2. Audrey tells Jace the whole house plotted against him.
Once Jace was on the block, he decided to go around the house and rally votes in his favor. Some of the Houseguests appeared to sympathize with his situation and said they wouldn't boot him out, but you can't trust appearances, especially on Big Brother.
In a last ditch effort to appeal to James' soft side, he begged the HoH to save him from eviction. Visibly uncomfortable by the situation, James excused himself but that left Audrey with the perfect opportunity to come clean about how everyone in the house knew about the backdoor plan and totally supported it.
We're not totally sure why Audrey would decide to spill the beans to Jace, but, then again, her game play never ceases to amaze.
