Or you can go a more original route, maybe do like a two or five years time skip where we can see a negative effect of getting rid of malavore. You can tweak the reason it was made, to something like malavore was a way to get rid of all the negatives/bad supernatural. Since he's gone it through the balance of good and evil off. (I think original, haven't found a book that went this route) I don't if that makes any sense. The fact that they showed the positives of malavore but not the negative of destroying him, was something I always thought of. You don't really have to use any of this. These are just ideas I would have like to see if the show didn't got cancelled.
