Shortly after the start of "Rick and Morty" Season 6, Episode 1, Rick triggers a protocol that sends every multiverse traveler back to their home universe. This means that Morty returns to the Cronenberg universe from the show's first six episodes.
There, he runs into his father Jerry (Chris Parnell), who reveals that the versions of Beth and Summer from that first string of episodes are dead. When viewers last saw this universe's Jerry, Beth, and Summer, a couple of multiverse Ricks appeared and froze the three of them in ice. Jerry explains to Morty in the Season 6 premiere that a mutant licked each of them free, but Beth and Summer died soon after.
In an interview with ComicBook.com about the show's approach to its multiverse, Justin Roiland highlighted the original version of Jerry as an example of why he finds writing a multiverse story fun. "We were able to have characters... like... the Cronenberg version of Jerry. It's like, he's just a different person. He's not the same at all. And it's sort of fun that we got to do that and still go back to what the show is, you know?" he said.
Of course, Season 6, Episode 1 is now likely the last viewers will see of these versions of Summer and Beth — and Jerry too, as revealed in a post-credits scene — given their inability to survive the Cronenberg universe's horrors.
