What are the chances Brandon actually does something smart for a change? Try this on for size:Armed with the knowledge that Andrea is out to undermine Corinne before Corinne can undermine Andrea, Brandon seizes the opportunity to shatter Stealth. He goes to Corinne and Malcolm and reveals what Andrea has been doing. Corinne and Malcolm believe him and/or confirm it somehow, and join in a plan to take out Andrea, depower Phillip. With Brenda and Erik also non-Stealth along for the vote they have five, and Malcolm doesn't even have to worry about playing his idol to cover Corinne.
What goes wrong?
Brenda really wants nothing to do with Brandon, they are allies simply out of having been excluded from Stealth. Brenda reveals Brandon's plan to Phillip and Andrea, joins Stealth, she's in the power alliance. And they target Corinne, which is what Andrea wants and it breaks up a pair. Brenda, the new and improved Dominatrix.
Possibly Erik also seizes this opportunity to join Stealth, but that seems less likely.
After Corinne is voted out they return to camp and Brandon Hulks out.
