This is kind of shocking to me -- since I bumped him back down to a junior, I've been trying to set up a little of Blaine's insecurities about Kurt leaving for New York next year, and the fact that he's very afraid that Kurt is going to meet someone more interesting and replace him, but I really didn't expect to see all of that actually confirmed quite so explicitly, it's kind of boggling me. I need to ramp up the insecurity a bit more to get Blaine to the point where he's actually distancing himself, but that should be doable with Genny (and Tina?) in the same boat, and I don't see any reason why we can't keep all of it.
...Man, I'm getting to play all sorts of pissy Blaine here lately, *lol*.
