I'm on the fence about Henry. On the one hand, he isn't given a lot of focus in general in the show, probably because Paige is older. In terms of personality, Elizabeth states Henry is "like Philip" and we see examples throughout the first season where that seems to be true in some ways. So I could imagine multiple scenarios that could fit. We sometimes saw Philip be resentful of things like the motel during the separation. But more often we saw him cope by simply switching the channel in his head--watching a hockey game or reading. So Henry might be inclined to do something similar, perhaps be saddened by his dad not having time for him that night, but not necessarily in his room moping either, simply being sad for a moment and then switching the channel to something else.
