wishyouwould, who was giving spoilers earlier on tumblr just posted this confirmation.
WARNING: The spoiler for prom king & queen is under the cut. Only read it if you seriously don’t mind being spoiled.
I saw Nicole spoiled this last last night, and I can confirm: It’s true. Karofsky wins Prom King and Kurt wins Prom Queen.
And it is meant to be mean. But Kurt takes the moment and kicks its ass. It is a much better moment for Kurt than Karofsky.
I am not going to elaborate on this any more than that, so please do not bother to flood my ask box with questions about it. Hopefully that is enough context to calm people down a little (for those who were concerned).
