I have to admit, I didn’t get that understanding at first glance. About the characters having an identity in both worlds (FTL/TEF and our world). I was initially thinking more towards how each character relates to their parents/relatives. Kind of how like some of us have similar facial features as our parents or even how our behaviour is similar. Maybe it’s both, why or why not? Additionally, would there be an actual reason to expand the dimensions any further then it has unraveled thus far???
