After dinner, Heavy remarked: "I think everyone who cooks should wash up after themselves."
Renee replied: "We've been saying that for the past 15 days."
Heavy then claimed: "You haven't though, I haven't seen you watch up once, just saying."
"Excuse me?" snapped Renee, as Heavy realised it was then he had made a mistake. "And I'm just saying you probably don't pay attention because I clean up after myself however you on the other hand like to leave a mess."
She went on: "All you're too busy seeing is the f**king food in the table because you are too busy leaving your f**king s**t everywhere."
With Heavy insisting he did clean up Renee told him: "You know what I think you're trying to do, play a game but I'm not going to feed into any more because your opinion means jack s**t."
Heavy said: "If it's not true, why are you so touchy?"
"Because it's an insult!" shouted Renee, "I'm touchy because you insulted me. To say I don't clean up is an insult. I have done for everybody in this f**king house since I have gotten here."
Renee concluded: "And guess what? You can f**king feed yourself now."
