accusing the production of the show you are on of rigging it in someones favor is a good way to get it rigged in anyones favor but yours
This is true. The first rule of Big Brother is do not piss off production and especially Grodner. The second rule is do not come after the chosen one pre jury.
I don't think that Vanessa and Steve will go through with it. Vanessa won't because they won't have the numbers to secure that Jace stays, and Steve won't because hopefully he'll see how much of an ass that Jace is and he wouldn't want to alienate himself
