Grown-up timetraveling!Hope is very similar to Snow, I think. I think the differences lie in exuberance and the way each of them have depth.

Hope's depth, from what I can understand, is his quieter side, the side with the feelings and the way he takes in the world. His empathy, in other words.

Snow's depth is a little different, in that he keeps going and believing and believing, but when his doubts are picked on and prodded at, he becomes a mess of a man, struggling to find the belief that fueled him.

Both of which are really compelling.

Anyway, I'm apparently in a thinky mood today, XD

Sorry if I type your eyeballs off.
