Can we seriously endure another shocking Glee Season 4 break-up? There’s been too many already, and frankly, we’re ready for them to stop. Unfortunately, it looks like we might not have any choice.

Entertainment Weekly is revealing that someone will be cheated on in an upcoming episode, although they won’t divulge who the characters are. Long story short: There will be tears.

“I just found out a few days ago that [SPOILER] cheats on me,” a cast member says. “I did not expect that from that character.” Gah! Don’t go breaking our hearts again, Glee.

The mystery cast member goes on to say that he/she would like to throw a fit about the infidelity. “I would love it if [SPOILER] gets really mad about it and vindictive,” continues the cast member. “I can play a mean and vindictive.”

So who might this be referring to? We’re stumped, since there aren’t even many stable couples left on this show. Certainly, it would be a pretty big surprise if either Brittany (Heather Morris) or Sam (Chord Overstreet) were to cheat on each other, as it would be ifRachel (Lea Michele) cheats on Brody (Dean Geyer) with — gasp! — Finn (Cory Monteith). And don’t get us started on how we would feel if Wemma cheated!

But perhaps our jaws would drop the most if Marley (Melissa Benoist) cheated on Jake (Jacob Artist), which might mean that Jacob is the one who wants his character to get vindictive. Then again, maybe it’s Jake who cheats, meaning Melissa is surprised that Jake would actually do that to Marley. We just don’t know, people!

So who do you think cheats? Tell us in the comments! But don’t say Lord Tubbington, since that wouldn’t be a surprise choice on the show’s part. Lord Tubbington clearly gets all kinds of action.
