The Houseguests completely destroy their party pad.
During the "Hide & Go Veto" competition, the Houseguests were each tasked with burying a POV plaque somewhere stealth inside their abode.
Then, once all of the glossy game cards were concealed, each participant was given two minutes to scavenge through the house and unearth someone else's hidden treasure—and to trash every single room in the process. The person who hid his or her card the best would take home the POV medallion.
Of course, there was a catch. All the cards looked exactly the same, and the Houseguests had no idea who they were booting out of the competition when they returned to the backyard with their locked signs.
More importantly, who the heck is going to clean up this disastrous mess?
