On BBLB this evening they had a body language expert on and she said that he is basically an introvert.
That's why he's been put in the house, I think, because he's a different type of character to what has gone before. He isn't acting like you expect a 22-year old Big Brother housemate to act and, in my opinion, that's what makes him the most interesting person in the house at the moment.
He's intimidated by some of the outrageous antics by the more attention-seeking housemates at the moment. But he can interact with the others in small groups.
Anyway, I like quiet people.
I've a feeling though that the public might put up the two housemates from the opposite ends of the spectrum for nomination: Jade and Spencer.
Pity.
