Kurt and Blaine are in a car crash, it's mostly told from Blaine's POV. He's flashing in and out of the present, flashing back to their past- I know there was something about tickets to Wicked. and there was a line to Burt about Blaine will take care of him. There was also mention of promise rings.
in between, he flashes to the present, in the hospital. In the end, he comes to, Burt's in the room, kurt is next to him, already dead, and Blaine says something along the lines of 'I've got him" and then something about "going into Kurt's waiting arms". It was really heartbreaking, beautifully written..and I've lost it! Hope someone knows that I'm talking about!
