Well my personal opinion is that with the exception of Libra, the remaining spirits are the stronger ones, and will take at least a whole episode to take out. Just because it was 2 episodes per spirit before, doesn't mean that trend will continue. And given how much happened in this arc you would need at least half an episode to wrap up the arc (changing the spirits to normal, cs world returning to normal, revelation of where the cs king has been, possibly a more clear explanation of exactly when and how this happened and probably a little re-union where every kiss and make-up, given how fairy tail and filler is).

I will correct myself and say that 3 episodes will the minimum. But i wouldn't be surprised if we ended up having 5 episodes left.
