T-Rex: Wait, I had an even better idea! What if reincarnation is real - and we can come back at ANY POINT IN HISTORY?
God: T-REX
T-Rex: No, wait! WHAT IF, dude!!
T-Rex: You could change the present by altering the past!
T-Rex: So if I live one life in a dystopian today, then when I die I can return to an earlier time and prevent that dystopia from taking place!
Dromiceiomimus: But you'd be challenged in the past by reincarnated agents of whoever liked future dystopia!
T-Rex: OH MAN, YES. So dramatic! A fight across time to save all our tomorrows!!
T-Rex: WE'VE ALREADY GOT THE TAGLINE.
Utahraptor: Wait - what if you're the only person who can do this?
T-Rex: Then I win and it's boring, the end!
Utahraptor: No, I mean - what if you're the ONLY PERSON who gets reincarnated? Just you. You keep coming back at different times, and then the big reveal is that EVERY OTHER PERSON WHO EVER LIVED is you on some past or future runthrough! You fall in love with other versions of yourself. Your greatest enemy is... YOU.
T-Rex: I can't tell if this is an amazing idea, or the stupidest idea ever!
T-Rex: *sigh*
T-Rex: ...Sometimes, with the finest ideas, it is truly impossible to tell!!
