She recovers the Lutece Particle easily enough, but before she can return to Rapture, Suchong closes the Tear and forces her to collect a lock of hair from one of Fink's hidden laboratories. She finds herself aboard The First Lady during the time when Booker and Elizabeth had stormed Jeremiah Fink's factory with the Vox Populi. Elizabeth then travels through a Tear back to Columbia. She collects equipment needed to repair the vandalized device with the reluctant help of Atlas and Suchong. Elizabeth rationalizes that she can use the Lutece Particle that kept Columbia afloat to lift the department store back to Rapture. Tracking down Suchong, Elizabeth discovers the doctor knew about Columbia and built a Lutece Device connecting back to the flying city, based on the Luteces' technology. The voice of Booker, who states he is simply a facet of Elizabeth's subconscious, helps her in making her way through the Splicer-inhabited store. The Lutece Twins had advised her not to venture back into Rapture, because her quantum-superposition would collapse into one last Elizabeth, mortal, without omniscience or the ability to open Tears, and cut off from the Elizabeths of the alternative universes, but she was determined to return to Rapture and rescue Sally. However, her powers allowed her to continue existing in some form in the multiverse, and her sense of guilt about the way she used Sally to get revenge on Comstock, moved her to get back to Rapture and clean up the mess. She realizes that her former self was killed by the same Bouncer that impaled Comstock. Left alone, Elizabeth begins to explore the store and finds her own dead body amongst some rubble. Yi Suchong to convince him and promises freedom in exchange for returning Sally. Before they can shoot Elizabeth, a vision of Booker DeWitt appears and coaches her to claim she can help Atlas escape the sunken department store. Atlas and his men take Sally away and search the corpse of Comstock for valuables. Elizabeth wakes up in the Toys section of Fontaine's Housewares Department shortly after the events of Episode 1.
