Yeah, it is hard to read Kurt there. He seems to move from delight and warm fuzzies to something more like concern or distress. I'm not sure if Blaine started out with the intention of being sad. I would t hink maybe not, since he's usually pretty put together emotionally in public spaces, but this is too much. He may have meant it as a romantic gesture, but it's dredging up all the pain. And I agree with your assessment, that Kurt doesn't know why or what's going on.

Ugh, boys. I was feeling fairly calm about this episode until this song. I'm still fairly certain they won't be breaking up, but it's going to hurt, oh my god.
