Kimberly's kind of old news now!
I think we've seen all she has to offer and now she's just waiting around, scheming her way around the housemates and hoping she can last as long as possible with those tactics.
I think she waits for Friday nights to take her weekly reading of public reactions and then lives her following week in the house accordingly.
Also, now we know she's blatantly living a lie in there regarding her romantic status it's kind of exposed her game so she hasn't even got any mystery about her.
Yeah, she a great looking girl who seems relatively smart and seems pleasant enough (unless you're Stephen and she's stringing you along!) but i think that's all there is to her.
