In this timeline, C-137 Rick and Morty end up in a post zombie apocalyptic scenario without any ingredients to help them escape, after running low on plutonic fluids and screwing up the coordinates on Rick's portal gun-which rarely happens. They flee the undead horde with nothing but the basics, abandoning the house, friends, and family, along with whatever was left in Rick's garage that could've helped them after being overrun by dozens of undead abominations.
