I got caught up two days ago, and I agree with Bitt. There's just no way they can end it right now. From the previews, we know that Sophie is going to be in a pretty tight situation, and we may even get to figure out what that whole "Omega" thing is all about. We also got a huge piece of foreshadowing before the bookworm got gutted by Scudder. There are more historical documents out there that speak about this whole business. Likewise, when Ben picked up the boon from the Management, we never really learned how much he, himself, learned. All of that could come out next season.

So, for what it's worth, my guess is that Sophie has some kind of especially large role to play that's going to (temporarily) dwarf the conflict between Justin and Ben. I also imagine more than one person is going to end up dead before it's over.
