?

I realize I started way late with Glee and I swear all I did today was watch season two straight through (can't seem to watch it fast enough). well half anyway --I'm at the episode with the bieber band thing YES! anyway I upendo kurt and it killed my moyo to see him go. yeah they still onyesha him but it's not the same... so my swali is does he come back to new directions??? I have no idea what's going on in the third au forth seasons, so I need to know
