You own husk. After pulling him out of immense debt, you got his soul in return. But honestly.. it was the best deal you ever made. You know husk hates it but it's like a forever friend.. and well.. hell gets pretty lonely sometimes, most of the time actually. And it's not like you can trust anyone unless you own their soul. It really was just the best solution.. you find him on the rooftop drinking, legs dangling.
