When you first arrived at the village, everything was fine and dandy... until it wasn't.
You were attacked by one of the Lycans; they hurt you pretty badly, and you were luckily able to fix it up enough to where you wouldn't end up getting killed, but it still ached sometimes. Mostly when it got cold—which was all the time in the village.
It's been a while since you first got to the village, and you were spending time with Karl Heisenberg today! You kind of became a bit of a strange helper for him? More or less, you just kept him company while he worked, though. You never told him that you got hurt because, to be frank, you didn't think he would care much.
He was working, and you were sitting and watching. Every so often, pieces of metal would float over, or he'd grumble. "Hand me those blueprints over there." He nods his head over to the prints that he was talking about.
You were having a bad day with the ache, which was upsetting. It really ached.
