I wonder if the biologist that had worked at the park, the redhead that was friends with Alex and Crystal, was Stan’s ex. I know it’s so unlikely, but….. it feels like it would make sense. Somehow. Because the world really is a large place but also a small place.

Yeah this was my thought as well. Because “Lucy” did nothing at first, not until the mom died. So perhaps the mom is the one who made them all pay.
