...also I've been thinking that at some point, once shapeshifting is a thing, The Sinner might...create an androgynous form that reflects them, personally? Like, the 'John' and 'Mary' bodies were created to invoke specific reactions in the people around them; I'm talking about a new body specifically designed to be as comfortable as possible for The Sinner.

Mentioning this because it's almost certainly going to bear a faint resemblance to Akoya.
