As for the outcry over Karofsky returning, Falchuk admits, "I have a lot of angry tweets. But look, it's a new season and we're exploring some stuff. We love Kurt. We love Blaine. We love them together. We love them apart. We love them all kids of ways. And I think that their relationship is a really great place to explore some more complicated stories. Really, it's going to be OK."

Falchuk also reveals that the writers have come up with what the very last scene for Glee will be. (The original idea involved Cory Monteith's Finn and Lea Michele's Rachel.)

"Yeah, I think we've got it."
