The doctor is barking up the wrong tree with the BPD rebuttal. But he may have a point with the gunshot through the brain:
Phineas Gage is often referred to as one of the most famous patients in neuroscience. He suffered a traumatic brain injury when an iron rod was driven through his entire skull, destroying much of his frontal lobe. Gage miraculously survived the accident, but was so changed as a result that many of his friends described him as an almost different man entirely.
The Accident
On September 13, 1848, the then 25-year-old Gage was working as the foreman of a crew preparing a railroad bed near Cavendish, Vermont. He was using an iron tamping rod to pack explosive powder into a hole. Unfortunately, the powder detonated, sending the 43 inch long and 1.25 inch diameter rod hurtling upward. The rod penetrated Gage's left cheek, tore through his brain, and exited his skull before reportedly landing some 80 feet away.

Im not saying Little Missy is telling the truth about the order in which she did things. Its probably the opposite of what shes saying. But I go with evidence, and people, apparently, can move - and more - even though they have serious damage to the frontal lobe.
