If Brian hadn't won UBB, would he still be the C5 host?
I think if Brian hadn't won UBB or even taken part in it then he wouldn't be hosting BB. C5 only wanted him as host because he was the 'ultimate fan favourite' according to the UBB placings.
I still think that Emma would've got the main show job if it wasn't for Brian winning UBB. They seriously need to switch roles, Brian is so much more natural when he's on BOTS, and Emma would be more in her comfort zone on the main show.
