‘Glee’ Season 6 Spoilers: Kurt And Blaine’s Relationship In Jeopardy With Dave Karofsky’s Return? Warblers Set To Take On New Directions

"Glee" season 6 spoilers reveal the return Dave Karofsky who spent much of the previous seasons being a hindrance to Kurt and Blaine's relationship. Meanwhile, the Warblers are also posed to come back perhaps to challenge the New Directions.

TVLine has dished out "Glee" season 6 spoilers when it reported the return of Max Adler who will reprise his role as Dave Karofsky. Fans of the show know Dave Karofsky as the closet gay who used to bully Kurt and Blaine.

Later into the series, it was revealed that Dave Karofsky actually struggled with his own sexuality and had a crush on Kurt. In season 3, he tried to commit suicide after his secret was exposed in the school. His plan was averted after his former victim made him realize that he could have a good life as a sports agent and a family of his own.

Kurt and Blain survived the Dave Karofsky saga and they have forged a strong long-distance relationship and finally entered season 6 as an engaged couple.

Max Adler is poised to appear in "at least four of the show's final 13 episodes, The Hollywood Reporter said.

Meanwhile, WetPaint reported that the Warbler could be back in season 6, based on the photo tweeted by Nolan Funk (Hunter Clarington) as he posed with Darren Criss, who plays Blaine. He also captioned the photo: "#WarblerSelfie @DarrenCriss @GLEEonFOX."

Hunter at one point became the leader of the Warblers but was kicked out due to a drug scandal. Sebastian (Grant Gustin) then took over again the leadership of the group.

Jane Lynch (Sue Silvester) earlier dished out "Glee" season 6 spoilers to Entertainment Weekly  as she said that the old rivals of the New Directions might be coming back.

"I think we're going to have some surprises about who's going to be the choir director of The Warblers and who will be the choir director of Vocal Adrenaline. I think it'll be a big surprise," she said.
