The rumors of Naya Rivera (Santana) and Lea Michele (Rachel) feuding on the Glee set are common knowledge these days (and may or may not have gotten Santana’s portrayer fired from the show) but now it looks like there’s a new battle brewing on the set of the FOX dramedy. Say it ain’t so!

However, we probably should have mentioned that you can rest assured that this latest feud is all in good fun. We think. As you may recall, several weeks ago Lea and co-star Chris Colfer (Kurt) participated in the first ever Brain Busters, a trivia game that pitted the two pals against each other while Darren Criss (Blaine) acted as a host of sorts.

The first iteration of Brain Busters was a Broadway edition in honor of the Stephen Sondheim-centric ep, “Bash,” and apparently “part deux” is on its way. No word on whether or not there will be a theme this time around, but both Lea and Chris are clearly ready to fight to the death.

In a preview clip of this next duel posted to Instagram earlier this week, Lea, who lost the last round by one point, is understandably fired up as she sits next to Chord Overstreet (Sam). She practices hitting the correct answer button, makes a series of funny faces, and then ominously declares, “Colfer, I’m coming for you.”

With a threat like that, Chris had to respond. FOX posted a video of him and Darren, during which Chris weighs in on Lea’s fighting words. “Would you like to say anything to your challenger Lea Michele?”, Darren asks. In response, Chris dings that same correct answer button and laughs aloud. “I love that sound,” he concludes.

Part one was a close call, so by our estimation Part Deux is anyone’s game. We’re expecting to catch the second round of Brain Busters sometime today. Are you Team Lea or Team Chris? Sound off below!

Glee Season 5 airs Tuesday nights on FOX at 8 p.m. ET.
