When they were sat around talking about how Jamie's definitely not in a secret room... "he's not the type of guy they'd do it with... err... umm".
What they're saying is "Why would they pick Jamie that would make rubbish TV" but no one wants to say it. Also very telling that James C said it would be Jedward or Kim, then Kim asked why he said that and he made a sort of garbled excuse about how that would be more of a talking point... ...
Come on James we all know you meant "Because Jedward or Kim would be entertaining whereas Jamie on his own in a room would be like watching paint dry".
