According to TVGuide, co-creator and executive producer Ian Brennan has revealed that GLEE fans should expect a Grease-themed episode this season.

"Our Grease episode, which we just finished writing, I think, is certainly our strongest episode in a while. It just ended up really funny and sweet and weird," Brennan told TVGuide.
