I love that he's wearing his gryffindor tie!

I love how he is as excited to see the Mugglenet people as any huge HP fan would be. So authentic. What a great guy!

"I've been standing next to Tom Felton for twenty minutes, what's up with that?" Hahaha I love him :)

When he said "You're not alone" in Glee, I fangirled like crazy.

I may have laughed when he said "you're not alone" in that particular episode, and expected him to burst out into song.

0:09 "Yeah, LET'S!" >> omg he is sooo excited it makes ME excited! Be more adorable Darren, I DARE you.

:D This makes me SO INCREDIBLY HAPPY. I'm one of those possessive fans...and it gives me so much joy to know that Darren is still so down to earth and ahhhhh he's such a great guy. So humble. I'm really, really, really proud of him. This video is one of my favorites ever. I LOVE YOU DARREN & ANDREW!

He's adorable!! I like how excited he got when he saw you :D

Darren's totally fangirling over you Andrew!! This dude's legit into the Harry Potter fandom, and that rules!

when I heard the "you're not alone" in glee I screamed " 'CAUSE BABY YOU'RE NOT ALONE!!!" thankfully I was alone that moment ^_^

I love how excited he is to be interviewed by mugglenet.

I love his attitude in this video. I love how excited he is and happy... he's just great. This video put a smile on my face :D

I liked the way he said 'no' when they asked him if DH was his favorite book.

I think it's absolutely adorable how excited he is!!

I FINALLY KNOW WHY HE IS SO SURPRISED TO SEE THEM OMG I'M CRYING

LOL I love how he's freaking out over Mugglenet being there interviewing him,and Matthew Brodrick and Sara Jessica Parker are like,feet away from him.x3

Lol. I love how excited he gets over this, and when you watch his other interviews he seams very chill compared.

Love him! He's just gushing about how much he loves HP and Glee!

I love how he is so excited to see the mugglenet crew, much more excited then when he talked to those Enews guys who only wanted to hear about glee. nerds are the best :)

That sweater matches his eyes incredibly

Andrew Sims interviewing Darren Criss... my Harry Potter fangirl heart is happy. XD

I love how excited he is to meet Mugglenet and Leaky Cauldron!

What a friggin' cutie pie. :D I absolutely love him on Glee! and this just makes me love him more. Nerds rule.

This is so cute! "I'm actually supposed to be outside" =)

Darren Criss's dorkiness and enthusiasm is just so mesmerizing I didn't even notice Matthew Broderick and Sarah Jessica Parker in the background until the 2nd viewing.

he's so cute when he says, that he he just wants to do what they say ... :) love ya :D

omg.... the tie! that's the cutest thing ever!

i love how he has a gryffindor tie on!

He knows what a fandom is. HE IS ONE OF US!!

YES DARREN. WE DID KNOW. WE FREAKED OUT WHEN YOU SAID "YOU'RE NOT ALONE."

He loves the early ones... Darren, me too, I know what it is :D And I just love how humble he is when he says that he can't believe he's on the other side of the premiere, INSIDE, rather than with all the fans, as himself. He's amazing.

I am in love with this guy! Ahaha love the tie Darren!! ;)

I LOVE LOVE LOVE how exited he is!

I love this! It feels like "we" have someone on the inside now!

"Oh we knew Darren when.." ya, I'm totally like that xD I'm always telling my friends that I knew Darren before he was on Glee and stuff

i definitely noticed the "not alone" line on glee. that made me freeeak out haha

I love that his mom is in the background at 0:13 to 0:17. so sweet :)

I love how he's fangirling and he's wearing his Gryffindor tie! :D

"Can you try to get some Harry Potter references in Glee now?" Chord winked at Darren and said "totally awesome" I flailed XD

He's so freaking amazing :D

This is all sorts of EPIC WIN. I love MuggletCast (and Andrew). I love Darren. I love that Darren's sweater matches his eyes:) I love how Darren is SUPER excited to talk to the guys from Leaky and Mugglenet:) HP love and Darren is such a good combination.

i love this so much. he's just so excited to be there and so grounded, meanwhile all these like grumpy celebrities are like walking around behind him. i am so happy for this guy, i really hope that he continues to prosper, and that he gets the chance to meet daniel radciffe!

he's so nerdy! I LOVE HIM. :)

He is always so exited. bless him :D

When he's excited it makes me excited!!!!

When he leans forward toward the camera to hug that guy, I feel like he's hugging me :)

Oh, my god, he is just too cute freaking out about this interview! Best one of the night, hands down!

I LOVE HIM SO MUCH

HES SO EXCITED AND DORKY AND I LOVE HIM.

I'm happy that guy was so close to the camera, at the end if feels like Darren is hugging me.

He's cute! and it's hilarious how excited he is.

Wow he's cute. And he's a Harry Potter fan. And he's a good actor. How amazing can a person get?

I love Darren so much! This interview was totally awesome!

Good man- I love him so much more just from this.

He is so adorable!!

SO cool! Darren Criss is so rad. he's like THE quintessential HP fan. AND THANK GOD he mentioned that StarKid fans are WAY too possessive of him. You're the man, Darren!

OMG i got that reference!!! my family looked at me like i was crazy..... Darren criss is my hero :)

I love how Darren is so excited to meet the creators of Mugglenet. XD

He's so excited to see Mugglenet and Leaky like he can't believe it!!! OMG I love Darren Criss so much. I used to think that he was just kind of embarrassed about AVPM and wanted to hide it but now I see that's the opposite of true, and he's actually a die-hard HP fan just like us.

Mugglenet+ Darren Criss! Best interview ever!

I love how excited he gets :P

AWW! he's so cute! i love him!

OMG HE MAKES ME SOOO HAPPY!!!!!!!!!!

Haha when he said "You're Not Alone.." I totally started singing along to the song XD

freaking love darren criss he was ours before glees YA!

This is pretty much the best thing I have ever seen. he is SO STOKED to see mugglenet and Leaky that he doesnt give a shit that Matt Brodrick and Sara Jessica Parker are right behind him. I love that no matter what, he's still one of us. Just a fanboy that made it.

i love how in the beginning he keeps interrupting them and freaking out!!!! :D hahaha!

He's so cool! I love him and Harry Potter!

@LenaCS same here. I think all of us geeked out just as much as they did when they saw each other! So great!

Aww, yay, so glad he got to go, that is so awesome, hope he liked it because I did ^^. Also, random spotting of Matthew Broderick and family, that was also awesome.

We are so proud Darren!

@totallyforsure the line was "You're not alone", he was saying it's kind of a reference to A Very Potter Musical, one of the Harry Potter shows he did before joining the Glee cast. 'Not Alone' is one of the songs he wrote for the musical.

I've seen this so many times and can't help but smile. Yay for being fanboys and being okay with it!

I love DARREN is more excited to meet THEM than they are to meet HIM. Lol! It's so cute to think he started out as just one of us, a huge Harry Potter dork who made it big but is still just like us underneath ;D

OMG I loooooove Darren Criss! :)

Andrew Sims and Darren Criss. Together. HWOOOOAAAH!

aw..... so inlove

he's so cute at the begining!

Darren so AMAZING!!!!

What a lovely guy!

I LOVE this kid!!!!

Lol 'Holy shit, man! I am allowed to say shit right?' 'Well, we'll bleep it out, whatever- so, listen, you started with...' 'I can't believe you're here right now man- this is like the coolest thing ever!' Haha.

0:28 the kid in the background is just as cute as Darren!

"On the count of three, name your favorite 2010 Vogue cover! Okay, ready? One, two, three..." "Marion Cotillard!" That was totally an AVPS reference

2:07, Thank you, Darren!

I adore him!

Darren, every StarKid fan started singing "Not Alone". I know I did.

I recognised and freaked at the Not Alone line!

"WHAT THE HELL, RIGHT?!" heheee so adorable.

Awesome Tie! Love it man!

I've never seen anyone so excited after discovering they were going to be interviewed by the Leaky Caldroun... :DD

I love him.

This is supermegafoxyawesomehot, thanks Andrew!

I love how this kid is so excited, and oh, nbd, Matthew Broderick and Sarah Jessica Parker and their kid are all in the background... It's true though, he looks so much better with the haircut- it puts the attention back on his face!
