Clearly favouritism from ITV towards Vanessa Bauer, it's been obvious for years but her being the only pro allowed to live with her boyfriend takes the biscuit big time, especially in current times. Much more serious than her simply just getting the young contenders each year, especially when you consider that a few of the pros are married and some have kids (Yebin, Vicky and Mark).
I wonder if she's the reason Alex is gone - perhaps the show saw Alex's rising popularity as a threat to Vanessa's status as their top pro?
