1)I remember that werewolves were out in this world and were forbidden to go to school with humans and they couldn't learn math or science. They all lived in special "ghetto" type places and caged themselves during the full moon. Kurt lied and said he was human so he could go to McKinley and he thinks he's sick but actually he's in heat. Karofsky tries to rape him but Blaine intervenes and tries to shoot him with a tranq dart.
I know they went to a McDonalds so Kurt could rub the grease in his hair and not smell like he was in heat. It was originally on the Kurt_Blaine community.
2) Also while I'm thinking of it, there was one on ff.net where Kurt joined Blaine's pack and I'm pretty sure he was turned. There was this part where Kurt ran off during the run and kept pacing the border between Blaine's land and Jesse St. James', even after he turned back. And Jesse said it was fine because Kurt looked familiar but he couldn't remember from where.
