Reposting here now that I'm somewhat awake.
Once the heir is born, can we cure the occult partner of their occultness? Such as a vampire getting the cure from the science facility, or asking a fairy to forsake the fae? I haven't started yet, but I'd like the partners/spouses to die in the family, and I can think of at least 4 occults that have long lifespans (vampire, fairy, genie, werewolf).
