he's sort of loving her a little bit, for what she had to go through

Yeah, he does have a little bit of a pwned look, doesn't he? I never really thought about it before, but your right. He's just so proud of her and so impressed. And I love that she tells him "don't let me fall" as a way to tell him that she knows that he won't. I could go chapter and verse about how giving her his arm (rather than putting is arm around her) is just reinforcing how strong she is, even as he's helping her. But no matter how much I love their walk, I love how he looks at her and her little sigh. (And the "Prison is a prison" bit is pretty awesome too.)
