They might then face challenges from other underworld entities who are not happy with their new - found relationship.

They might start to understand each other on a deeper level as they both deal with the same fundamental aspect of existence. Their love could grow out of a mutual respect for their roles, and they would become a sort of power couple in the realm of the afterlife, with Thanatos handling the physical act of taking souls and Death being more of the overarching concept that he serves.
