Grace being an even BIGGER waste of space than Zoe.

Tragic. I mean, really. Ryan had the chance to make Grace's killer reveal AMAZING. All the signs pointed to her. Even if Hester was still a killer, it would have made sense, since they're all siblings. That would have been why Grace survived the attack, using Hester to make her look innocent and kill Pete. I feel like he really lost his way, and just needed something to wrap the show up. I hope it's not cancelled, but I wouldn't be surprised.
If it's not, roll on Scream Queens: Asylum.
