I love the idea of them going from boxcar to sex to a con using their 'respectable face'. There's something kind of gritty and satisfying about that. Wish I could articulate why better for you. :(

Also like that Arthur sees it as a more solid boundary from his old life to the new.

And of course the sex. I'd have loved to have seen that from Eames pov, too. Just the fact that he 'fessed up to Arthur and gave him to opportunity to pass, and how he got from angry erection to wanting to be honest would be fascinating. ♥
