For a show that often loudly professed to hate continuity, canon, and backstory Rick and Morty caps off the first season with an episode that both references characters from earlier in the season and sets up a bunch of characters for future multi-season arcs. Jerry and Beth go off to a Titanic re-enactment experience while Rick and Summer decide to enact the classic Wild Teen Party with much of the humor coming from Morty being the straight man trying in vain to keep the house from being trashed. References to earlier in the season include some stair goblins, the flu hating rapper, and some Ricks from the Citadel of Ricks (a parody of John Hickman’s Council of Reeds). Seemingly throwaway characters that become important characters throughout future seasons include Birdman, Tammy, Squanchy, Gearhead, and Slow Mobius.
