Rachel told Kat to keep out of other people's arguments this morning.
The Thai housemate was upset when she realised that Sara and Darnell had fought because of her attempts to set the Aussie up with Stu.
"Don't try and set people up. Just keep out of it for everyone's sake," Rachel told her friend.
A confused Kat continued trying to get to the bottom of what had caused all the tension, saying: "What's happening in the house? Everyone is arguing. I never argue!"
However, Mikey and Rachel were keen to quell her interest.
"You don't need to know everything that happens in the house. Just keep out of it," Mikey said.
Referring to Kat and Rachel, Darnell said: "It has nothing to do with either of you two at all."
