I guess despite the main weakness of blindness, Sophia also:
$ Has a fear of losing any more of the 4 senses she has left. %
$ Gets extremely down on herself and shuts down when her blindness directly causes her to fail at something she knows she can accomplish. %
$ Like in the CS she receives partial paralysis from extended use of her powers. %
$ She cannot use her power to sense things through powerful magnetic fields. %
