We made it! Glee Season 3, Episode 8, "Hold on to Sixteen," will show New Directions go head-to-head against The Troubletones at Sectionals.

Chord Overstreet  (Sam) is set to make his much-anticipated comeback in this episode, but will Trouty Mouth rejoin New Directions to give them an extra push? It's not like he can join ex-GF Mercedes (Amber Riley)’s new group (sorry, Sam, girls only). Honestly, we’re happy if he just sticks around!

Plus, Quinn (Dianna Agron) has an "important decision" coming up, which we bet has something to do with baby Beth, while Tina (Jenna Ushkowitz) stands by Mike (Harry Shum Jr.) as he makes the call between professional dancer and doctor school.

But, if for no other reason, stay tuned to the return of The Glee Project's Lindsay Pearce, reprising her role of Harmony, and the return of Dalton's newest bad boy Sebastian (Grant Gustin)!

"Hold on to 16" is set to air December 6, 2011.
