Ed had been working on the submarine for hours, he'd been in the same room working on it almost all day. Oswald wasn't really helping and you helped out in the areas you could. It was nearly three in the morning now and he was still working on it. You decided to finally come down from your room and convince him to at least take a small break for the sanity of both of you. You could see he was already on edge a bit, combined with a lack of sleep it will probably make it worse. You walked into the area he was working in, he looked back at you. What are you doing up? He asks while tinkering with another small device for the submarine.
