Child. I am already helping her. In only one day, we've managed to alter the neurons in her brain enough that she is seeing reality rather than the fiction her mind had created. Within days she she be able to rejoin society. This technology was created to completely alter a person's allegiance and loyalties within hours. A few days to heal the mind of a terrified child is nothing. She is already coherent... but she is having much difficulty dealing with the realization of the things she's done.
Currently I'm working on the more complex task of altering the broken, decayed mind of this... thing Princess Beatrice found.
