>>125571679...Did you not understand the season finale? The whole gimmick is that out of all infinite parallel universes there is a subset of universes where Rick is the smartest man in the universe. That subset is itself infinite, but smaller than the set of all universes where Rick is smartest plus all universes where he isn't.
My suggestion is that the killer Rick comes from outside the subset, which is where Evil Morty just went.
