I don't think any of them will.
Bea and Lisa both too hard faced to admit they need to change anything about themselves, they don't see themselves as having done any wrong at all.
Charlie does have a lot of fans out there, he'll be gutted if he doesn't win but he'll get over it.
David isn't bovvered....you must have missed him saying that?
Siavash, Sophie, Rodrigo, all pretty level headed deep down and they are mostly liked anyway, so no worries there!
