Complete story — includes the ending
Realising she has been exposed, Fauxlivia drugs Peter and escapes. The next morning, the team find the typewriter (a " quantum entanglement " device) used to contact the parallel universe in a typewriter store. Peter discovers the location where Fauxlivia is going to return to her universe. The team arrive at the station and Fauxlivia is arrested. Meanwhile in the parallel universe, doctors prepare to kill Olivia and use her to help Fauxlivia return. Broyles manages to break her out. The two go to Walternate's old lab in Harvard. She immerses herself in the isolation chamber in time before Broyles is arrested. Olivia successfully crosses over back to the Prime universe, while Fauxlivia returns to hers, leaving behind the mutilated body of "Alternate-Broyles" to make up for her mass. While Peter and Olivia reunite at a hospital, the typewriter store owner trades a man a piece of the doomsday device in exchange for the restoration of his paralyzed legs.
