I know this is a crossover show
Cora is Henry’s grandmother through Regina AND his great-grandmother through Snow.
we are now at FIVE GENERATIONS of drama coexisting with each other
and this is only documenting the relationships of people who’ve fucked, raised from infancy, and (in a few cases) killed each other. If we counted in the people who’ve had romantic tension, are BFFs, or have only TRIED to murder each other, I would need a 3-D mapping program to keep Storybrooke straight.
