Cain only grabs the essentials, reveling in the chance to resupply inside what is essentially a dungeon, since he doesn't actually need much. A fresh pickaxe, travel food rations, a small cask of whiskey.
As thanks for going all out during the examination and making him a master-crafted ax; Red puts him up for the night in his own home, a large stone building whose occupants make Cain's Guild look calm and rational. The giant Dwarf has fifteen children of his own and lives on a family estate with his parents, six brothers, plus all their wives and children.
Even the orphanage wasn't this chaotic. Red's family is far from wealthy, but they're very lively. Cain is pretty sure he has answered enough questions from the adolescent dwarves to successfully solve the meaning of life by the time he sets off the following day.
