Stu's arrival sparks group paranoia

The arrival of new housemate Stu sent members of the group into a paranoid panic tonight, with some offering conspiracy theories.

Rex kicked off the speculation by insisting that there was no crowd outside, saying: "After an eviction, they play the crowd noise to let the real crowd go home. They're not playing that."

Stu assured him: "There was a crowd, mate."

Mohamed, Bex and Dale joined Rex in the ashtray, where they continued to debate Stu's identity.

"Maybe he's someone's ex. Maybe he's Jen's ex," Bex suggested. "He knew my name and called me Bex. How can he know that?"

Meanwhile, Jennifer and Dennis were under suspicion from the rest of the group after they were called to the Diary Room straight after Stu's arrival.

Lisa said: "I think they're all in on a plan."
