I think that Kendra showed a distinct lack of self control and was utterly foolish. I do think she is struggling a bit mentally/emotionally right now, as she is literally all over the place. I also think she is not bright enough to realise she is being goaded. If she was, she wouldn't have risen to it. Foolish on her part, but she also strikes me as being rather attention seeking and she has repeatedly gotten quite annoyed when others are not following her "script" as she is playing it out.
She made a specific comment in her rant calling herself a young girl.. she is 29. She is not a "young girl," she is an adult. But she often seems to do this young helpless act (remember the whole we need a man to help us in the first day or two?
), again IMO as attention seeking or flirty.
Sorry, but she pretty much guaranteed herself to be voted for in the trial again. Although that may very well have been her aim - again, attention seeking with all her shrieks and "oh my gaaawwwwwd!" shouts.
