^The creators said they have a five season plan. Could be a bit much and there's no guarantee they'll get it, but they've got plans:

Well, this is kind of ruined now that (Episode 5 spoilers) Crystal is dead despite munching on Jackie meat and Ben is still alive and actually looking a bit better than two episodes ago.
Episode 5 was the best of the season, I thought. Callie teaming up with Shauna and Jeff is much more fun than her rebelling against them. Flashback Misty has been a bit softer lately with her new friendship, but we got a great reminder of how unhinged she is (and a great performance from Sammi Hanratty) when she caused Crystal's death.
Walter will definitely be back. He seemed a bit too into the idea of Misty being a murderer.
So now it looks like the Antler Queen wasn't one of the yellowjackets but rather Javi's mysterious friend...
