Sean Elliot asked Erika Johansen:

This question contains spoilers… (view spoiler)

Erika Johansen Hi Sean. I think someone asked this same question a few years back, and as I said there, my grasp of physics (especially as pertains to time travel) is essentially nil. My idea at the time was that Kelsea's actions would have caused two diverging realities to go forward from Year 20 in the Town, but even if you're a one-timeline wipe-out-the-past kind of person, I still thought I had the right to go back to a point which did once exist before Kelsea's life and write about what happened "before" she ever took any action. Einstein would surely slap me for it, but I couldn't care less if I think I have a good story to tell.

Hope that helps, and thanks for reading. I hope you liked BTK in the end.
