In the lead up to the Veto competition Drew and Cowboy debate what will happen if one of the twins were to be removed from the block. Cowboy continues to think the twins are okay: "My gut is with them, they've got our back if we help them out." For his part, Drew feels it is a huge risk to see one of the twins taken down; he thinks either he or Cowboy will go up if a twin comes off the block. "I'm scared," he says. Cowboy isn't so scared--he thinks that if he gets put up next to a twin, he won't have anything to worry about.

In the lead-up to the Veto competition, Nakomis chooses Marvin as a partner, while Adria chooses Drew and Natalie chooses Cowboy.

THE POWER OF VETO--MUG SHOT

Nakomis is the first to play "Mug Shot," which she characterizes as a tripped-out Science Fiction set. Before her is a jumbo-tron featuring a composite face made up by jumbling the faces of all the HouseGuests. Each of the images is made up of three different HouseGuests, and whoever guesses which three HouseGuests make the image for the entire set of six morphed faces the fastest, wins.

While Diane and Karen chill and watch the competition unfold, Nakomis goes first and seems so freaked out by the images that her concentration is off. Cowboy and Marvin have the most difficulty and record times north of 10 minutes. Adria, committed and competitive, wins the day with a lightning fast 4:41, besting her sister, who is second with a time of 6:43.

ADRIA REMOVES ADRIA

We see Natalie consoling a distraught Adria in bed as they talk about what will transpire. The following day it is time for the ceremony, and when Adria asks Natalie what she would like to do, Nat says, "The Golden Power gives second chances--I would welcome the Veto if it were to be used." Adria listens and then offers her own reasons as to why the Veto should be used on her. "I wish there were two Vetoes but there aren't. Natalie has been reflected by Adria's choices and you don't want to give her a chance this week I don't know when you ever would. I choose to save myself."

Once Adria is done she turns the floor over to Nakomis, who nominates her half-brother, Cowboy, on the basis that he will be safe since the twin will undoubtedly be evicted.

Will Nakomis' plan of putting up Cowboy backfire? Will Adria take revenge swiftly if Natalie is evicted? And how much longer can Drew and Diane keep their relationship alive as fewer and fewer HouseGuests remain? Find out live on BIG BROTHER 5, Thursday night at 8PM, only on CBS.
