Chuck thinks Rachel is a wonderful friend. He really likes talking to her. He also is glad he can be there for her, if not personally but by talking to her, when she's feeling down.

He thanks Rachel for being really open and warm when he's not having the greatest of days and allowing him to talk through what's going on.

He's really glad he got to meet her and hopes they get to meet again sometime. He hopes all is well with her new job and new city.

Also, since Rachel told him about what she can do, he feels a tad guilty about not telling her about his ability. He thinks she'd understand, but he's kinda worried to do that, given the fact that he feels she might be in danger knowing he's the Intersect. (Plus he'd might get in trouble too.)
