I would have made a few more alterations to Kat to make her different from Catherine but then I thought: why would The Moderator be concerned with altering someone like her? So Kat only has slight differences from her PV proper counterpart the many difference seen are her hair & lack of interaction with a certain duo.

I thought deleting Chad & Ronnie would be a big enough change to alter someone's life but you just can't forget someone like Chad or Ronnie so that's how the dream idea came to be.
