Of course, Rick has no moral high ground to call an intervention on anyone, given how much of a massive drunk he is. Nevertheless, he arranges a hang with all his friends so they can talk to Mr. Poopybutthole about his drinking problem. This includes Squanchy (who apparently survived the attack on Birdperson’s wedding), Birdperson (who is now a father), Gearhead, and a random neighbor who isn’t an alcoholic.
When Poopybutthole tells them it’s his birthday, Rick turns the intervention into a big party, which quickly gets out of control once Hugh Jackman joins them and encourages Poopybutthole to try and get his wife back. This leads to a fight with Predator, who is now in a relationship with Poopybutthole’s wife. In a fit of rage, Poopybutthole fights Predator, and in the process, scares his young son. In the end, he realizes his mistake and leaves the family, resolving to get better.
“Rick and Morty,” like all sitcoms, is a show that’s slow to change. Like Bojack Horseman once said to an unsuspecting audience at a funeral, “You can’t have happy endings in sitcoms, because if everyone’s happy, the show would be over, and above all else, the show has to keep going.”
Co-creator Dan Harmon has previously said “Rick and Morty” could go on forever. Sure, there are episodes that move the plot forward, or that reveal something big about Rick’s backstory, but even the seemingly biggest character arcs eventually reset (even in small ways). Except when it comes to Mr. Poopybutthole.
