Clockwork Prince question

OK, I finished reading Clockwork Prince a while ago and I can usually guess what is going to happen. But after seeing that Jem, proposed and she said yes what will happen. I mean, I really want her to end up with Will but I'm not sure how that will happen because Tessa already turned Will down. I like Jem and all but I don't want him to be with Tessa more than I want Tessa and Will together. So she doesn't want to break his heart. Me and my friend had this conversation and she said that Jem should die. But Jem is a really nice guy. But Will could be as nice too because he pushed everyone away so he doesn't hurt them.


So what do you think?What will happen?
