The isolation chamber we're calling The White Room is bound to be a strange environment.

Some survive by trying to stay pensive and still – a tactic Luke S has employed since he was unceremoniously shunted into the blank cabin earlier today. Some might get through the experience by jumping into 'happy' mode. Conor's been in that frame of mind for the entire afternoon and evening, laughing and joking, but to be honest that may be more down to the fact that he's not sharing the same four walls as Luke A, Adam and Deana. It's hard to say.

Sara, on the other hand, isn't coping so well. A curious episode occurred this evening where Sara joined in a rambling conversation with the boys and asked what the time was so many times, Big Brother might want to do the right thing and chuck in, at the very least, a sun-dial. Except there's no natural light in there so scratch that.

Luke S discussed, in some depth, whether he and Ashleigh would stick together beyond Big Brother.

"I wonder what time it is," said Sara.

The subject turned to romantic holidays the three have been on – a conversation that was interrupted by Big Brother who telephoned in one of his occasional calls.

"Ask them what time it is!" Sara cried as Conor took the call.

After it was over, talk turned to property deals and how much money could be made from owning a chain of chip shops. Suddenly, entrepreneur Luke S came up with an amazing business brainwave.

"Drive-thru chippies!" he roared, as though this was the defining 'Eureka' moment that would make him his fortune.

"Big Brother – what's the TIME?" screamed Sara, like she'd like to be anywhere, anywhere at all – so long as it wasn't The White Room.

The revelation that Sara's party trick is stripping has not sat comfortably with the housemate whose boyfriend is currently locked in a room with the Scottish siren.

Like Conor before her, Ashleigh, the House team's representative in the White Form task answered "Becky" to the question "Whose party trick is stripping?" When the right answer turned out to be a) beauty queen-shaped and b) banged up in The White Room with Luke S, her response just wouldn't quit...

"I had 110 percent thought it would be Becks."

"Sara was a complete shocker."

"She said she’d sue BB if they got her tits out."

...were amongst Ashleigh's remarks .

She'd be even less happy if she’d known that metres away and moments later Luke S had administered a massage to Sara's fair back. It was a thumping massage rather than a sensual one but still... 

Let's just hope for Lushleigh’s sake that Sara doesn't unleash her party trick in the middle of the night.

As any diligent Big Brother fan is aware, games have been afoot in the House tonight. White Room residents Luke S, Conor and Sara were put through their paces for the 'Space Race', 'The White Form' and 'Hammer Slammer'. 

Then, unbeknownst to the pale three, their pals back in the House were made to perform the very same tasks with the carrot of a luxury shopping budget hanging in the balance.

If the White Team won they would be rewarded while the losing housemates would be saddled with an economy shopping budget – still not too meagre considering there are only six mouths to feed at this late stage in the game.

Anyway, you want us to cut to the chase. We respect your wishes and will abide by them.  A little after Deana, Ashleigh and Adam had performed in the tasks, Big Bro called the housemates to the sofas and the White Room residents to the end of their beds for the reveal.

It was a nail-biting finish. Luke S completed the 'Space Race' task 27 seconds faster than Deana but Ashleigh answered three questions correctly, meaning she was finished ahead of Conor in ‘The White Form’ task. It all rested on Sara vs Adam in the 'Hammer Slammer' task...

Sara did it! In your face, Adam.

As a result the housemates are dining a l'economie while, in the White Room, they're chowing down on their white rewards: fish pie followed by a creamy dessert.
