Paul then asks what happened to the man's hands, and Carl reveals that he cut off the man's hands, prior to his demise, cooked and ate them because apparently, his stomach was "making to rumblies that only hands could satisfy".
In the second episode of Llamas with Hats, Paul is on a lifeboat with Carl in the middle of the ocean, with a sinking cruise ship behind them. It is revealed that it was Carl who sank the cruise ship. When Paul asks why the lifeboat is red and sticky, Carl reluctantly tells him that he murdered the elderly couple from 2B.
Carl and Paul are on vacation, with a burning civilization behind him. It becomes quickly apparent that Carl toppled the South American government, which is burning behind him. He claims that it was in the name of the resistance, but Paul points that Carl pushed the resistance leader into a giant fan.

Paul is scolding Carl because has left a trail of muddy hoof prints on the carpet. As the llamas are arguing, and Carl is insisting that the culprit of the muddy tracks is not him, but a phantom, the entire back wall of the home explodes, revealing that the city has been hit with a nuclear bomb, and Carl wishes Paul a happy birthday.
Paul says that it isn't funny anymore and that it isn't even his birthday, but Carl tells him that they now have lots of roasted faces to eat. Paul says that he doesn't want to eat faces and Carl admits that he probably won't like his birthday decorations, at which point, balloons with severed faces attached to them begin to float towards Paul.
Since the events of Episode 4, Paul is not surprised by Paul's actions anymore. However, Paul seems to also have become paranoid, and always suspects the worst of Carl. After listing a bunch of seemingly harmless things he did during the day (including washing the car and baking a loaf of banana bread for their next-door neighbor), it is revealed that Carl created a crack in spacetime to collect millions of baby hands. Paul, however, does not seem impressed, thinking of it as anticlimactic by comparison to Carl's previous escapade with the nuke and the burning faces, despite Carl's attempts to convince him that it's "totally fucked".Mrs. Bigsby with her garden because he ended up burying her alive.

Carl visits Paul's new home with the hopes of reconciling, only to reveal that because of the mask of Paul's face that Carl has been using, Paul is now a wanted criminal, believed by authorities to be in charge of a Russian opium cartel. Paul tells Carl to go away because he has given him "enough chances" and that he'll call the police.
A "swan piano" then crashes into Paul's house, which Carl made with the intent to send to Paul as an apology gift, but his plan backfires and Paul just gets angrier.
Near the end of the episode, Carl tells the Paul mask (who became sentient in the later episodes of the series) that he is going to find the real Paul.
Carl returns to Paul's house, the one seen in episode 8, shouting his name. When Paul doesn't answer, Carl walks into the house, saying that he is sorry if it violates his restraining order. When he enters the house, however, he finds that Paul has died and is now nothing but a skeleton.
