As it turns out, Sue is a huge fan of the Kurt (Chris Colfer) and Blaine (Darren Criss) relationship, which will be revealed in the next episode, titled The Hurt Locker, Part One. In a new video released by Entertainment Tonight, Lynch previews the episode.

"As it turns out, Sue Sylvester is a huge fan of Klaine and she's going to go on a crusade to get them married," Lynch says.

Sue will apparently spend much of the episode trying to separate Blaine and his new boyfriend Karofsky (Max Adler).

"It broke her heart when [Klaine] broke up - why did they break up?!" she adds, passionately. "They were doing so well! They're such a cute couple and they were so in love, why did they have to break up?"

Additionally, fans know that Sue and Will (Matthew Morrison) aren't exactly the best of friends, and that will be shown in physical form in this episode. It is revealed that Sue has a storage space full of all the bad things Will has done to her in the past.

"Sue Sylvester kind of goes crazy and I have about a seven-minute monologue basically recounting all the wrongs [Will Schuester] has done to me," Lynch previews. "Turns out I have a storage space where I store all of my resentment. I have an actual space that I go to visit and you open it up and it's every wrong that has been done to Sue Sylvester in some kind of a physical form or an art piece."

The storage space is also where she has her secret shrine to Kurt and Blaine. It remains to be seen if Kurt and Blaine will be reunited due to Sue's manipulations and what might become of Will.

Glee airs Fridays at 9 p.m. ET/PT on Fox.
