This evening's episode saw tensions between the housemates reach boiling point as soon as the group wake up.
Deborah was unhappy, as her clothes have been made dirty during last night’s chocolate fight. Later, Deborah's sister Hannah discovered a plastic mouse has been left on her bed.
Lotan admitted to the practical joke, but Hannah, Deborah, Isabelle and Raph didn’t see the funny side, leading to the house arguing over the plastic mouse.
Deborah then discovered there was water in her bed and it caused more tension, as Raph told Hannah and Chanelle about it. Kieran insisted to the sisters that it was an accident.
In revenge, Chanelle and Isabelle played a prank on the house by putting ketchup and sun tan lotion on the floor of the kitchen.
Chanelle and Isabelle cleaned up the mess in the kitchen, whilst Joe and Lotan discussed them in Rose Cottage, with Lotan calling Isabelle “boring” with “no purpose”.
Lotan and Chanelle then had a huge argument in Thorn Cottage but the night didn't finish there.
Isabelle then stuck up for Chanelle in a row with Lotan and as far as most viewers (including us) were concerned, won the war.
Their argument ended with a frustrated Lotan storming off and fans couldn't be happier.
