Hope is being a little *female dog* about the whole thing, it is obvious that it wasn't Snow's fault.

Lightning is mad at him because she never approved of him in the first place. And having what happened to Serah didn't make her mood any better.

I didn't dislike Snow, but he also didn't seem like the sharpest knife in the drawer. Though overall he is a decent guy, if I had to spend any time with him in real life I would probably want to punch him in the face too.
