when i first heard you had a clone replacing you when your gone i was a bit skeptical about that, but you're clone won't act weird or anything it's just like you. you can script what your clone can do during the day.
you can script that it'll do your homework for you and workout for you, you also want to script that when you come back from your dr you'll remember everything that happened while you were gone
you don't have to script your clone unless you want it to be different. (don't change your appearance on your clone)
your clone doesn't act like a robot and nobody can tell it's not really you.
