- I was kind of hoping to talk to your sister, Gillian if she's around. She might have some information on a case I'm working on.

- Oh, all right, I'll get her.

- All right.

- How did you know that I was her sister?

- Oh. Lucky guess, I guess.

- Mm.

- Uh, why don't you come inside?

- Gilly. Gillian! Gilly. Gilly, there's a cop downstairs and he's looking for Jimmy and he wants to talk to you and I think I'm having a heart attack.

- Okay. Just calm down. Calm down. Okay.

- What is the question? The question is, How much can he know?

- Well, gosh, well, he seems to know an awful lot because he's come all the way from Arizona.

- And I know this sounds really strange, but I don't think I can lie to him.

- Oh, my God. Of course you can lie to him. Breathe, breathe.

- Here is the story, right? Here's the story. I left him...

- Left him....

- Because he hit me.

- Hit you.

- And we haven't seen him since. And it's as simple as that.
