The Wubba Lubba Dub Dub of Wall Street, Part 3
Morty barges into the dining room and accosts his parents for having a garage sale of Rick's things. He is acting strangely, as he keeps referring to his dad as "Jerry". He then charges out in frustration and enters his room, where another Morty is tied up in bedsheets. Jerry notes that Morty is acting strange, whereas Beth just thinks Morty is feeling guilty that he got out of the labyrinth and Rick didn't.
In the labyrinth, Rick has enlisted the help of a buff dude to help him retrieve a battery to fix a transporter. Just then, alien spiders attack and Rick presses the guy to find out why he was sentenced to the labyrinth. Once Rick hears that the guy ran a school bus off the rode while super drunk he has no problem sacrificing the guy to make his getaway.
Back at home, Beth hates that she has let herself stoop so low as to be cleaning Jerry's bachelor pad basement while he is off golfing. The alien thing that Jerry had inadvertently let loose in the house latches onto Beth.
Upstairs, Summer comes home and finds Morty waiting for her in the dark. He attacks and she rushes to Morty's room and closes the door behind her. She finds the other Morty wrapped up but then hears her mother's voice outside the door pleading for her help, as there is something wrong with Morty. Summer opens the door and is attached by Beth. Summer pushes her mother down the stairs and kills her. Odd Morty shows up with a crowbar but is unable to attack because Rick shows up and melts the Morty with his gun. He then stuns Summer and marches upstairs.
Jerry comes home to find Beth dead, Summer unconscious, and a melted puddle of blood in his living room.
Adventure to an Alternate Universe
