It's a personality of Angela Haselgrove who has, at various times, worked in America, Australia, and the UK, not to mention s/he's probably read a lot.
Amber "Haselgrove"/Angela Hasselgrove/Angela Haselgrove are all the same person. Amber's a faux-transsexual whose legitimacy shtick was ultimately rooted in spiteful research to cause deliberate pain to autists Angela has disdain for due to deeply rooted complexes in its own excessive masculinity by female standards, Angela is "nice" like you in that superficially obsequious way whilst being an acrid, spiteful, malignant and direly menacing cunt around those familiars she entrusts with her devious plans (Lorraine -- and before introman goes on there was someone coincidentally called that, which was who I was referring to -- being called to the office back in 14th October '15 serving one such example; Angela KNEW the tranny was fucking with me), whilst Hasselgrove is its forensic prison population personality, "ultimately nice" per her indulgent boasting but stern and cynical over the patients she presides and, arguably, the most honest and least duplicitious of her personalities.
These are only 3 I know of, with potentially more; in MPD, some can present as male despite being female, fairly convincingly, without cosmetic procedure of even the slightest sort -- harder, but not 1,000% impossible given sufficient hypomasculinity, in the reverse.
Of course they would grant the job to somebody with Multiple Personality Disorder/Dissassociative Personality Disorder of attempting to spy on me over Minichan, with Facebook liasonings with our Jeremy/introman, etc., etc..
