The fight started after the morning workout, and the Head of House, HOH, Whitemoney, asked all the housemates to clean the house.
Nini was then asked to wash the bathroom moments before Biggie announced that hot water was not available, so most of the housemates were rushing to bathe.
The noise started coming from the bathroom area after Cross started complaining that Nini was washing the bathroom before people shower. For him, he thinks she should have waited for the housemates to shower before cleaning the bathroom.
Cross went to complain to Whitemoney, then Nini asked why he did not complain when other housemates washed the bathroom before the morning shower just as he was doing now.
Then the guy in the midst of the fight went close to her and asked if she did not understand what he was saying and then asked, “are you stupid?”
That was the statement that spilled fuel into the fire, and then pandemonium snuck into the already heated argument.
