For the first time in the history of 'Big Brother', the housemates have been allowed to discuss nominations with each other.
In the latest development on the show, the four housemates living in 'Heaven' - Stuart, Rex, Mikey and Mohamed - were given access to a fuel pod in the garden where they could plot nominations.
Only two of the quartet could enter the pod at whatever time and they were forbidden to talk about anything simply nominations.
The tetrad decided to nominate Dale, Luke and Darnell this week.
The odds on Kathreya winning the show hold lengthened from 15/8 to 2/1.
Commenting, Ladbrokes spokesman Nick Weinberg said: "The cookie monster's world is crumbling all round her. She's friendless and is a vulnerable favourite."
