We are only a week before the grand finale and of course storytelling wise it's smart to give us that kind of reveal. Because the interests and motives are both stronger and more complicated. Wyatt is being put on the line between two worlds, two lives, and Jessica clearly wants him to abandon one. Now I have my reasons of thinking this is not just for her own matrimonial concerns, but I won't share them here and now.
The next episodes will be intense, and a lot can happen in just two episodes. Don't think of it as such a final thing. It's probably not. Just wait and see, and focus your energy on getting our show renewed ;)
