Rodolphus was visiting a potion factory with his father, who had dragged him along because it was "Family’s business" or whatever shit he said in that moment to make Rodolphus shut up. The factory was full of people, animals, plants, elves. You name it, they had it. Who would have thought there was gonna be this much work behind all those potions on the market. He didn't think it was this big. He walked around to explore while his father talked to someone and watched as everyone worked.
