Gravity Falls: The Final Chapter

Gravity Falls: Return to the Falls is a Disney XD movie based on the popular animated tv show Gravity Falls and was released in the summer of 2018

The Plot
The movie is set several years after the events of the finale and Dipper and Mabel are now nineteen years old and are both returning to Gravity Falls for the summer. Stan and Ford have both returned to the shack where they have been employed by Soos to run the shack alongside him as co-owners. After the first few weeks of living in the shack, Stan tells Ford that he had been getting hallucinations of Bill Cipher and Ford creates a machine so that he, Dipper and Mabel can see into Stan's mind. The trio makes the horrifying discovery that Bill has managed to resurrect himself with a spell and has managed to implant fragments of himself into a new employee of the Mystery Shack named Lewis.

Once Bill has been able to possess Lewis; Bill plans to meet the elder gods, beings who existed before the creation of the universe and Bill plans to convince them to destroy the universe, so a new one can be born and a new cycle of life can begin.

It's up to Dipper, Mabel, Wendy, Soos, Stan, and Ford to stop Bill and save their very existence.

Mabel's subplot
Since Dipper and Mabel have both finished College, Dipper and Mabel are stuck in what choices they should make in the future, Dipper was given an opportunity to attend Yale in Connecticut whereas Mabel wants to start work as an artist and performer in Broadway, and she and Dipper both wanted to use this summer as a farewell to their friends. As the movie progresses, Mabel loses motivation towards Broadway because of how difficult it is for her to move forward and take risks.

Dipper's subplot
Before the events of the movie, Dipper decides to use this summer to date Wendy after she tells him that they can date since they are at a point where the age difference is no longer a problem. When he arrives in Gravity Falls, he develops a crush on Pacifica and becomes confused on who he would like to be with; Pacifica Northwest who shares a mutual crush with him but is afraid to tell him due to their history together, or Wendy Corduroy who was his first crush and safest choice, despite both being subconsciously uncomfortable with dating each other due to the previous age difference.

Soos' subplot
After Melody tells him that she is pregnant, Soos struggles to cope with approaching fatherhood, as well as fearing how he will be able to make enough money to support his family due to Stan and Ford's return to the shack. Melody also wants Soos to get a home of his own, which causes him to become anxious about independence and moving forward. Soos is also afraid of becoming his father, thinking he'll screw up as a parent and become a burden.

Wendy's subplot
Wendy realises that it's her time to move out of her family home and she's afraid of taking the first step into adulthood. Since her mother was no longer in the picture, she put herself in charge of looking after her brothers and took too much responsibility for them. Now that she's moving out, she's afraid of abandoning them.

The Trials
For each elder god. the heroes must undergo a trial. Each trial is unique and the number of contestants is chosen by the god.

Corpus's Trail
For Corpus's trial; Wendy must fight one of his champions and she is told that he is a ruthless, brutal fighter who won't stop until he succeeds. Wendy and the champion begin to fight and it's revealed that the two are equally matched. Once the two reach a stalemate, Wendy realises the champion never struck first and is only getting stronger the more she fights. Realising the champion is only fighting in self-defence; she throws her weapon aside, surrenders and apologises.

The champion stops short of beheading her and reaches his hand out as a gesture of forgiveness and as a peace offering. Corpus comes out clapping his hands and tells Wendy she passed the trial.

Anima's Trail

For Anima's trial; Soos, Dipper, and Mabel have to find a rune to escape a bathhouse but they must avoid the rising the water before they drown in it. As the water begins to rise, the trio starts looking but are eventually forced to run up the stairs to avoid the rising water. When they have nowhere else to go, they decide to climb out a nearby window and forfeit the trial, however, Mabel notices a glowing rune beneath the water but realises she can only see it in shadows.

Learning this from Mabel; Soos and Dipper use their clothes to block the sunlight and the trio dives into the water, they reach the rune and pull it out. This flushes the three out and they are reunited with Wendy and Anima, who tells them they have passed the trial.

Vita's Trail

For Vita's trial; Each hero must go through a trial individually and all four of them must pass.

Soos
For Soos, he is confronted with a boulder rolling towards him down a hill, each time he dives out of the way the room will get smaller. After diving out of the way several times, Soos realises he must grab the boulder and roll it back over the hill and roll it through the doorway on the other side. Soos grabs it and starts rolling it up the hill; as he is rolling it, the boulder starts speaking to him and cursing him in his father's voice and expressing pride for abandoning him.

Soos ignores it at first but realises the boulder cannot fit through the door. After enduring more insults, Soos finds the strength to fight back and starts berating his father for abandoning him and swearing to be a better father than him. By doing this, he successfully shrinks it to the size of a coin. The boulder still insults him but it's too small for Soos to hear and he simply walks through the door with the boulder in his pocket. This allows him to pass the trial.

Wendy
For Wendy, she's stood on the edge of a cliff and sees her 3 brothers who are running towards the edge. She instinctually protects them and throws them aside, not realising she's actually injuring herself and them each time. When she looks over the cliff edge, she realises the water may not be as shallow as she thinks. She then convinces her brothers to hold her hands and they all dive into the water together.

They all reemerge unharmed and embrace each other. After her brothers tell her they will be fine and they will always have each other's backs, Wendy swims through the doorway and passes the trial.

Dipper

For Dipper, he's placed in a maze and must find his way out. He instinctually follows Stanford, Wendy, and Pacifica so he can find a way out but realises he's only running in circles and running deeper into the maze. Realising he must go in his direction, he does the opposite of what Stanford, Wendy and Pacifica tell him. By doing this, he eventually finds his own way out but it stuck between Wendy and Pacifica.

Both spirits start using Dipper's feelings against him until he realises a handle shaped object on the wall between the spirits, he grabs the handle and pushes it. This was the exit the entire time and Dipper simply walks through, passing the trial.

Mabel

For Mabel, she's placed in an arena and forced to run from a giant spider. The spider starts attacking her with web and it begins covering the area with cobwebs. This forces Mabel to confront the spider and she eventually realises the spider's weakness, it can't see her if she stands still in front of its side-eyes. Mabel manages to trick the spider into destroying parts of its own web and traps it when it stumbles into a pillar, which causes the pillar to fall on the spider.

Mabel grabs the token from the spider but realises she can't progress without the spider. She returns to the spider and releases it from the rubble. The spider then helps her return to the door and they both walk through it, allowing Mabel to pass the trial.
