Her delivery as a serial killer is....chilling. While quite possibly a nice person in real life, I would be afraid to be in the room alone with her.

I love watching that smug smile fade when Nolan tells her her secrets are all out!!!

I loved when she stopped smiling.

The grin to frown in a matter of seconds somehow makes me laugh

Dr. Nieman managed to meet Castle once again ;)

Love how she always says “wait”

Nooooo, Annie! Why do you have to be gone? You were a big part to this show. I wish you could come back. We love you!

Annie Wersching was always one of those actors that when you saw them you were like Cool, this will be good. Doesn't matter if it was Bosch, The Last Of Us, 24, this or the other work she did. I was genuinely sad to hear when she passed earlier this year.

Absolutely love, Nathan Fillion Character John Nolan in The Rookie.

This episode was awesome comeback from the winter finale

My favorite part is when her smug smile slowly disappears 🤣

I can't decide if she actually knows something or if that was a ploy to get back in the game. I guess we'll have to wait and see

I would have NEVER resisted the urge of singing "Watching...waiting...commiserating..." and walk away singing Blink 182 laughing... Then again I am kind of an asshole...

Yep There's our new Captain.

Will you have to remember you know she did play dr. Kelly Niemanin Castle you know so who knows what her character has up her sleeve I mean only she could play this character she is so damn good at it you know she's one of the best villain and the reason why I love her villainous and the character is because she looks like a normal beautiful woman in reality serial killers aren't really looking like monsters they look like everyday people and that's why she's so good at this because she makes it so realistic I mean look at all the serial killers in the past that they look like monsters I mean they were fathers they were husband's they were you know preachers and such and such so she nailed the character only Annie could have nailed his character

I felt frim the beginning that Det Armstrong is a serial killer too. That is why he killed him and went through the notes

She'll be back

We will meet again, don’t know when don’t know where.... castle fans; if you know you know (;

I like Nolan cause of cayde 6 😂

She's Rosalind dyer because she dyes her hair rose red.

Amelia Joffey needs to come back to gh and wreak havoc! Loved her character! I actually thought she had amazing chemistry with sonny!

Looks like Dyer has a crush on Nolan do you all think will see her again in season 4?

1:06 She is a creep

Is it me or does it seem like the nolan & Rosalind's relationship remind me of Hannibal & Clarice's relationship

what episode is this?

Well she wasn’t wrong

Does anyone know why she is on her knees?

These two back together again she was bad On castle and she’s bad on the rookie

Professor Halsey?

0:25 to 0:28 SOOOO SATISFYINGS :)

Wish henk from the Chicago pd showed up

and i thought she was on death row, now its just a life sentence?

Welp, Rosalind was right

Her ending is profound. Spoiler alert.

I liked her more when she was playing his ex wife at Castle

The real question is, is she really dead

Also I think Armstrong is going to kill himself or he's going to die before the season's over just wait and see just buy that look in his eye no he's got nothing left to lose now and seeing the pictures of his you know dead wife after 5 years brought him closer to the brink of death. also with officer Chen you know she's going to go through a lot of trauma on this and even though this is fiction and reality it would almost be impossible to get through this I mean look at me. my New Year's Day at 5:45 p.m. I was hit head-on at 125 miles an hour in a car crashthey look my legs my femur and my knee cap or broken as well as my forearm shattered and I am still going through that today and it's been over fifty plus days now since the accident and I have a long way to go
