on the one hand, I think estelle could suffer because some people will see her flipflopping on her feelings on michael, when just 1-2 days ago she was telling BB there's nothing there.
on the other hand, I think estelle could suffer because, if she's making out with someone she doesn't have feelings for, they might see that as being a bit of a hussy - especially when ben and zoe are given so much airtime to accuse her of trying to mack onto every (non-gay) male housemate to date.
but, both judgements are unfair in the context of what's been happening.
firstly, estelle's been isolated. not just BB isolated, but socially isolated in the house - ostracised in particular by her now-kissing partner michael.
which leads to the second point, she hasn't been given the full picture of how he's treated her and just how ugly and hateful his speech and expressed feelings towards her have been for the last 10 weeks.
which leads to the third point, she's been getting drawn in by him. his speech to her tonight in bed was a hard play for a bit of lip action, the flowerly language, the expansive compliments, and not to mention the dogged pursuit for the last week. in most footage, he's the one climbing into her bed or her lounge pod, not vice versa, and he's the one stroking her constantly while she's just spooning.
and as a final point, consider that estelle really is an affectionate person. her first week and a half with ava is testimony to this, and to the fact that she's definitely not male-centric in her affections. coming full circle to the first point, someone with that sort of personality will almost certainly be susceptible to charms at this stage of both the game and her social isolation
