Complete story — includes the ending
Michael is taken to Windmark, who is unable to read his mind. While Michael is being examined, Broyles relays to the team that Michael is on Liberty Island, which is heavily fortified. On Olivia's suggestion, she is injected with Cortexiphan, allowing her to cross over to the parallel universe. She finds it unspoiled by an Observer invasion, and reunites with Lincoln Lee ( Seth Gabel ) and Fauxlivia, who run Fringe Division and are married. Olivia makes it to Liberty Island, crosses back over to rescue Michael, and returns to the parallel universe, where Lincoln and Fauxlivia stop a pursuing Observer. After leaving the island Olivia and Michael return to their universe. September builds a device that would enable Michael to travel forward to 2167, but turns to former colleague December for assistance when the initial attempt fails. Windmark learns that Broyles is relaying information to the team.
