Answer 1

All I see is a very sad young woman who is desperate for attention.  If I bought her attempt to seem like she is schizophrenic, I'd have to assume she acts the same way at home and a lot more people than her parents would have noticed and insisted on her getting medical care.  She's just one of those kids who think it is their fate to be famous and that that is all that matters in life.  I foresee a very sad decade or two till she grows out of it.

Answer 2

there should be a law against this kind of performance.

Answer 3

Because it isn't really any one's business but the person doing the audition.

Even though this was not real.
