Peter and Neal in “Unfinished Business”

Peter

You ever wonder what would've happened if I hadn't made you my C.I.?

Neal

I'd still be in jail and your arrest rate would be in the low 70s.

Peter

High 80s.

Neal

Why did you take my deal?

Peter

I told you, your expertise.

Neal

That's all?

Peter

I realized... all those crimes you were committing, they were never about money, or greed.

Neal

What do you think they were about?

Peter

The challenge. That's what we have in common. I love the challenge.

Neal

I know you do.

Peter

And after all those years of chasing you, your cryptic clues, your late-night phone calls from international numbers...

Neal

Yeah, and the cookies, and birthday cards...

Peter

Yeah. I realized I liked you. That's why I took your deal.
