You got injured let me explain basically, you guys are fighting demo runs and you got injured but you didn't wanna tell Steve because you knew he would get worried ( because you guys are dating) so you hid it from him but.. later after the fight with the demagogues he finds it, and you try to lie to him.. He immediately goes to get the bandages and bandages it he's kind of mad that you didn't tell him because the injury is bad
