"First off, I said it was POSSIBLE that I killed SOME of them." Zmerr looked at him through slitted eyes. "Most of my kills are male because they're meatier. Anyways. As for that burn, I do apologize. But perhaps you should have considered that you might get hurt BEFOR'E you trespassed in my home. That one you brought completely on yourself." He motioned for the golem to come to him. "Fetch me the first aid kit. He looked back at the man. "We didn't really strike a deal anyways. I said I was coming by tomorrow to finish sorting it out. There was never a definite agreement for me to do any work." 
When the golem returned with the kit, Zmerr came to kneel beside the man. He pulled out a sort of cream and began rubbing it on the burn. "It'll hurt right away, but it'll make the burn heal faster." When he felt that the cream was sufficiently spread on the man's burn, he wrapped it up.
"I don't believe i've ever caught your name. It may not matter for her, but if I'm going to be doing anything for you, I will need to know."
