KAREN FINALLY WINS

HoH Marvin and block-sitters Cowboy and Adria choose their playing partners for the Golden Power of Veto Competition. Marvin chooses Drew, "the pretty boy from the Buckeye state," Cowboy chooses his sister, Nakomis, and Adria chooses Karen. It's a choice between Diane and Karen for Adria. And, while Karen is wary about using the Veto on Adria if she wins it, Adria realizes Karen is the safer bet.

Diane, as the Master of Ceremonies for this week's Veto competition, tells everybody to come and get their clothes, which happen to be jumpsuits with names embroidered on the back of them. Drew thinks his orange suit makes him look like a convict.

The HouseGuests enter the backyard to see six giant blocks of ice, and on top of the blocks are water guns for the "Ice, Ice Veto" game. The goal of the competition is to release the Golden Veto, which is embedded in the ice. Then, Diane announces that there is a twist. There is also a red T, and if the HouseGuests get to the T, they have access to a toolbox that might help them free the Golden Veto from the ice. Once they have the Veto in hand, they must then run and hit the buzzer.

The game begins, and after an initial flurry of activity, the competitors run out of water. They begin banging on the very thick block of ice with their very flimsy plastic toy guns with little success. Somebody figures out the pool is an excellent source of water, and everyone (except Drew and Cowboy) refills their weapons to facilitate greater ice destruction. As the competition speeds to its finish, Adria is almost at the T. She thinks that getting the T will help her get to the Veto faster. Karen sees Adria reaching her goal and goes into "use it or lose it" mode. Adria does get the T and fetches a toolbox, while Karen has broken through and can almost grab the Veto with her small hands. Adria busts open the toolbox and starts by throwing a shaker full of salt on the block hoping that will do the trick and melt it quickly. As she continues to try and free her Veto, Karen wriggles her hand into the block, seizes the Veto and runs to the buzzer. She wins the Golden Power of Veto.

Adria makes one last ditch effort to sway Karen, saying that perhaps she can help Karen think through the decision she needs to make. Karen just plays defense all the way. "There are two people on the block who I have nothing against, and there are other people in the House that I have nothing against. I think it's best to leave well enough alone."

Karen later calls the Veto Ceremony to order and offers Cowboy and Adria a chance to speak to save themselves. Adria, who really can't let sleeping dogs lie, says that she has had some interesting commitments in the House, and some people have chosen not to honor those commitments. As she says this, Diane just rolls her eyes and lets out a little sigh. Karen, out of fear and survival instinct, elects not to use the Veto, leaving Adria and Cowboy up on the eviction block.

Will twin number two get the boot, or is Cowboy the next target? Is this the beginning of a Karen winning streak? And what will happen when Will and Natalie collide in the Jury House? Find out Thursday night at 8PM on BIG BROTHER 5.
