Haven

Haven is a child sized doll that Boris found and before joining Louis .  Boris and Tarquin are her adopted fathers, even if they are "exs." They would travel and keep Boris company, more so after Tarquin went missing. Upon getting Boris to work with the exorcist, Haven has been staying with Edith. They work as a housekeeper and security in the home, so no one can snoop into the other's secrets. They secretly love scaring the others, even though they usualy never intend to. It reminds her of how often Tarquin would scare Boris.
