Mouthwashing Plot Explained: Timeline and Ending Guide

What Happens in Mouthwashing?

The Mouthwashing plot begins with a wreck, but the disaster started long before the Tulpar hit anything. Its fractured timeline gradually exposes co-pilot Jimmy as the man responsible for the crash, while Captain Curly takes the blame. Put those scenes in order, and the story becomes a brutal account of abuse, failed leadership, and the refusal to take responsibility.

Full spoilers follow, including discussion of sexual assault, suicide, and body horror.

Five people are trapped aboard the damaged space freighter:

• Curly: The captain, whose catastrophic injuries leave him conscious but unable to speak or care for himself.
• Jimmy: The co-pilot, who assumes command after the crash.
• Anya: The ship's medic, responsible for caring for Curly while facing abuse herself.
• Swansea: The experienced mechanic, who guards the utility room.
• Daisuke: Swansea's inexperienced intern, eager to prove himself.

The ship has roughly six months of power remaining, with food expected to run out much sooner. Their cargo offers no meaningful escape from starvation: the hold contains mouthwash.

The central mystery concerns how they reached this point. Before the crash, you play as Curly. Afterward, you mostly experience the ship through Jimmy, whose accusations and hallucinations distort your understanding of the crew.

Before the Crash: Anya's Pregnancy and the Layoffs

Before the collision, the Tulpar already has serious problems beneath its ordinary workplace routines.

Jimmy sexually assaults Anya, leaving her pregnant. She tells Curly that she is pregnant. Curly helped Jimmy get his position as co-pilot.

That failure matters more than whether Curly seems friendly or well liked. He holds authority aboard the ship, yet Anya remains trapped alongside the person who harmed her.

Anya's professional background also complicates Jimmy's dismissive view of her. She has tried to enter medical school eight times and qualified for her shipboard position through Pony Express nursing classes. Her credentials are limited to the company's jurisdiction, but she continues studying and working toward a future beyond the freighter.

Meanwhile, Pony Express is shutting down. Curly breaks the news during his birthday celebration: everyone will lose their jobs after the delivery.

Curly is losing his job too. He is set to receive a commendation and exceptional references, which give him better prospects than his coworkers. Jimmy resents that advantage and treats Curly's future as evidence that the captain will escape consequences while everyone else suffers.

For Jimmy, the impending layoffs and Anya's pregnancy threaten his ability to avoid accountability.

Who Crashed the Tulpar?

Jimmy deliberately crashes the ship. He disables the autopilot and steers the Tulpar into an asteroid's path.

The opening conceals the identity of the person at the controls. Later scenes expose Jimmy's responsibility and overturn the accusation against Curly.

Curly attempts to intervene as the collision approaches. He suffers devastating injuries, losing his limbs and ability to speak, while the crew survives the immediate impact.

Afterward, Jimmy assumes the captain's role and blames Curly for their situation. Curly cannot answer the accusation or explain what happened.

This creates the story's cruelest imbalance: the person who caused the wreck controls its explanation, while the person blamed for it depends on him for basic care. Jimmy berates Anya for being unable to feed Curly his painkillers.

Curly's earlier failures remain part of the story, but they are distinct from Jimmy's deliberate actions. Failing to protect Anya and intentionally crashing the freighter carry different responsibilities.

After the Crash: Why the Cargo Contains Mouthwash

Emergency insulation foam seals damaged sections of the Tulpar, leaving parts of the ship inaccessible. As supplies dwindle, the crew eventually opens the cargo hold in search of something useful.

They find an enormous shipment of identical mouthwash bottles.

The discovery turns a possible lifeline into an absurd disappointment. The crew has been transporting a commercial product that cannot solve their basic survival needs.

Swansea begins drinking the mouthwash, ending 15 years of sobriety. His relapse develops alongside his increasingly hostile behavior and his determination to keep the utility room locked.

The mouthwash also becomes part of Jimmy's destructive attempts to improvise solutions. When Daisuke is later injured, Jimmy uses it on his wounds as an antiseptic, making the situation worse.

How Anya, Daisuke, and Swansea Die

The final breakdown begins when Anya locks herself inside the medical room. Jimmy recruits Daisuke to help him get through the utility room, despite Swansea's refusal to grant access.

Jimmy and Daisuke incapacitate Swansea with a spiked drink and take his key. Inside, they discover that one cryogenic pod still works.

Jimmy immediately interprets Swansea's secrecy as selfishness. Swansea's attachment to Daisuke gives that secrecy a different meaning: he has been preserving the remaining chance of survival for his intern.

Anya's Death

Anya dies by suicide through an overdose in the medical room.

Her death follows prolonged abuse, isolation, and the collapse of any believable route to safety. She has continued caring for Curly and helping the crew while Jimmy belittles her.

Pay attention to the gap between Jimmy's complaints and Anya's actions. Tasks he treats as proof of her incompetence often involve her directing him toward necessary care. His narration encourages you to dismiss the person doing much of the work.

Daisuke's Death

Jimmy persuades Daisuke to crawl through a damaged vent into medical, appealing to his desire to make Swansea proud.

Daisuke suffers severe injuries but manages to open the room. Jimmy's attempt to treat him with mouthwash fails. Swansea ultimately kills the suffering Daisuke with the emergency axe.

Their relationship makes this especially painful. Swansea often sounds impatient and contemptuous, while Daisuke keeps trying to earn his approval. Beneath that friction, Swansea wants him to have a future.

Daisuke did not initially want the internship; his parents pushed him toward it because they worried about his direction in life. His eventual determination to do well makes Jimmy's manipulation particularly cruel.

Swansea's Death

Jimmy kills Swansea with the ship's gun.

The surrounding sequences blur pursuit, confrontation, and hallucination. One scene presents Swansea restrained in a chair, confronting Jimmy's cowardice before Jimmy shoots him.

Separate that clear outcome from the unstable imagery around it. Swansea dies at Jimmy's hands, regardless of how Jimmy's perspective rearranges their final conflict.

The Ending Explained: Does Jimmy Save Curly?

After the others die, Jimmy stages a grotesque version of Curly's birthday celebration. He gathers the bodies around the table, places Curly at its center, and imagines approval from the crew.

He amputates part of Curly's leg and eats it. The sequence also implies that he forces Curly to consume his own flesh.

This scene exposes how thoroughly Jimmy's need for validation has overtaken his concern for other people. Even his fantasy of bringing everyone together requires further violence against someone who cannot resist him.

Jimmy eventually places Curly in the last functioning cryogenic pod, which can sustain him for 20 years, then shoots himself.

Curly is alive when Jimmy puts him into cryostasis. The ending does not show a rescue.

Jimmy treats this final act as a way to repair what he has done. Read it alongside his earlier behavior: he chooses a dramatic gesture toward Curly while still failing to meaningfully acknowledge Anya's suffering.

Putting Curly in the pod preserves a possibility of survival. It does not undo the crash, the abuse, or the deaths. The ending leaves Jimmy's preferred image of himself—someone who finally fixes everything—under intense scrutiny.

How the Nonlinear Timeline Changes the Story

The jumps through time control when you can understand each character's behavior.

Early on, Curly appears to be the captain who doomed everyone. Jimmy appears to be managing the aftermath. Once the pre-crash scenes reveal the assault, the pregnancy, and the deliberate collision, those roles become impossible to accept at face value.

The hallucinations push that distortion further. Jimmy encounters accusations, grotesque imagery, and imagined reassurance, but his distress does not automatically produce an honest understanding of his victims.

When revisiting the story, track three things:

• Who is playable: Curly's pre-crash scenes and Jimmy's post-crash scenes provide different access to events.
• Who knows what: Anya's disclosures and Curly's responses change the meaning of later conversations.
• Who benefits from an explanation: Jimmy's claims repeatedly protect his authority or redirect blame.

Watch Anya's practical decisions, Swansea's protection of the utility room, and Daisuke's desire for approval. Their actions reveal motives that Jimmy's account repeatedly obscures.
