1. Steve being injured because of some reckless behaviour or not taking his own wellbeing into consideration, and the team berating him for it.
2. Steve hiding an injury from his teammates, and them finding out
3. Steve having depression (maybe because of losing everyone he knew after being frozen in the ice, ect.)
And anything else with hurt!Steve and team bonding is fine too. Chaptered fics would be great, but I'm not too fussed about that!
Also, preferably no pairings.
