Since his introduction to the show in 2010, Darren Criss’ character Blaine Anderson has been a huge fan-favorite on Glee, and seems to be the perfect match for Chris Colfer’s eccentric Kurt Hummel. All has been well since the two characters started dating, but in Tuesday night’s episode “The First Time”, Warbler Sebastian (Grant Gustin) will try to break up everyone’s favorite couple!

The new Warbler has his eye on Blaine, and based on the PROMO released this week, he has no qualms about hitting on a taken man. “It doesn’t bother me if it doesn’t bother you,” comments Sebastian. But Kurt quickly arrives on the scene to keep things from getting out of hand – and accepts his new adversary’s invitation to a gay bar.

And that’s not the only drama we can expect tomorrow night! Despite Sebastian’s flirting, Kurt and Blaine will be losing their virginities to each other!

“It was definitely a big issue, something that I don’t believe has really been seen on TV too much before: two gay kids losing their virginities,” Chris told EOnline.

Do you think Kurt and Blaine will be able to survive Sebastian’s advances this season? Let us know in the comments below!
