In Rick and Morty Season 7, young Morty is looking at life in a brand-new light. He doesn't have to worry about Rick Prime anymore, not after Rick C-137 murdered his evil variant. Now, Morty can enjoy this spiritual freedom and get back to one of his biggest dreams: impressing his peers in high-school. He has tried time and time again, across various realities to do just that, but nothing ever stuck.
