One week after Alex 's birth , Benjamin Linus ( Michael Emerson ) came and took Alex from Rousseau . Ben told Rousseau that the child would be safe with them , and that she was lucky for being left alive . Before leaving , Ben tells her that if she hears whispers , she should run the other way . After this , Rousseau began setting traps in the jungle with the hope of catching one of the people responsible for Alex 's kidnapping .
