The ending of Triangle fits together as a repeating voyage Jess cannot break. She leaves the liner, relives the same morning at home, loses her son, then boards the yacht again. Triangle is the capsized yacht that starts the story, and Aeolus is the empty ocean liner Jess boards afterward. Each return adds bodies and objects instead of wiping the ship clean, so later versions of Jess meet earlier ones.

How does Jess enter the loop?
Jess joins friends on Greg's yacht Triangle, which capsizes in a storm. She then boards the apparently abandoned ocean liner Aeolus, already feeling she has visited it, according to the British Council's film synopsis.
That sense of familiarity matters. Jess is not exploring a new place; she is reentering a cycle. Her confusion gives way to recognition as events repeat.
Who is the masked killer?
The masked shooter hunting the group is a future version of Jess herself. Multiple versions coexist aboard, fight one another, and try to change what happens next, according to SlashFilm's ending breakdown.
This is why victims and attackers sometimes share injuries, clothes, or knowledge. One Jess tries to save her friends, another tries to kill them to force the pattern forward. Neither effort stops the voyage.
What proves the cycle leaves marks?
Each loop leaves physical residue rather than fully resetting. Those traces include Jess's keys and son's-photo locket, handwritten notes, corpses, and accumulating dead seabirds, according to High On Films' analysis. Viewers can therefore track progress through objects.
A fresh note becomes an old warning. A dropped key becomes the key found later. The gulls work the same way on land.
Why does Jess return to the yacht?
After being knocked overboard, Jess washes ashore that same morning, goes home, kills the abusive double of herself, and flees with her son Tommy. While driving, she hits a seagull, finds a pile of identical dead gulls, then crashes into a truck that kills Tommy and her other self, according to the film plot summary on Wikipedia. Survivor Jess then accepts a taxi driver's ride to the harbor after promising she will return.
She rejoins the yacht party and restarts the voyage. Writer-director Christopher Smith ties the structure to Sisyphus, naming the ship Aeolus for Sisyphus's father and calling the theme regret over an unchangeable act. Practically, viewers should track Jess by clothing, mask, and wounds to fit cycles together.
