Rin was part of the survey team that landed on Aegis VII to look for the fragments of the Marker and during the debriefing in Kuttner's flashback, it was her who mentioned Isaac Clarke. She was the first to find Nickolas Kuttner after he found a shard of the Marker. She attempted to calm Kuttner down before his psychotic breakdown which led to the death of Noah Pawling.
She died shortly after saving Nolan Stross from falling into the lava which she fell into when the ground that she stood on broke apart. Because Rin saved Nolan Stross, she inadvertently contributed to the destruction of the O'Bannon, the massacre of its crew and the death of Nolan's family when the Red Marker fragment caused Nolan to hallucinate and see his family as Necromorphs. Rin's sacrifice to save Nolan was ultimately in vain as in Dead Space 2, Isaac Clarke was forced to kill Stross in self defense.
