I really wish you hadn't seen that.

Tanner

Hannah: We can't be a family. It didn't work.
Tanner: Well it will this time. It will - because I've changed.
Hannah: I've noticed.

Rossi: Tanner thinks his book proves he can take care of the baby.
Hotch: And if she rejects that, he could unravel even more.
Garcia: And what happens then?
JJ: No one will be safe, not even the child.

Reid

Reid: Why are you doing a Day of the Dead theme?
Garcia: Well my stepfather's family always made a big deal of it in Mexico. And my name is Penelope Garcia, after all, so...

Garcia: You didn't even flinch. JJ's right. I told her I wanted to go scary this Halloween, and she just laughed at me. And she said that I don't have a scary side.
Reid: I'm sorry. If it makes you feel any better, you probably do.
Garcia: Really?
Reid: Yeah, the building blocks of human personality are complex, varied and multi-faceted. It's essential to one's mental health to want to express these hidden personalities and it's just a fact of nature that everybody has one.
Garcia: Everybody? You have one?
Reid: Oh absolutely.
Garcia: Okay. Okay I want to see it. I want to see Dr. Spencer's Reid's hidden personality.
Reid: Right here? Like right now you want to see it?
Garcia: I have fake blood running down my cheeks. Right here, right now.
Reid: Okay. Once you see it, you can't unsee it.

After all, what is every man, but a hoard of ghosts? Oaks, that were acorns, that were oaks - Walter de la Mare.

Reid

Mr. Sykes. We're investigating a murder, and I don't speak in parables so this should be very easy to understand. If you interfere with us in any way, I will see to it that you are charged with, prosecuted for obstruction of justice.

Hotch

Pervert: Sorry I grabbed you before.
Woman: Leave me the hell alone, or I'm going to go back inside and call security.
Pervert: It's not against the law to apologize.
Woman: It's called stalking and it is against the law. Stop following me.
Pervert: You need to calm down.
Woman: I mean it. If I see you again, I'm calling the cops.

JJ: So I looked it up. No witches were ever burned at the stake in Salem.
Rossi: Really.
JJ: Death by fire was strictly a European thing.
Rossi: Moral of the story: be selective where you practice your witchcraft.

Garcia

We had a deal. You wanted out of Wichita. Here we are. But you have to lose the 'tude or we're never going to make it. Angel, I swear you are going to love it down there. Ocean, breezes, sunny every day. No where near Wichita.
