I've been wondering if I should continue writing Flip the Switch because I've been getting kinda lazy lately. So, I had an idea based on a random thought. I'm gonna change it up a bit later on if I keep writing it. Maybe then I'll get motivated...
If this world was multidimensional, allowing one version of yourself to be in each universe, what if having a twin is just a problem in whatever system the universe derives on that causes one of the versions of you, from another world, to get sent to this world but at a later time. Which causes the little gap of time separating them and their twin?
