chunk: After a poignant attempt at radio communication with an Eskimo–Aleut-speaking fisherman on Earth, Stone resigns herself to being stranded and shuts down the cabin's oxygen supply to commit suicide. As she begins to lose consciousness, Kowalski enters the capsule. Scolding her for giving up, he tells her to rig the Soyuz's soft landing jets to propel the capsule toward Tiangong. Stone then realizes that Kowalski's reappearance was not real, but has nonetheless given her the strength of will to continue. She restores the flow of oxygen and uses the landing jets to navigate toward Tiangong on momentum.
