Criminal Minds, Season 3

Prentiss:
So Hotch is even more intense now that Gideon's gone.

Reid:
Yeah, I've noticed.

Prentiss:
Do you think that's gonna change?

Reid:
Certainly think we'll find out.

Prentiss:
What about you? You ok?

Reid:
Oh, I'm-I'm great.

Prentiss:
Do you wanna talk about it?

Reid:
What's there to talk about, really?

Prentiss:
Gideon.

Reid:
Oh, no. He uh-He left a letter explaining everything. Just like my dad did when he abandoned me and my mom.

Prentiss:
He addressed it to you.

Reid:
Yeah, yeah. You know, Gideon stood toe to toe with some of the, the sickest people on this planet. I think that took a lot of courage, right?

Prentiss:
Yeah.

Reid:
So, why'd he do this? It's addressed to me, but I'm-I'm not-I'm not the only one that he abandoned.

Prentiss:
But why is it addressed to you? [Reid looks at her] I think you need to read that letter again.

Reid:
I have an eidetic memory, Emily.

Prentiss:
Ah, yeah, I know, and an IQ of 187, but what do you remember about your father?

Reid:
What do you mean?

Prentiss:
Well, he gave you ten years before he left, and yet, you've erased all those memories. And-it's too painful. I get it. But then, Gideon leaves. I think you need to read that letter again, and ask yourself why, of all the people he walked away from, did he only explain himself to one person… you.
