Darcy is injured (broken leg/pelvis, something affecting her mobility) and its decided she needs to go into hiding to avoid Hydra/big bad (not sure who it was). Steve and Bucky are tasked with taking care of her, and they are a bit resentful of being taken away from the 'real' action. At some point I think Clint yells at them for not taking good care of her.
There's a road trip, some cow taunting, and they finally end up at an underground safe house. The ventilation is messed up, so its freezing cold.
Eventually the fight comes to them and I think there was a fight on a train, falling off the train?
Its been a while, so I don't recall if it was Darcy/Steve/Bucky, but I kind of think it was?
Any help you can give me would be appreciated. Tagging with possible tags.
