Other important context is her past performances [0]. Rhythm 0 is the last of five performances in which she injured herself, intentionally lost consciousness, and took medications that gave her seizures. In one of the performances a sympathetic audience came to her rescue when she fell unconscious, so she performed the next one alone with a cameraman who was instructed not to intervene. Once again, in contrast to the picture of humanity she seemed determined to paint, he intervened anyway.

Given that history, I sure wouldn't have shown up for Rhythm 0, and I don't know many decent people who would have either.
