For Rufus, there was the small matter of a naked body to dispose of. He was no stranger to disposing of bodies, but this time he wanted a method that didn't involve leaving the house.
Rufus's problem was he couldn't leave Tony, who would start to decay and smell to high heaven. Marcus had a chest freezer which could conceivably house the body, but he'd have to empty it first... and he was likely to need the contents to live on for the next few weeks. But Tony could be a source of meat.
'Can't think for this bloody headache!'
