I think she did too much too soon. I got bored of it. I only watched them out in the loft, not in bed, but i got bored of it and thought the other housemates dealt with it really well. I'd have been less patient, a LOT less patient.
I think now that she's been so annoying on the first night, it means she'll have to get even worse over the next few days, just to keep the momentum up, and even if she stays in because of it, they'll vote her out the following week. Like people have been stating in this thread, i don't think it's all an act, and the other HM's will think the same, so they'll vote her out next week, and use it as an easy reason for nomination.
