Greta was one of "The Others", and an occupant of the DHARMA Initiative's Looking Glass Station. When Charlie swam up through the submarine port, ecstatic that he had not drowned, Greta and her fellow occupant Bonnie entered the room with a handgun pointed directly at Charlie in a hostile manner. After Charlie swims into the station, Greta attempts to halt Bonnie's abusive behavior towards Charlie. On Ben's orders, Mikhail shoots Bonnie and Greta, and their bodies are covered as a sign of respect by Charlie and Desmond.
