"Not What He Seems (aka The Return of Stan)" is the 11th episode in the second season of Gravity Falls, and the 31st episode overall. The episode also serves as the mid-season finale of season 2.[3]

Official overview

After agents Powers and Trigger take Stan into custody, Dipper and Mabel begin to wonder how much they actually know about their Grunkle Stan![1]


The episode opens with Stan working on the machine. He rigs up some drums with toxic chemicals, as he exclaims how he does not care how dangerous it is. He sets off a timer, and syncs it up with another one on his wrist. A side effect of the machine is temporary gravity anomalies.

Stan arrested.

The next day Mabel shows Dipper a closet full of fireworks. Stan invites them to set them off on the roof. A heavily armored operator proceeds to tackle him, and Agent Trigger comes up behind him to signal the rest of the tactical team to secure the Shack. Worried and perplexed, Dipper and Mabel inquire what is happening, before they notice Agent Powers and Trigger, whom they thought had been eaten by zombies. The agents tell the children that an unknown person stole toxic chemicals the night before, and they suspect that the culprit is Stan. They then proceed to put Stan in their car, sending him away to be interrogated. They also take Dipper and Mabel, and inform them that they'll be going to child services.

Stan escapes custody.

Dipper and Mabel decide to clear Stan's name by finding the security tapes from the night before. They force Trigger's car off the road, break out, and head back to the shack. The agents try to interrogate Stan, but Stan insists on his one phone call. Stan uses it to talk to Soos through the walky-talky in his car. He tells him to guard the vending machine with his life. Dipper and Mabel return to the Mystery Shack, and after Dipper nixes Mabel's aggressive initial plan to attack the security forces guarding the front entrance, use Mabel's grappling hook to sneak into the attic. They find the security tapes in Stan's office, and review the footage. They are able to find video surveillance of Stan restocking the shelves. Seemingly proven innocent, they start to celebrate, when Stan suddenly leaves the shack. They fast forward the footage to see that several hours later, Stan, in full hazmat gear, is the one that stole the chemicals.

What is going on?!

After realizing the truth, they find a hidden box in the office full of fake IDs and passports, as well as a newspaper clipping with a headline saying "Stan Pines Dead." Another clipping has a picture of Stan with a caption identifying him as an unnamed grifter. Mabel and Dipper, now totally unsure if Stan is really who they think he is, find a paper with the combination to the vending machine door inside the box. Meanwhile Stan manages to escape the agents by using a gravity anomaly being generated by the machine. After exiting the building, Stan misleads the agents hot in his pursuit by using the cash stolen from an agent's wallet to pay a taxi cab driver to act as a diversion and drive his cab as far away as possible from the Mystery Shack.

When government forces pull out of the Shack to assist in the search for Stan, the way to the vending machine is now clear. The twins head down to punch in the code, when they are stopped by Soos, who's been ordered by Stan to hold the vending machine, with his life if necessary. After a brief struggle, Dipper finally manages to input the code, revealing the secret bunker under the Shack. Inside Mabel, Dipper, and Soos find Stan's secret lab. Dipper, upon discovering the first two journals, is enraged at the fact that Stan has been hiding them and lying to them all summer. He puts the books together to form the blueprints of the machine. He uses his black light to reveal a hidden message by the author. They find out that, if the machine is activated, the entire universe could be destroyed. Dipper then finds out how engage the manual override.

Mabel doesn't know what to believe.

Right when they're about to hit the override button, Stan shows up begging them not to push it and saying that he will explain. Dipper refuses to believe him, and then another gravity anomaly occurs, lifting everyone up into the air. Mabel makes it to the shut off button, with Dipper telling her not to trust Stan and push it. Stan begs Mabel to trust him, and attempts to approach her only to be restrained by Dipper and Soos. After another fluctuation pins them against a wall, Stan begs her again to not press the button, asking her if she really believes he's a bad guy. Mabel cries at the decision she has to make. Finally, Mabel tearfully decides to trust him and lets herself float away from the override, much to Dipper's dismay. 

S2e11 author revealed

The author revealed.

After the device activates, what seems like an explosion occurs and nearly destroys everything in the shack. When the light fades, the anomaly shuts down, with everyone seemingly okay, including the main characters. With the portal still functioning amidst the wreckage of the lab, a mysterious man with a rifle over his back walks out of the portal. He places his hand on the first journal, revealing that he is in fact the six-fingered man implied to be the author of the journals. Stan reveals that he is the author of the journals. The man removes his hood to reveal he is Stan's long lost brother. Mabel asks if someone should be fainting, then Soos replies that he'll faint and proceeds to do so.

In the end credits Stanford and his brother as children are quietly swinging on Glass Shard Beach as the sun sets.

The Mystery of Gravity Falls countdown

The countdown.

  • A countdown leading to this episode could be viewed at the fansite The Mystery of Gravity Falls, which was supported by Hirsch.[5]
    • However, due to the website's author not accounting Daylight Savings Time, the countdown was off by an hour.
    • After the countdown finished, it was replaced with the image from "Ker-Prank'd," a gag in this episode.
  • A page in Journal 1 suggests that the giant fissures in the cliffs of Gravity Falls aren't naturally occurring. 
  • According to the countdown for the portal, its anomaly pattern seems uncertain, but occurs at a time when the minute and/or second reaches zero, although not for all possible times.
  • As with the rest of the series, certain scenes are animated specifically in the United States, rather than overseas in Korea. The scene in which the author was revealed was animated by Dana Terrace, although the keyframes were done by Matt Braly.[6]
  • Alex Hirsch gave the script of this episode to the winner of a Gravity Falls Toys video contest. [7]
  • Alex Hirsch confirmed the identity of the author had been planned since the show was initially pitched to Disney.[3]
  • In the UK, the TV guide refers to this episode as "The Return of Stan," but this was a mistake and is not the actual title of the episode in the UK.[8]

  • In the code on the countdown website, the cryptogram "GRQ'W FRSB WKDW IORSSB" can be seen, which decodes to "DON'T COPY THAT FLOPPY." This seems to be a request to not duplicate the countdown website's code, as it refers to an anti-piracy PSA.[9]
  • In the promotional video entitled "Gravity Falls Police Station Audio: Grunkle Stan Discovers Something Cryptic (Part 3 of 3) has Stan discovering a message saying "JLGHRQ KHUH," which decodes to "GIDEON HERE."
  • In the cold open, a page in journal #1 on the topic of floating hills has a symbol cipher that says, "Symbol cipher - MSymbol cipher - YSymbol cipher - SpaceSymbol cipher - CSymbol cipher - OSymbol cipher - MSymbol cipher - PSymbol cipher - ASymbol cipher - SSymbol cipher - SSymbol cipher - SpaceSymbol cipher - GSymbol cipher - OSymbol cipher - ESymbol cipher - SSymbol cipher - SpaceSymbol cipher - HSymbol cipher - ASymbol cipher - YSymbol cipher - WSymbol cipher - ISymbol cipher - RSymbol cipher - ESymbol cipher - Space Symbol cipher - TSymbol cipher - HSymbol cipher - ESymbol cipher - SpaceSymbol cipher - CSymbol cipher - LSymbol cipher - OSymbol cipher - SSymbol cipher - ESymbol cipher - RSymbol cipher - Space17pxSymbol cipher - ESymbol cipher - TSymbol cipher - SpaceSymbol cipher - TSymbol cipher - OSymbol cipher - SpaceSymbol cipher - TSymbol cipher - HSymbol cipher - ESymbol cipher - MSymbol cipher - Space Symbol cipher - DSymbol cipher - OSymbol cipher - ESymbol cipher - SSymbol cipher - SpaceSymbol cipher - TSymbol cipher - HSymbol cipher - ISymbol cipher - SSymbol cipher - SpaceSymbol cipher - MSymbol cipher - ESymbol cipher - ASymbol cipher - NSymbol cipher - SpaceSymbol cipher - WSymbol cipher - HSymbol cipher - ASymbol cipher - TSymbol cipher - Space Symbol cipher - ISymbol cipher - SpaceSymbol cipher - TSymbol cipher - HSymbol cipher - ISymbol cipher - NSymbol cipher - KSymbol cipher - SpaceSymbol cipher - ISymbol cipher - TSymbol cipher - SpaceSymbol cipher - DSymbol cipher - OSymbol cipher - ESymbol cipher - S: Symbol cipher - SpaceSymbol cipher - TSymbol cipher - HSymbol cipher - ESymbol cipher - SpaceSymbol cipher - ASymbol cipher - NSymbol cipher - SSymbol cipher - WSymbol cipher - ESymbol cipher - RSymbol cipher - SpaceSymbol cipher - MSymbol cipher - ASymbol cipher - YSymbol cipher - Space Symbol cipher - BSymbol cipher - ESymbol cipher - SpaceSymbol cipher - USymbol cipher - NSymbol cipher - DSymbol cipher - ESymbol cipher - RSymbol cipher - GSymbol cipher - RSymbol cipher - OSymbol cipher - USymbol cipher - NSymbol cipher - D."
