Lost: Maternity Leave

When Claire’s baby, Aaron, comes down with a mysterious illness, Rousseau shows up hinting that her missing two weeks may hold the key for a cure. She enlists Libby to hypnotize her to try and retrieve her memories and slowly they come back to her, remembering how Ethan kept her drugged and injected the baby with an unknown elixir. Claire, Kate and Rousseau set out to find the vaccine using Claire's returning memories as a guide. They discover the now-empty bunker where she was held, along with the costume, the bearded other donned when confronting the castaways but no vaccine. Claire recalls a teenage girl who saved her and how Rousseau tried to help her when being hunted by the Other's and strongly suspects the girl may be Rousseau's long-lost daughter.
