BB9: Day 85 - Lisa and Sara Each Win £25,000

Minutes after the housemates voted Lisa and Sara to face this weeks public vote, the two girls were in the Task Room winning £25,000 each. In a genuine display of sisterhood both Sara and Lisa agreed to share the £50,000 rather than cheat the other one out of the money.

Big Brother set up the Task Room as a game show with the lovable two sum playing 'Prisoners Dilemma' and the housemates glued to the plasma TV screen, watching their every move. Both could have lied but decided to remain true to their word and share the money, but only one housemate can survive eviction tomorrow.

Who goes, YOU decide!

BB9: Day 84 - Lisa and Sara Play Prisoners Dilemma

Lisa and Sara were called to the Task Room and told they were going to have the chance to win £50,000 in a Prisoners Dilemma game. They would have to choose to Take or Share. If both choose Share - they will get £25,000 each. If one Shares and one Takes then the one who picked Take will have £50,000 and the one who picked Share will go with nothing.

As the rest of the housemates looked on as they watched from the TV screen in the Living Area. Lisa and Sara then had one minute to discuss which block they would pick but did not have to tell the truth. Both said they would share within a few seconds.

Lisa and Sara both remained true to their word and chose to share the £50,000, and would leave with £25,000 each. The girls hugged and Lisa gave Sara a piggy back telling the cameras they were both genuine.
