We may yet discover what many have suspected from the beginning — that the astonishingly improbable circumstances of her initial questioning, and what is in practical terms a forged document attributed to her after the fact, will reveal that her testimony, including the built-in lies of age and non-hospitalization, was created before she was auditioned and cast for the role as its presenter.
She's the only one that can pull this off, because of the phone records. The prosecution knows what the physical evidence on record is, and they've told her what she needs to say to stay consistent with that. I also think she's causing them problems because she's not able to remember and stick to the script.
