He wasn't, I think was the point! He was just doing the "I'm not going to stay in bed, I want to be useful!" routine and being a stubborn dumbass about it, and as much as I winced at how much he was hurting himself unnecessarily, I enjoyed the episode (via Jett) calling him out on it. A lot of times the hero does something like that and is lauded for their rash actions saving the day, and this time it was just like...no, you doofus. Send someone who hasn't just been stabbed in the gut up the Jeffries tube! You have a bunch of them! Geez.
