The housemates are up late doing the House of Horrors task.

1) Bea is upset because she's got some green make-up in her skin, and goes to see Big Brother about it.

Lisa and Charlie compare drama queen Bea to Nikki from Big Brother 7. Lisa said that Nikki is different in that she likes her friends.

Sophie and Siavash tease Marcus about his graveyard shifts.

As they're cooking some food to eat, Siavash suggests they fail the shopping task so they don't have another luxury budget, as they're eating too much food, and putting on weight.

2) Bea is no longer upset as she is in bed tucking into biscuits. Charlie comes in and he asks her to put some drops in his eye.

Whenever they hear the sound of a train played into the house by Big Brother, they all have to walk about like zombies, making moaning sounds, until the sound stops.

As it's now past midnight, Big Brother won't play the sound outside so as not to disturb the neighbours.

Charlie tells Bea he'll be heartbroken if she goes on Friday, and he can have a laugh with her, as he can with David and Marcus.

3) Bea's moaning that she may not have a job again. David tells her "Don't worry, be happy". Charlie reckons that it'll be hard for them to get jobs, but it may be okay for models like Kris and Sophie.

David says he likes this task but doesn't want rats involved, and Lisa teases him about it.

Lisa is reminded about the pigs eyeballs she ate, and said she preferred it to licking a man's genitals.

The train sound is played into the house again and the housemates become rezombified.

4) Lisa and Siavash discuss their survival in the house, and past housemates.

The train sound sounds again and the housemates zombie about for a bit.

Siavash is thankful it's not a 24 hour task.

Lisa and Siavash got back to discussing past housemates, and he guesses that Karly probably has had a boob job by now. He also wonders what his friend Cairon is up to, and they wonder how long Beinazir and Saffia would have lasted.

He also reckons it was good when the newcomers came.

They try to guess who will go on Friday, and Siavash guesses it could be between David and Bea, but it's very hard to guess what the public is thinking.

Siavash says it's weird without Freddie in the house, and that he can barely remember him being in the house.

5) Bea says her life was sorted before Big Brother, and she's starting to wish she'd never come on the show, as she's getting paranoid.

A sound is played into the house signalling that Siavash and Lisa do their part of the task. They must change into howling werewolves.

6) Marcus talks about selling stuff on eBay and making lots of money as it's Big Brother related, and he jokes with Bea that if he gets £2 million, for an item, he'll give her £1 million.

Bea is still worried about money and thinks one option is to get married.

7) David is still talking about his dislike for rats (probably a sure fire way of making sure rats are included in his part of the task), so he Bea, Siavash and Lisa talk about rats, mice, sickness brought on by rat urine.

Siavash said he used to have a white rat with red eyes. Bea suggested it was an albino rat, and made a veiled reference to Darnell in last years series.

Lisa tells David she's surprised he's nominated for eviction, and he says he's not bothered and it's his chance to get glammed up, and wear every bit of Vivian Westwood he's got in the house, and he's excited about it.

8) David and Lisa discuss Bea's nomination of David, and the conflicting signals she gives off.

Siavash and Lisa do their werewolf change routine again, and they strike some amusing poses as they howl.

Bea plans to scare Siavash with fake spider dangling from a thread.

After Siavash does a little gangster rap, Charlie tells him that he's the most gangster person he knows. Bea agrees with him, and Siavash is very pleased by the compliment.

Bea follows it up with "Not very gangster, but the most gangster person I know", which took the shine off it a little.

9) Bea and Charlie tells Siavash that his personal hygiene is a little off. At the same time Bea tells him that he's a fine figure of a man and says to him if he ever gets lonely to let her know. and winks at him.

Then she says she can smell him from where she is.

When Siavash goes for a shower, Bea sets up the fake spider on a thread hanging from a microphone.

Aided by Charlie, she puts talcum powder on his pillow.

10) Bea and Charlie wait for the trap to be sprung.

Lisa is pleased with the werewolf poses she pulled and tell the others about it.

She also says she wouldn't find the prank amusing, but they're sure Siavash will find it amusing.

However Siavash goes to bed and seems not to notice anything amiss.

Charlie asks him about his part in the task, which he answers, still settling down for the night, unaware of the prank.

11) Charlie and Bea go to the kitchen and try to think up more pranks they can do, and are considering using fake blood.
