Why do potential returnees expose their alliances?
Graig in season 3 exposed his alliance with the ChopShop. It's not like they turned on him. They were up against eachother and the rest of the house were gonna vote to evict. He was gone regardless.
I can understand Loveita throwing Mitch under the bus. But she must have known Joel was her only supporter in the house and she watched the live feeds and seemed upset about it. Must have known he voted to save her.
And did Kelsey throw Jared and Raul under the bus with who else they were working with or did she keep her mouth shut?
