Blaine/OMC Sadie Hawkins
Hi, I'm looking for a fic where the boy Blaine went to Sadie Hawkins with was left brain dead, and sadly dies during the fic. He still ends up with Kurt, but they take the relationship slow. Blaine's leg was also damaged and has metal in it, so in one scene he's taken aside at an airport to be separately searched.
