Mortynight Run

"Mortynight Run" is the second episode of the second season of the Adult Swim animated television series Rick and Morty. Written by David Phillips and directed by Dominic Polcino, the episode premiered on August 2, 2015, though it was leaked online beforehand. After dropping Jerry at a daycare purpose-built for alternate universe versions of Jerry, Rick sells a gun to the assassin Krombopulos Michael, but Morty decides to save his target—a telepathic gas-based entity.

The song "Goodbye Moonmen", sung by Jemaine Clement, was later released on The Rick and Morty Soundtrack, while art director James McDermott published some concept art from the episode. Rick picks up rocks that cause a parasite infestation two episodes later, in "Total Rickall", while Morty undergoes character development after choosing to commit murder. On its premiere, an estimated 2.19 million viewers watched the episode, and critics reviewed it positively.
