There's a suspicion Big Brother has been messing with the housemates' heads after a series of unsettling pranks.

Alarms have been going off for no reason, crowd noise has been piped in to the House at random and sprinklers have sent sunbathers scurrying for cover.

Big Brother also got housemates to pack their suitcases, prompting frenzied speculation about a Monday eviction.

Plus they've been asking housemates leading questions about people they'd like to see return to the House.

Most baffled by Big Brother's antics has been Nadia.

After being called to the Diary Room, Big Brother asked her how she was.

"Well," she replied.

The all seeing eye then told her, very sternly, that she could not discuss the conversation with fellow housemates and Big Brother would treat the breaking of this rule very seriously.

"Do you understand?" bellowed Big Brother.

"Yeah," said Nadia, falteringly. "What is going on?"

Nadia was then told she could leave the Diary Room and tottered off in confusion.

Shell spotted something was up and tried to get her to talk. Nadia told her she'd been talking to Big Brother about her mic.

"Do I look like I was born yesterday?" said Shell.

"Leave me alone!" cried Nadia.

But Shell returned later, unable to resist the bait of Nadia trying to keep something from her until Nadia got up to leave and get away from her pestering.

"I'll leave you alone," Shell promised. "I'll just smoke in silence."

Puzzled by her episode in the Diary Room, Nadia returned there to try and clarify what had happened.

"Big Brother is not prepared to discuss the matter," she was told, leaving her more bewildered than ever.

It was then Shell's turn to be summoned for questioning, where she was simply asked who she thinks will go.

It's put the willies up her, and spawned all kinds of conspiracy theories.
