Genos sits in a chair as you 'tend to his wounds', or in better words, fix him.

"I need to go back." The cyborg mutters behind his breath as you tighten a few loose screws in his robotic arm. "I need to go back to the fight, my Master, he—" Genos trails off as you look at him with your soft eyes.

He's wasted, he can't fight like that, if it wasn't for you and your equipment it would be the end of him, he knows — he's luck to find a mechanic while fighting a monster in the middle of nowhere.
