How Big Brother Punished Saga, Nini Over Leaked Secret Task

Recall that Liquorose and Saga during a Diary Session on Tuesday, were instructed to play a prank on their love interests in the house, by picking a fight with them till their next diary session.
Barely a day into the prank, Nini had an explosive clash with fellow housemate, Cross over bathroom cleaning. In order to calm her down, Saga revealed why he had been "giving her attitude" as she had claimed in a confrontation with him earlier in the day.

"Yesterday during the Diary Session, he (Biggie) said there's a task for me, that I should fight with you and not talk to you till the next Diary Session," he said.
He further speculated that Liquorose, who was also avoiding her love interest, Emmanuel, was given the same task during her diary session.

On Thursday, September 16, day 54 of the show, the housemates woke up to the Garden in utter disarray with a letter by Biggie set on a stool.
The letter which was addressed to Saga and Nini, instructed that they both clean up the disarranged room without any help from other housemates.
They are only allowed to go for short bathroom breaks while the punishment lasts. However, at least one person must be in the room at all times till it is cleaned up.
