Hey Coop, thanks for letting me win.

Mick

Beth: I have been transferred between departments about 800 times; I still don't have an emergency contact.
Cooper: Put me down.
Beth: You're my boss, and I am not certain that anyone besides yourself would look for me.
Cooper: That may have been true before, but not now.

See a little Garcia goes along way

Sam

No one has come forward for Jane. How is someone so young so alone in the world?

Beth

Son: Do you think she is alive?
Sam: [long pause] I have to assume she is.

Son: I was supposed to pick her up, the one time I didn't...
Sam: Your mother was the victim of a crime. The fault lies with the criminal not with you.

Evolution is a mighty big idea for four hours' worth of carnage.

Beth

A postmortem examination made you want to call me; I find myself firmly planted betwixed, touched and skeeved out.

Garcia

Mick: Why would he go from killing men in their 20s to men in their 60s?
Prophet: With the first four victims, he is killing the same person again, again, and again.
Mick: So who the hell is he killing now?

Cooper: Going to those dark places can be painful; but, we have to face things.
Keane: Can you ever come back?
Cooper: We can try.

This is guilt carried to an extreme. The unsub wanted to undo the horror of these murders.

Cooper

Garcia: So you want me to do multiple searches on multiple personalities?
Cooper: [smiles] something like that, yeah.
Garcia: Multi-tasking Out!
