Soukou no Strain/Fridge

• Fridge Logic:
  • Sub-light speed, anyone?
  • Being "swept away" in sub-light requires space to be viscous.
  • While oddly named and with slightly-fudged properties, it's fairly clear that "sub-light speed" refers to relativistic speeds.
  • Until the last episode, where consistency goes out the window. (Lead is stranded 100 years in the future, only to be picked up anywhere from 30 seconds to a few days later; her friends have only aged 20 years at the very most.)
