Billi and Jonathan hatch a plan

Jonathan and Billi have come up with a plan that they think will cause panic in the house.

Billi told the millionaire businessman that he would pretend to let slip to another housemate that there is a parallel house and that he misses someone in it.

"It's gotta be someone who we can tell to keep it secret, but will tell everyone," said Billi.

They were unsure which housemate would be least likely to keep the 'secret' so they decided to draught in Ziggy for help.

Billi told Jonathan that he informed Big Brother of his plan earlier on in the diary room and Big Brother's only advice was to check the rule book to see if it was against the rules or not.

"I like it a lot. I don't know where it's going, but I like it a lot," said Jonathan.
