The last time we saw Quinn (Dianna Agron) was in last season’s 14th episode, “I Do.” And after she didn’t return for the Cory Monteith tribute episode (Season 5, Episode 3, “The Quarterback”), we were pretty sure she was gone for good.

But maybe we shouldn’t give up hope yet. We’ve got a hunch that Dianna might be returning to Glee for this season’s Christmas episode, Season 5, Episode 8: "Previously Unaired Christmas." This December 8 episode will take place in Glee's past. Could Quinn heading back to Lima to be a part of it?

Of all the grads who are no longer regulars on the show, we know for sure that Puck (Mark Salling) will be making an appearance. Last week, when Mark tweeted a picture with Glee vocal contractor Tim Davis, it was kind of a dead giveaway that we’ll be seeing Puck for Christmas.

Because Mark will be back, we think it’s totally plausible that Dianna will be, too. And by our logic, if one of the grads is returning, it’s not too far out there to assume that a few others, could, too.

Who else is on our list of possible returns? Mercedes (Amber Riley). Lately, Dianna’s been tweeting with Jenna Ushkowitz (Tina) and Amber, which leads us to assume that they’re spending time together… and they’ve been tweeting together. Maybe we’re overthinking this, but we think these are all solid clues that could point to Quinn’s return!

Do you think Quinn will be back for the Christmas episode? Let us know what you think below!
