I understood. I just do not think it is a factor of any importance.
Yeah, I don't think the usual "feeding on emotions" was happening here. Lara loves her brother, and that is what she was feeding the Hunger to try and keep Thomas going. To survive apparently the Hunger will eat anything at this point, including it's host, which makes no sense. Because once it has "eaten" Thomas and he dies, it dies as well. So two possibilities, the Hunger Demon really is just a mindless parasite not knowing what is in it's best interest in it's effort to survive.. Or it has a way to move onto a new host once it's present host is dead, so it survives.
