In "Advent Children", they make reference to "Jenova's memetic legacy". I had been meaning to look up memetic, but just now did because, being drunk off my ass, I need all the help I can get.
There was no "memetic" at Dictionary.com, but MImetic makes perfect sense in the context. Jenova's mimics.
Yeah. That. I can run with that. Makes absolute, complete sense once you've played FF VII.
