Rima's arrival into the house has added some new life and spark. Terri is now on her own in the kombi van and is more than aware that she's likely to start feel a little isolated.

Terrence comes on the plasma screens to give his farewell message. He lets Terri back into the house after reversing Nobbi's hand grenade. He then tells them that he's taking the hair straighteners off them. Brigitte jumps up and runs to the bathroom to see if they've gone. They're still there so she grabs them but Big Brother sees all and calls her to the diary room to hand them over.

Rima is in the diary room being given the final instructions about her mission. She has to tell them that there is a mole in the house, an imposter, and that they have 3 days to uncover who it is. She is to mess with their minds and try and get them to start looking at each other.

Rima gathers everyone together and tells them that there is an imposter amongst them. They're all shocked and excited to find out who the mole is. And the speculation begins.

Terri is in the diary room and thinks Ben is the mole.

The housemates wonder if it is Terri and want to know if she really has a uterus but she offers to show her scars but no one is interested in looking.

Alice talks to Terri and they both think it's Ben. Rima tells the others in the group that it's obvious when it's pointed out but that it could go under the radar.

Brigitte and Travis burst in on Terri and Alice and scare them to death while they're whispering about the mole.

Ben tells Cherry that he thinks it is Alice but they don't rule Travis out either. Ben thinks the whole thing is going to do his head in. Brigitte comes out and they wonder if it is Rory.

Rory is in the diary room saying that everyone is over analyzing everything in the house. While he's in the diary room, everyone wonders if it is him. Terri tells Brigitte that they're each going to tell Ben it's someone different so they can watch him a little more closely. Terri thinks she's a real detective. Terri and Alice talk about Brigitte who thinks people could easily think it was her due to her ring that she's always wearing. Rory has Alice and Travis on his shortlist.

Ben talks to Terri and wants to know who she thinks but she refuses to tell him.

Alice is in the diary room with a huge grin on her face. She is sure it is Ben. She has a long list of reasons.

Ben enters the diary room and admits that he's likely on many peoples list. He's not going to be able sleep well now that everyone is watching each other with eagle eyes. Outside, Alice is all excited and jumping around telling Brigitte and Cherry that she's adamant that it's Ben.

Rima and Travis return to being good mates and they talk through some of his struggles and events in the house.

Big Brother wakes the housemates up with the usual Monday morning sounds relating to this weeks task. It is cheering crowds. As everyone wakes up, they rub their eyes and ask if Rima is happy to be back.

This weeks task is wrestling. When a housemate hears their theme song, they need to get dressed in costume within 90 seconds and race into the ring and take down the ninja.

Ben is The Prosecutor. Bianca is the Iron Maiden. Brigitte is Blonde-Zilla. Alice is The Determinator. Cherry is Cherry Bomb. Rory is the Roaring Lion. Travis is Captain Possimistic. Terri is Naughty Nanna while Rima is not participating in the task as she is still recovering.

Rory is up first and performs well and finishes off with a signature roar. Terri takes the dummy on in the ring and tells it to get up and fight.

Alice has changed her mind and thinks the mole is a girl because it would be harder for a girl to pull off. Alice and Terri talk and wonder if the mole is in fact Bianca.

The Cherry Bomb is next to take to the ring after Big Brother wakes him from his sleep.

Bianca and Rima talk about the mole and Bianca wonders if it's Brigitte. Rima tells her it is weird knowing who it is.

Big Brother surprises the housemates with a snap nomination. He tells them that they've just entered the final three weeks of Big Brother. Rima is immune from nominations and cannot nominate.

Terri gives 2 points to Bianca and 1 point to Rory. Rory nominates Alice for 2 points and Brigitte for 1 point. Bianca gives 2 points to Terri and 1 point to Alice. Ben gives 2 points to Travis and 1 point to Alice. Cherry nominates Rory for 2 points and Bianca for 1 point. Brigitte gives 2 points to Rory and 1 point to Ben. Alice nominates Bianca for 2 points and Rory for 1 point. Travis give his 2 points to Bianca and 1 point to Rory.

The final tally from the nominations is:

Bianca 7
Rory 7
Alice 4
Terri 2
Travis 2
Brigitte 1
Ben 1

For the second week in a row, Cherry received no nominations.

Alice, Bianca and Rory have the most nominations but Cherry gets to save one of them. Cherry chooses to save Alice because he voted for the other two but when Big Brother tells him he can pick any of them he decides to save Bianca. He then figures he's contradicting himself and goes back to saving Alice.

With Alice out, Terri and Travis are now also up for eviction.

Now get voting
