order of Echidna maybe or it can also because if puck was indeed Emilia's Father. -Echidna and Minerva created a promise not to tell Emilia anything about Emilia's Mother. -by Fortuna statement, white haired and purple eyes supposed to be run within the family and her mother supposed to be human and not have white haired or purple eyes. so Satella maybe just another family member. if Minerva was Emilia's mom, it will explain why Minerva was a good friend as well because they are family. -Emilia first seeing her face after a while in the trial after Echidna disappear and it will be trouble if somehow she seeing Minerva faces. changing in the LN probably to make their relation much more impact and throwing little bit of clue. -Elior Forest Seal can be open by 2 person. 1 was Emilia and other was maybe echidna probably requirement maybe was because they are witches daughter. Echidna also claim know nothing about the door. also reason why hector hunting her. -Echidna hate Emilia probably because of her birth as witches daughter leading to Minerva's death. elves suicide squad probably also being ordered by Pandora and happen at the same time as hector vs Echidna. -Minerva killed by Envy, and Echidna probably died trying to seek revenge to Satella and Envy. -Reason why Minerva being trapped by the elves probably because of Pandora as well the same as Echidna with Hector. they cornered Minerva to obtain newborn Emilia. i kinda thinking, so far we know there is 3 Echidna in the series. 1 and 2 was real Echidna sealed and sanctuary, the other one was anastasia spirit scarf. make me think Tappei making so much echidna to dodge this question.

Puck really needs to comeback, we need answers damn it.

Plot Twist: She's SHIZUKA JOESTAR

In the anime.Echidna stated that she is a virgin. (S2/EP8). +When Emilia met minerva in season 2, Minerva cried when emilia stated that fortuna is her real mother.

This could also explain Echidna's rather hostile way of talking to Emilia while still creating a powerful allie to keep her safe in puck and helping her grow from her past. It seems so weird she would be so helpful yet hostile to the girl...unless ofcourse her mother have to be someone she cared about, I believe Echidna blames Emilia for her friend's death. Minerva died because she wanted to save the elfs most likely because her child was there and Echidna just can't get past the pain of losing her friend and are choosing to blame Emilia. It would explain a lot of her interactions with Emilia. The reason she scolds her for being such a bad child is because she finds it annoying to see the child that in her eyes killed her friend be such a brat. She cries when she sees Emilia's greatest wish because she hates how Minerva gets completly replaced by Fortuna and it pains her to see that the one that her friend gave her life to doesn't even know it and thereby doesnt appreciate it.

Its definitely Minerva.

I think Minerva is the most sensible answer when it's looked at this way, but I still think Emilia is a clone of Satella created by Echidna, so her biological mother would be whoever Satella's mother was, but depending on how it is looked at by different people, Echidna could be seen as her mother for creating her (much as she is Beatrice's mother), or Satella could be seen as her mother for being the person she is a clone of. This means that when different characters talk about her mother, they may not actually be referring to the same person... But, yeah, if I'm way off with my crack Emilia theory then it's probably Minerva! Nice vid as always!

Apparently you've never seen Emilia vs Eminem rap battles. Not only can she carry a tune , she carrys it 48 beats per second.

"Is Carmilla a bitch?" Dang what a question lmao I laughed real hard when I saw that

What I think is that Minerva is Emelia's mom and also Satella's mom bc roswal says that Emelia shares a lineage with the witch of envy but never says that she is her mother so that means she is related somehow so the most logical option would be a twin sister or an older sister and Sattella wouldn't b her mom bc she's also a half elf which also supports my theory bc Satella and Emelia are both half elves

Minerva (at least in the Anime) also doesn't want Emilia to see her, maybe because Emilia would've noticed that she is her Mother. That leaves one Question open, who is Satella and why does she look exactly like Emilia. Maybe Emilia had/has a Sister which is Satella.

Hey man keep up the great videos

I was always dubious of Emilia being 100 The number 400 years crops up so bloody often , but never 100

Doesn't reading someone's book of the dead show the persons entire life? He read Minerva's disn't he? If so, wouldn't he have seen that Minerva gave birth to Emilia then? If he did see that then why wouldn't he at least bring it up in his mind? It's like he never once saw it. I guess the books don't show the entire life then.

Some of the argument is kinda dumb to be honest. How does Emilia inherits non tangible characteristics from a mother that was never there to even display said quirks for Emilia to learn from to begin with. Such as tone-deafness. Anime logic is the answer is it

"Is Carmilla a bitch?" Bruh lmao

I think she is Echidnas sister, it’s highly likely that Echidnas mom was a witch, they’re are a lot of similarities between Emilia and echidna mainly that they both have silver hair

Puck says he was "wandering for three centuries" he doesn't say he was searcing for Emilia during all that time, merely that he ceased wandering once he found Emilia. It is possible that he wasn't searching for her at all, and found her by sheer accident, but once he did he decided to stay with her. Of course it is also possible Echidna instructed him to find her, even before Emilia was born since Echidna had ways of fortelling future events and a habit of giving open ended instructions like this to her spirits. Possibly even that Puck was instructed to find her some time into his wanderings, through an event, a gospel/tome of wisdom, or a meeting with someone who had access to one. The fact is that Tappei has deliberatly not told us about how and why Puck found her, so that's probably an important spoiler for something he has planned further down the line. Either way I'm inclinded to belive that the Emilia is 100 odd, not 400 odd years old. If she were 400 odd years old then the witches cult might not even have existed during her infant years - yet they play a prominent part in Emilia's young life with the attack on the forest, the downfall of Juice and it just doesn't feel to me like these events were happening immediatly following the sealing of the witch of envy/death of the other witches. One thing to consider when trying to work out who Emilia's parents are, is that she is a Royal candidate. Exactly how is one qualified to become a royal candidate, is it royal blood? Seems so in Felt's case. It may also be the case with Priscilla and Krusch who both come from old noble families which might have some shared lineage with the Lugunican line as in a feudal system its common for lesser royals to marry into other royal families as political ties and into prominent noble families to reinforce loyalty. Not sure about Anastasia or Emilia but its not impossible that they have royal blood. Ultimatley we dont know enough about the selection of the candidates to be sure, but i think it's an interesting theory that they all may have a shared lineage to at least some extent

Hold up. So Emilia was froze at age 15 for 100 years, making her 115, but then she was physically age up 3 to 4 years so that makes her biologically 18 or 19, even though she has the mentality of a 15/16 year old. Wicked.

What happened in the scene in which minerva and emilia spoke with each other after the trials ? I read the webnovels.

tbh i think emilia is a clone.

i'm your like number 1000! Hell Yeah, great video by the way.

Huh I think you’re right. My theory is that Satella couldn’t have been Emilia’s mother but maybe a relative. You see thanks to Fortuna appearance, we can tell Emilia inherited her looks (silver hair, purple with blue dot eyes) from her father side. As we can see no elves seemed to possess those traits other than Emilia’s family, so wouldn’t it be weird for her mother to have traits of her husband family?

I still hold to the theory that Emilia in some form is Satella - like the “sealing away” of Satella sealed her soul away and her body was granted a new soul or something like that which became Emilia. I would be interested to see you do a theory video on “Is Emilia actually Satella?”

On the puck thing, what if Echidna told puck to look for Emilia because a book of wisdom said that he needs to?

I’d like to point out that usually in fictions 3/4 elf are considered half elf, or to be more precise, half elf is the group of humanoids that share an elven Bloodline without it being 100% pure. This means that Satella is not out of the picture yet

After today’s episode I can see it

Now idk if the anime will adapt the end of the trials with Sekhmet or Minerva (hoping for minerva tbh, best girl combo will always be pleasant to watch).

From what i know in the light novel arc 4,Emilia's white hair gene is inherited from her father,but from what we know in the anime,Satella's hair is white, I think it's related to Emilia but not her mother

Daily uplaods are fire i love tuning in.

*What about how Minerva made Emilia keep her head forward, and then ended up crying. And hugging her while apologizing after the third trial in the witches tea party?*

Holy shit i see now...think about it puck is a spirit made by Echidna. Puck was looking for Emilia before she was born ...Echidna is able to predict the future...puck literally calls Emilia his daughter. What if puck was made using Emilia fathers spirit cause I always thought it was weird how puck and Betty act differently ummm only need to figure out why Echidna hates Emilia but at the end of Emilia trail Echidna was crying her eyes out wile saying she hates her...and why does Emilia look exactly like satella.?.but I'm sure now Emilias mother is Echidna

Feel like we’re going to learn in arc 7 how rem can smell witches blood

Yessir keep up those videos my guy

I want to say It is biologically possible that Satella is her mother (not that I believe she is). If Emilia's father was a half elf (therefore half brother of Fortuna), then it is possible that Satella and her father could have a half elf girl. It is possible but would be unlikely that if her both parents were to be half elves with silver hair and amethyst eyes. Then they would look like related.

I've red WN but didn't know that in LN its Minerva that speaks to Emilia is there much different dialog ? Besides, If Emilia is Minerva daughter and Echidna is on best terms with Minerva, than why is Echidna so mean to her daughter like she cant stand her?

If Mineva is really Emilia's mother that could mean she's a Lugunican Princess and makes me wonder if Beatrice is an artificial spirit based on Minerva. Look how Beatrice has a little crown on her head like the Lugunica Royalty. I wonder since Puck is based a humanoid, (perhaps Emilia's dad) and notice how Beatrice loves Puck a lot. Oh, and also, like Minerva, Beatrice hates people dying before her eyes, see how she helps the people from dying after the fight between Sirius(wrath) and Regulus(greed).

Ik we dont know have info regarding lia"s mom But I have theory on emilia parents For this theory I an going to consider 1) juice calling Emilia as emilia sama ,sometimes Fortuna call lia as little princess. 2) witch cult have some sort of connection with elf clan 3) juice mentioned ' church ' 3) pandora is behind Emilia parent death 4) while i saw one clip in isekai quadrent I saw one word 'arch priestess ' So here my theory If sin arch-bishop exists then sin arch-priestess may also exists of that certain church. Also from what I know there are cardinal members may also exist So my conclusion is 1) emilia mom is either arch priestess or cardinal member of witchcult 2) emilia father is head of elves

emilia is tone deaf???? sad stay alive noises

This is just a theory but do you all think echidna and emilia are sisters because they both have similarities and their names both start with a E and ends with a A. 😃😃😃

Satella can't be Emilia's mum because Satella is Emilia in the future (using Envy's time manipulation).

I think that emilia's mother was a normal witch who met echidna and had a great friendship with her as sisters, and if you notice by the fortune emilia pulled the characteristics of her eyes and hair color the same then emilia pulled these characteristics of her father since they are brothers, the face and personality of the mother, since echidna says that Emilia is foolish as her mother.

I'm glad to see you've been reading people's comments! Great video!

It's Minerva. That just makes to much sense with what is shown. Further, with what it learned in Arc 5 about the Artificial Spirit Echidna, I believe Puck is the Artificial Spirit Minerva. As for Emilia being hundreds of years older than stated... No. The logic used to claim that is false. Just because Puck was looking for her for so long does not mean he was specifically looking for her. He could have been tasked with finding someone who fits Emilia's description. But... I do realize, that even then timing does not make sense. The witches including Minerva died like 400 years ago. So Emilia would have to be born then if she was Minerva's daughter. But she was clearly a kid 100 years ago, so... how does that make sense? It does not, as we are still missing a piece of the puzzle. I think Emilia is Satella, and part of the Envy Authority is time travel. She was born, and accessing and losing control of her power, traveled 300 years into the then future. Possibly bringing the entire Elior forest elves with her, as it was suggested they were displaced in some way. Later... Emilia's psychy fractures and splits into Satella and Witch of Envy, before traveling back to 400 years ago.

I still standby satella being her mom I interpret half-elf /half-giant, half-anything as a combination not a specific ratio. also tone deaf isn't a genetic trait or anything I personally am tone deaf I can't sing for sh*t but my sister is in some big choir at the same time neither of my parents are neither good singers or bad

I’ve got a good theory, what if the witch of envy is Emilia’s mother (not Satella cause the witch of envy and satella are 2 different beings sharing the same body) even though she looks like a half elf but let’s not forgot the witch of envy was absorbed by satella or to be more accurate the envy factor wasn’t compatible with satella which broke her mentality to 2 different beings one being the witch and the other being satella.To be more honest Minerva being the mother makes more sense than this

I have a suggestion. What if she is in fact more close to 100 years old. After all Echidna can foresee the future at least partially. So who could have been the mother if Minerva is out of the picture? What about Pandora? Then again Pegelguese was 402 upon death according to wiki.

4:11 So Carmilla is into emo-boys, huh

Great content per usual.

Is it plausible that Emilia is indeed around 115 years old but born before that around the time those witches lived and have been sent through time magic 300 years in the future.

I’m major confused so if satella is emilia’s mother then where does Flugel stand????( and if Minerva is her mother then I’m more confusedddd)

Emilia is a "Teenage" Half-Elf...as in the 60-80 year old Range with her Mom a Human so Emilia's Mom can't be Stella. Her Dad could have a thing for Human though and Stella could be a older Half Sister

Personally I think that Satella and Emilia are sisters, the time difference can be explained by the already established 'snow' ability that Emilia has, maybe she was frozen as a baby for example.

That's a interesting theory we might know at the end of re zero last arc probably but the big question is why are emilia and satella look alike there most be a answer for it

Thanks for the theory video! Keep it up!

Some other possibilities I can think of: 1. Satella = Emilia’s mother. Both of Emilia’s father and mother are half-elf (Emilia’s father is not necessary full-elf like Fortuna). 2. Satella = Emilia’s sister. They are daughters of a witch. Echidna knew Emilia’s mother via Satella. 3. Emilia = Satella’s clone. Echidna considers Satella as Emilia’s “mother”. Fortuna mentioned who adopted/raised Emilia as her “parent”. 4. Pandora = Emilia’s mother. She turned evil after getting the witch factor, and possibly rejected her past. Hence, Fortuna consider Pandora as “the one who killed Emilia’s mother”.

i figured it out, emilias mom is chloe aubert in a different timeline and subaru is rimuru

I'm calling it here, it's either Pandora, or Echidna.

I feel Emilia and satella are twins and their mother is echinda, minerva, or carmilla

I we are in realm of theories my theory is that Sattela is Emilia twin sister, look we know that at least in case of Echidna witch powers were inheritor so it is rational to assume that older sister get's the power, so it their mother was previous witch then they left Emilia to protect her but took Satella to prepare her to inherit powers. The could keep this in sceret form Emillia to make living apart form them easier for her

Re: Typhon, while I don't think Typhon is the mother, I don't think you can assume that the age the witches appear in the tea party is the actual age of the witch. Remember, Emilia couldn't recognize the body in the coffin, with the body looking much older than the Echidna Emilia met in the trials.

I had always theorized that Puck was made by Flugel and not Echidna. Flugel creates Geuse who guards Emilia and fails, then creates Puck (which I believe is just a fragment of himself much like the Omega/Fox Echidna discrepancy, which explains Puck and Fox Echinda's memory loss) to guard Emilia. Flugel is definitely in the Emilia/Satella camp more than Echidna is. As for the timeline I think its a misunderstanding, Flugel (who is now Puck) was searching for *Satella* for three centuries (100 years frozen, plus two hundred years of being apart), Emilia is just the *reincarnation* of Satella. Flugel>Geuse>Puck>Subaru all are connected and seem to have the same mission as each other, Flugel shares being from the same world as Subaru and Puck share the same voice ticks as Subaru whenever Subaru dies in a loop (which to me just confirms Flugel Puck and Subaru are the same person). Btw these are all conclusions I came up with by myself, I'm really rusty and haven't really kept up with Re:Zero stuff in a while so I haven't read the latest LN or side story content so feel free to correct me or discuss.

About emilia’s age,It could be that Puck was created before emilia was born since during arc 4 we learn that echidna can “read” the future so she might have predicted that

What if Emilia and Echidna have the same mom.

But didn't fortuna said that she and emilia were not from the elior forest? She said to archie that she caused a lot of trouble to his people(wich means that emilia and fortuna are both from another place unkonow to us) + why geuse wants to protect emilia that much if he didn't had any connection to minerva rather he was close to dona more I guess that dona is emilia mother but idk wich version

Lowkey I thought: Echidna x mystery man (amethyst eyes, silver hair, elve) had 2 children: - Emilia - Satella This would explain the visual similarities between the two and would also explain why Echidna strangely has the same sentiment for them (hatred). It might also explain why the two posses strong magical abilities/large amounts of mana as does Echidna. Echidna stated that Emilia is as stubborn as her mother and that her mother is part of the reason for her hatred towards Emilia, which might be due to self loathing for whatever reason (and would be a great curveball that i could imagine Tappei pull off). Echidna could also be described as having a "gentle face" which Emilia could have inherited from her. It is stated that 2 persons are able to open the seal in elior forest. One is Emilia and the other one yet to be revealed. The 2nd person could therefore be Satella since that would also explain why genetically she would also meet the exact same requirements as Emilia. Even Fortuna (100+ years ago) is often confused as where Emilia has her ancient words/expressions from which might imply that either Emilia is a lot older or that she would have learnt them from a person (e.g. her mother) that is a lot older. Mutually shared Tonedeathness with Echidna. (on further notes i could also imagine Emilias huge amount of mana being the result of one of Echidnas experiments) (That Echidna has not even one child could be a curveball especially since Echidna is stated to be considered the mother of some spirit that she created. This makes Tappeis answer seem a bit odd. Furthermore this would not rule out that Emilia (and Satella) is a child of hers in a similar manner that spirits are or through an experiment)

If this is true, then the seal in elior forest hosts minerva's remains, and she has a history with elfs so it would make sense for it to be with the elfs. If she is the witch's daughter, then that is why she can open the seal.

Just throwing my theory: 1. Satella mostly likely Emilia herself. Seeing how much her love to Subaru, it seems unlikely Satella will be other girls. The author needs to have a VERY good reason why she is not Emilia 2. Echidna hatred to Emilia due to her mother. This one is weird. Echidna also hate Satella. Not sure why. Satella is not the one who killed all of them. Even Echidna was not killed by Satella 3. Most likely Satella is the mother of Emilia and Subaru himself is the father. Yeah, this is isekai. We can throw all common sense in reality. Time traveling? maybe. going for another isekai as an elf? giving off info as the brother is an elf seems like an attempt to eliminate Subaru as the father 4. The hidden information is how Emilia is made. She might be the reincarnation of Satella herself. Not actual daughter but she is called daughter in the community. So Satella = Emilia. I think I can accept why Echidna treats Emilia weirdly. Nervermind, just a stranger throwing off theory

I think emilia is either a reincarnation of satella like they both reincarnated with flugel to emilia and subaru or satella is emilias grandmother and mother in law of minvera

Subaru's biggest mistake in the trial was not asking if all the witches working together would help him reach a happy future with emilia

You forgot to mention how Minerva acted when meeting Emilia in the trial in the anime how she couldn't look her in the eye or let her see her face

Emilia's mother is Echidna

one small issue i think its a mistake to assume emilas parents are from only one race, fortunas brother could be a half brother who is half human half elf, then her morther could also be half human half elf, making emilia still half human half elf

Q. Who is Emilia's Father? A. Betelguese (Shown in flashback) Q. WHo is Emilia's biological mother? (Not Fortuna) A. Minerva because sirius assumed that its Mother is Fortuna

Wait, assuming this is true and Minerva is Emilia's mother then that would feed really well into the other common theory of Satella being another version of Emilia! Remember, Satella is incompatible with the Envy factor which is how the "Witch of Envy" split personality came into existence, perhaps that incompatibility comes from being the biological daughter of Minerva who embodies the sin of Wrath, it would fit well!

Satella might be future Emilia who went into past. From what satella said, subaru sacrificed himself to save her or others and so satella gave him the powers so that he will live no matter what. Echidna said satella's only objective is for subaru to survive. And why would she want to save him if they had never met before.

Idk why but i dead ass thought echidna was an elf this whole time

Waitwaitwaitwait. We know Emelia looks EXACTLY like Satella. In arc 6 her hand fit perfectly in an impression that was implied to be made by Satella, so it's not just her face. What if Satella's spirit was sealed away, and Emelia's body was left over? It would make sense for Satella to possess Emelia, since it's her body. This would make Satella Emelia's metaphorical mother. It would also explain why the fire horse thought Enelia was destined to bring destruction; she's a mind wiped version of Satella. It would also explain why a certain somebody thought Emelia was Satella, despite having known Satella personally
