This evening saw the thrilling battle of time travellers Brian and Kara-Louise against BB3 housemates Alex and Adele - as the two teams pitted their not-overly-athletic abilities against each other in the fields of basketball, darts and football keep ups.

But first, the BB3-ers imparted some advice. "You'll have days when you're really good friends with people, and when you're in such a small space like this, you fight over simple things," Alex told them.

"Don't be scared," Adele advised. "It's okay when people boo you. You'll get over it."

First up, was some frantic hoop-shooting, with Kara-Louise and Brian attempting to put Alex and Adele off by singing one of their favourite tunes "BB8 is the place to be..." tunelessly. It seemed to work, as the time travellers were announced as winners of the basketball Task. Yay!

Unfortunately for the time travellers, Alex and Adele won the darts Task with a not-overly-impressive score of 132 and then went on to excel at football keep ups, whilst a dismayed Kara-Louise and Brian looked on.

"Oh no," Kara-Louise despaired, "we've failed!"

"My mates will never speak to me again," added Brian as he struggled to keep his ball in the air. "I won't have any friends! My life's over now!"

"I think we should just give up now!" Kara-Louise giggled, before correcting herself: "You can do it, you can do it Brian! I have faith."

But her faith wasn't rewarded, as they realised they hadn't done as well as they'd hoped and now had to return to 2007.

"Oh, Big Brother!" Kara-Louise sighed, before she and Brian said cheery goodbyes to their new BB friends.

"You guys have been the highlight of my week," Kara-Louise told Alex and Adele.

Come on Kara-Louise - it's only Monday!
