I can't recall the title of the fanfic or who wrote it, so I could use some help. John and Roy are riding together somewhere off duty, and someone runs a red light and smashes into them. Roy is hurt more seriously than John. After John regains consciousness, he climbs out to help Roy and help arrives. Even after they are at the hospital, John doesn't tell anyone he is hurt, and worries about Roy. I believe he ends up collapsing in Roy's room. Thanks everyone - it's been driving me crazy!!
