Allan has a good point. IF Byrne AF returns then Aurora should be in a mental hospice first to try and get 'fixed' while AF leaves her alone. Only Sasquatch and Shaman have any medical experience that could help her. From my experience with mental disorders (autism, MPD, schizoid, sociopath, psychopath) I found MPD and psychotics the hardest to help, so much is biological and retraining to cope can't be done without years of intense training. No reason Aurora would be easier, she'd be harder.
In an Ultimate AF setting she could start out healthy but slowly turn MPD as the pressures of being a hero get to her, with the resultant running from battle, Northstar going after her etc. problems.
