Steven Walker's unit liberated Talia and helped connect her to Stormwatch.  Stormwatch helped unbrainwash her and connect her with the resources to undo the face lift, etc. that was done.  She kept in contact with Stormwatch out of fear of being kidnapped again, but never joined.  Steven Walker was a regular Joe when he helped Talia and was Black Ops, but not Stormwatch.  After Walker becomes a cyborg, Talia repays the favor by helping to bust him out of where ever he was (likely with Stormwatch's help), but was not a member of Stormwatch herself and I do not believe American Psycho joined a team until The Authority formed.  We did agree that it was Talia who suggested American Psycho to be brought onto The Authority team.<br/><br/>That's about all I know.
