I haven’t gotten super invested in a fan theory since I was in middle school, and I usually just let canon be canon….but that “Rick had a different Morty” theory got me bad.
Well in the first or second episode, his daughter was like “I just got him back in my life and you want to put him in a nursing home?”
Also, rick had proven that if he fucks up too bad, he will just pop into another universe where everything was fine but he died and take his ricks place.
