According to Chord, this episode involves ‘the funniest song of all time’.

Glee is looking for a ‘Nerdy African-American Kid” for an upcoming scene.

This is the first in a 6 episode arc that will lead to the confrontation at Nationals. Sue (after losing Regionals) is determined to make sure that New Directions loses at Nationals. To do this, she begins to enlist what producers have currently called the Legion of Doom in order to giveVocal Adrenaline the edge at Nationals.So far, confirmed members include Dustin Goolsby (Cheyenne Jackson),Terri Delmonico (Jessalyn Gilsig) and Sandy Ryerson (Stephen Tobolowsky). April Rhodes (Kristin Chenoweth) and Sunshine Corazon (Charice) will return during this 6 episode arc and Holly Holiday (Gwyneth Paltrow) will be making her third appearance during this arc.

Kurt will return to New Directions and William McKinley High School and Blaine will supposedly join him. Blaine and Kurt may join New Directions before the Nationals arc begins, meaning they’ll either join at the end of the previous episode or sometime during this episode.

Since Kurt and Blaine will be at McKinley now, It’s possible that this is the Karofsky centric episode that will also feature Born This Way because they are more likely to interact now that all three of them are at the same school.

Chord Overstreet filmed a scene and then went to record a song.

Jessalyn Gilsig (Terri) was on set filming scenes.

Stephen Tobolowsky (Sandy) confirmed that he’s back on Glee.

Cheyenne Jackson (Dustin) tweeted about Jane Lynch, most likely he’s started filming.

Holly Holiday is back, this is her third appearance.

Amber Riley (Mercedes) tweeted that she has recorded a song. Source and she said she is filming a “very big scene”

Despite rumours, Jesse is apparently not returning this episode as he’s not filming in this episode.

Various SYTYCD members that were part of Aural Intensity have been tweeting about filming a Glee scene with a song. With work on Original Song completed, its assumed the students transferred to Carmel High and Vocal Adrenaline as part of Sue’s plot.

Kurt’s personality will turn 180 degrees. He will become stronger and eventually will confront Dave. Kurt will now have a crush on Sam.

Rachel will have another diva attack and leave the choir for a few days and in matters of love, she will have an affair with another member of the Glee Club which is neither Finn nor Puck.

Sue will return to her old routine of tormenting Will, but take a few days vacation to relax. Rumor has it she could find love with someone new.

Artie will be on the line in the glee club and will have to enter a competition with Puck to see who stays and who goes. Will he achieve it?

Emma is found at a crossroads and could deceive her husband for Will.

Will has a torrid affair with the sexual education teacher.

SophieYan: What happened to Cheyenne Jackson's character on Glee?
From the Department of Completely Unconfirmed but Plausible and Fun Rumors That We Can't Not Share: A source tells us that Gwyneth Paltrow's Holly Holliday ditches Matthew Morrison's Will Schuester in favor of Vocal Adrenaline coach Dustin Goolsby (Cheyenne Jackson). Man, this has been a tough year for Mr. Schue in the romance department!

Question: Before I have my knee surgery, I need some Glee spoilers. I’ll take anything. —Shannon
Ausiello: Look for some romantic shakeups in the adult world, specifically involving Will. Hint: There’s a reason Gwyneth Paltrow’s Holly Holiday is back for more than one episode. And despite speculation, it doesn’t involve Cheyenne Jackson’s returning Vocal Adrenaline coach, Dustin Goolsby (although he does make a play for her.)

leslie97193: Quinn and Puck are perfect for each other. Why have the writers ignored them this season?
If only we were flies on the wall of the Glee writer's room, then we would totally answer that question. Alas, we are not. And it probably won't make you feel better to hear that this whole Finn (Corey Monteith) and Quinn (Dianna Agron) reunion tour mess isn't over yet, huh? Don't shoot the Glee messenger!

John Stamos (Carl) will be back on Glee tonight for the first time in 2011, but does his return mean we should expect John to stick around for Season 3? Don't bet on it, says the Glee star.

"I think the story is going to end this season," he told Access Hollywood. "I'm going to back and do a few more [episodes.] Initially they brought him on to be in a triangle with Will and Emma."
