Rousseau later tells the survivors of Oceanic 815 that two months after their arrival, that the island natives, which she called the Others, carried a disease that the rest of her crew had contracted. She believed that this disease could not be allowed to reach the rest of the world, so she killed her colleagues, including her husband Robert. When Jin time-travels to the past, he witnesses a different version of Rousseau's past. It is shown that the Smoke Monster, not the Others, was responsible for the "sickness" that forced her to kill her crew. Rousseau confronts the father of her child, Robert, at gunpoint and accuses him of "being changed" inside the temple. Robert denies this, explaining that the Monster is a security system for the temple, and convinces Rousseau to lower her weapon. He attempts to shoot her when she does, but is shot by Rousseau. Rousseau also attempts to kill Jin, having witnessed him vanish moments after her team entered the Smoke Monster's lair, believing he has the disease.
