He didn't. Amadeus understood the why of it and gave a nod. It was probably more respect than he himself would have given it considering he would have been at a loss of what to do with it all. Burn it with the body most likely. This was better. This way that last piece of who Alex had been wouldn't be lost.
"Lucky you. First day and you get to help with clean up. Normally we do have cleaners for this sort of thing but considering we need to keep this quiet, well," Amadeus gave a shrug "then I'd have to kill the cleaners and it's so hard to find good help these days. If you keep killing the help then apparently word gets out and no one wants to work for you anymore. Imagine that."
Luckily for them both, Amadeus had a few more tricks up his sleeve that would make the clean up go a little faster and easier. Dealing with blood was what a Tremere was best at after all. It was great for when Amadeus needed to get blood stains out of his clothes. Or shoes that were best not worn to a crime scene.
