- "Not your hair, stupid!"
- ―Dr. Suchong[src]
Thanks to the Lutece Device, the Columbian scientist Jeremiah Fink and the Rapture geneticist Dr. Yi Suchong managed to collaborate with each other, sharing info from a different universe and time period. They both wanted to get their protectors to imprint on their subjects (The Big Daddy and the Little Sister, the Songbird and Elizabeth) and while Fink succeeded, Suchong did not. After his breakthrough, Fink felt that there was no point in continuing the arrangement with Suchong and broke off their contact. Suchong desperate for finding a way for his pair of subjects to imprint, believed the answer would be found in the DNA of a Hair Sample from Fink's subject.
Burial at Sea - Episode 2Edit
Elizabeth's plan was only to briefly enter Columbia again in an attempt to get a Lutece Particle for Atlas. But as she tries to enter the Tear back to Rapture, Suchong refuses to open the Tear and let her pass through. As there is no way for Suchong to obtain the hair sample himself, he blackmails Elizabeth into finding the sample for him. In exchange he would allow her get back to the department store. With only minor help from Suchong for the whereabouts of the sample, she heads for the abandoned Fink MFG Research Laboratories at the Factory. It is seemingly impossible to find in the vast area, but after some searching she gains access to the Imprinting Studies. Here Elizabeth sees a projection of herself imprinting on the Songbird, revealing that the actual formula is empathy. Soon after this, she finds the sample among other of her personal effects, and the sample turns out to be her own. She heads back to Rapture, where she places the sample into a Pneumo Tube, delivering it to Suchong, unaware of the consequence.
Later on, Elizabeth finds the hair sample in Dr. Suchong's Free Clinic, along with Suchongs failed tests for the imprinting formula.
