The plot of Rick and Morty Season 7 finally gets back to the main narrative loyalists felt it strayed far from. This is none other than Rick Sanchez's (C-137) vendetta against Rick Prime. He wants Rick Prime dead for killing his wife Diane and his daughter Beth, but Rick Prime has been way too smart and evasive. Luckily, Rick gets an unlikely ally in Evil Morty.
