Meet Glee’s Season 3 Villain: Grant Gustin Is New Warbler, Sebastian [PHOTOS]

Oh, Grant Gustin: We want to like you. We really do! You’re super cute, totally charming, and you’ve got a great singing voice. Unfortunately, your character — Sebastian — is a scheming little troublemaker who is bound and determined to break up our precious Klaine. What? We see the way he’s looking at Blaine (Darren Criss) during “Uptown Girl.” Not cool, dude. So not cool!
