'Dramatics' oh man, the moment he says that about her, that's going to turn into a fun, fun scene.

Angry because Elizabeth did something human, that he really wanted with her, when he had accepted that it couldn't have happened?
If he really wanted to raise a child with her, I can understand how seeing her say she raised a son would feel like a slap to the face.

That would make sense for them to eventually encounter each other again in that fashion.  The way you say hunting though, is that what you're thinking of the Reese clan doing?  Going more old-school with hunting humans? That would definitely create conflict between the clans and definitely bring about a confrontation.
