Can a POV character make assumptions about what another character is feeling? For example, could you have character Jim think that character Sally is surprised? It's Jim's POV, so he doesn't know for certain that Sally is surprised. Who knows, maybe she has a gas pain. But, is it really unrealistic for his POV chapter to have a line like: Suprise crossed Sally's face. (Or something like that.) To me, this is clearer to what Jim thinks instead of just describing Sally's features. I ask, because I've seen criticism of doing that.
