The sixth season of Glee will have its cast go back to the past and reflect what made them decide to join the club in the first place before the season wraps up.
The synopsis of the February 27 episode entitled "2009," as shared by Carter Matt read: "Glee goes back in time to see why the original members of New Directions signed up for glee club in the first place."
It will feature regulars such as Lea Michele (who plays Rachel), Chris Colfer (Kurt), Darren Criss (Blaine) and Chord Overstreet (Sam), as well as guest stars from the original cast, including Mark Salling (Puck), Kevin McHale (Artie), Amber Riley (Mercedes), Jenna Ushkowitz (Tina) and Jayma Mays (Emma).
It will be a very emotional show, since one of the original cast members, actor Cory Monteith who played Finn Hudson passed away back in 2013 due to a drug overdose.
His character Finn was a well-loved character in the show. At the beginning of Glee, he was the star of the football team and he was dating head cheerleader Quinn Fabray (Dianna Agron). He was the object of Rachel's affections and they only became a couple a few seasons after.
TVLine earlier got in touch with show creator Ryan Murphy and asked him how Glee will end without one of its main stars. Murphy admitted that it would be difficult to work around because he always envisioned Rachel and Finn together during the last episode.
"The final year of the show, which will be next year, was designed around Rachel and Cory/Finn's story," he said. "I always knew that, I always knew how it would end. I knew what the last shot was - he was in it. I knew what the last line was - she said it to him. So when a tragedy like that happens you sort of have to pause and figure out what you want to do, so we're figuring that out now."
But he did say he has a good idea how to provide a fitting end to the show, which will be "very satisfactory" and in honor of Monteith.
Fox President Kevin Reilly also said earlier that they might consider extending Glee only if they were able to find breakout stars to add to the show.
"Never say never, but... there's two very clear arcs to get to that end and conclude the series," he said. "If we discover a new crop of kids and there's some breakout, who knows. But right now, we're thinking about two seasons."
