The Season 4 finale dropped a massive bomb in the form of Space Beth, who’s either the real Beth or a clone sent off into the galaxy to have awesome adventures. Even Rick doesn’t know which one is which, and it led to a ton of tension last season between Rick and the rest of the Smith family. How could he be so callous as to let his daughter go like that? Space Beth didn’t take any malarky from her father either, even causing him to flinch by pretending to punch him.
It’s an intriguing dynamic, and while we get a brief cameo from Space Beth in Season 5, the way she changed the dynamic in the family is never really addressed. She’s just there for a quick beat, and then everyone moves on with their lives as if she never existed. It begs the question if we’ll ever really get a chance to see her again or if she’ll remain on the sidelines for the foreseeable future.
It would be a ton of fun to see her come back to Earth and hang out with the other Beth or even for her to take Beth with her into space. It could make for a real awakening within the other Beth and make her realize that she wants to explore the cosmos, too. At the very least, it would be cool to get some closure on which Beth is the real one.
