Ok so playing on the cryptid thing maybe joseph is an incubus? Mayhaps mary is a succubus and robert unknowingly has befriended a family of sex-devouring demons?

I def need to write some cryptid action and the anon a while back def had something good going with Joseph being a cryptid and fighting with another one and Robert wanting a piece of that. I have to think more on it, but def wanna do something with it
