I'm in a foul mood and I'd like to distract myself. Does anyone want to talk about Grey's season finale? I know it aired some time ago but I just remembered I never discussed it with anyone.

SPOILERS AHEAD

Does anyone find the Callie and Arizona development completely unrealistic? It felt like an add-on to me, because Rhimes needed some drama but had exhausted her "tragic death" folder. They'd been re-building their relationship the whole season and it looked like it worked and then it's the damn leg again. Plus the random chick who was randomly very much into Arizona and she into her for no reason at all. I mean, motivation? Something?
