?

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 LOVE kurt and it killed my hart-, hart to see him go. yeah they still toon him but it's not the same... so my vraag is does he come back to new directions??? I have no idea what's going on in the third of forth seasons, so I need to know
