Dont be fooled by the naive character she is showing, she is sly she is a backstabber as illustrated perfectly last week with her yay for marcus performance and less than a week later hating him again.
Shows a complete false character, and she changes more than the weather it seems to be whoever is sopported the most in that particular week she is there.
Remember how much she hated halfwit for weeks yet as soon as lisa and karly started to offer the olive branch because they realised he was popular outside she was immediately a fan.
NOw the thing with marcus cuddling him on the couch and the marcus campaign and now finding people to rubbish him to.
That bit they just showed of her in the bathroom illustrated how sly she is, she went in and started immediately going on about marcus hoping david would start a rant and when he agreed she was in her element then going on about his clothes etc
Does she forget that through her obsession for alcohol marcus offered her his cans and she agreed in return to do his washing, she conveniently forgets this though and starts on him.
My message to her is drink less, scratch your head less and backstab less

thats a good start.
