Glee Sneak Peek: Sebastian is Back and He's Not Playing Nice Anymore

Can we all agree that Sebastian is a very, very bad man on Glee? We know that he and the Warblers will be making a return appearance in the upcoming January 31 episode and he's definitely not baring gifts. In fact, he's coming back to deliver some very bad news.

While the Glee gang is hanging around a coffee shop discussing their favorite Michael Jackson moments (to which Rachel shamefully says she doesn't really "get" MJ!), Sebastian pops in for a coffee. Naturally, Kurt is less than pleased to see his arch-nemesis, especially when Sebatian reveals two important pieces of information: (1) he's been chatting with Blaine, and (2) Blaine spilled the details on the glee club's Michael Jackson project. While it looks like McKinley may have hoped to use some MJ songs during Regionals, it turns out that Sebastian has decided to have the Warblers do them as well. And since the Warblers get to perform first as Regionals, there goes McKinley's super set list.

Of course, Kurt and the other glee clubbers are really unhappy about this new development and the part Blaine played in it.
