I'm afraid, dear cat, that you have been smoking some of that illegal substance again. All doctors who have examined her -- that is ALL, including the parents' doctors -- agree that her brain is gone, dissolved, nonexistent and replaced by spinal fluid. All that is left is her brain stem.
The disagreement -- the only disagreement -- is that the parents' doctors contend -- without an ounce of support in any medical literature anywhere -- that a few of the cells in her brain stem might be able to be trained with enough 'experimental therapy.'

She did not want this.
