Question: How long will Matthew Morrison be off Glee? —Jenna
Ausiello: Just a handful of episodes, I’m told. Long enough for Finn to get comfortable filling in for Will as choir director — a little too comfortable, if you know what I mean. Teases exec producer Brad Falchuk: “Will’s going to come back and there may be a little competition between them.” Bonus Glee Scoop/Riddle: Sue will soon be privy to a secret involving Mrs. Rose (a.k.a. Marley’s mom).
