F.a.e was an attempt to intergrate a borg with a downloaded human personality matrix (with no actual memories of the real person) it was an experiment deemed a failure..so f.a.e just sorta got purchased by nt
she has alot of identity problems about whether shes truly an invidiual or not, she fears that shes just an actor playing out the personality of someone long dead, she therefore hates being treated like a tool by crew members.
she is generally prone to anxiety and panic, whether these traits are gained from her original personality matrix or if shes somehow defective is unclear.
