also as a contribution to angel jakobs. wainwright has grey hair which seem to indicate he had black hair when he was younger. angel has black hair .
listen i know this is flimsy at best bc we have like 2 images of what may or may not be montgomery and he has brown hair for some reason. but to me i know the jakobs genetic traits of autism, black hair, thick eyebrows, queerness and predisposition to addiction are allelles most dominant indeed

funny you mention that because i actually DO have an (albeit messy) sketch of a young, dark haired wainwright with his sister and baby angel.
