In a recent Ask Ausiello column, Michael Ausiello spoiled that a character he "never thought he'd see on the show again" is coming back to Glee soon. We know that Grant Gustin's Warbler character, Sebastian Smythe will be recurring again this season, but that's all out in the open.
Could Ausiello be talking about Max Adler's Dave Karofksy? It doesn't seem highly likely, considering it's been said over and over again that there are no immediate plans to have Karofsky return to the show, even for a guest appearance. Then again, things can change. Then again, he could be talking about Damian McGinty's short-lived Glee character, Rory Flanagan.
What unlikely character do you think we'll be seeing again soon on Glee in season 4?
