MH3 but Deuce ended up in Boston and meets Chad, Clair, and Jackson (who is part monster but in hiding)
Lilith is his antagonist and she comes from a superstitious, monster hunting family. Her father is descended from Abraham van Helsing, and her mother is descended from William Stoughton (the chief judge of the Salem Witch Trials)
She isn’t too bad she just wants balance. The moment she realizes there is a way to get him out of the human world, she stops attacking him and helps.
Ellis is recruited to help too (for the witch drama with Lilith)
Random idea but Frankie’s heart in g3 actually belonged to Ellis’ father
