[Turk_Diddler]

I don't imagine she went into the house with the plan to grubbily covort under a duvet with one of the idiot males to gain power in the house. She probably imagined just playing on the possibility of it would do the trick and see her get her own way - indeed that's what she appears to have made a career out of. But it wasn't enough, so she's getting desperate, losing perspective, and doing things she'll regret when she leaves the house.
I feel rather sorry for her, that she doesn't feel she has anything more to offer than her rather spoilt body.
