If I'm right about this it is a MAJOR spoiler but,
I think we are seeing two distinct timelines/stories. One with White Hat and co. and one with Black Hat and co. My theory is that White Hat becomes Black Hat over the years. 30 years I guess, as that is mentioned in the show. Some of the Hosts are in both timelines because they have always been there since the park opened. Crazy probably, but would be pretty cool........
