Bodhi gets whacked upside the head during a mission and ends up with a rather serious concussion. Cassian manages to get him to a safe place but the others won't be there for a few hours and he's forced to try to keep his concussed pilot conscious and talking and make sure he doesn't happily slip into a coma before they're rescued.

+Bodhi is pretty loopy and out of it, slurring his words and losing track of time, and he keeps asking Cassian what happened even though Cassian just told him like five minutes ago

++At some point Bodhi starts rambling about his time with Empire and everything they did to him/forced him to do and it's all awful but there's no way to get him to stop talking about it now that he's started

+++Eventually Bodhi loses consciousness and won't wake up again and Cassian very calmly freaks the fuck out
