A new promo photo from episode 5 of season 3, "The First Time" was recently uncovered, but that's not all that was uncovered - Blaine and the Pips...er, I mean the Warblers...will apparently be back in the swing of things (or at least for an episode).
Who's excited to be seeing Blaine's old pals again? With Sebastian (Grant Gustin) entering the picture, maybe they're his back-up. Mwahaha.
Speaking of Sebastian, here's a Klaine spoiler related to Sebastian from Grant Gustin:
"He's a guy's-guy, just a dude who happens to be gay. He's a lacrosse player, he's popular. He's after Blaine, obviously, and he's also trying to take the place that Blaine had as the leader of the Warblers. He's been referred to as a villain, which I guess is true in the sense that he's going to get what he wants and he doesn't care who he steps on along the way, but he does so with a smile on his face."
