The show features several LGBTQ+ characters whose identities are presented incidentally. The son's gay identity is normalized within his family. A lesbian couple is part of the neighborhood's eccentric cast, and a main character's past same-sex relationship is implied. These portrayals are neither central to the main plot nor a source of conflict or degradation, resulting in a neutral overall impact.

The Watcher includes a minor plot point revealing that one character, John Graff, has a child who transitioned. This detail primarily serves to explain John's backstory and the familial trauma caused by his mother's prejudice, rather than exploring the transsexual character's identity directly. The portrayal is incidental, neither affirming nor denigrating.

The series portrays moralistic judgment, often with language rooted in Judeo-Christian concepts of sin and punishment, as a terrifying and invasive force. This is primarily conveyed through the antagonist's letters and the judgmental, hypocritical nature of the community, without any counterbalancing positive depiction.
