Elsa Lychkoff is a murdered Morewood School honor student who was tortured along with her sister Katrina to be an academic success, all for paying for their father Joseph's gambling addiction. Elsa was the more successful of the two sisters, so she made it all the way to the academy with much respect and talent.
After a while, she started to platonically bond with dropout Danny Burke and also wanted out. She was as ready as her roommate Jennifer Banks, who saw Elsa as her biggest obstacle to be in first place at the university's programs. When seeing Elsa in Hoboken with Danny, Jennifer blackmailed her to get her to dropout, but when Elsa insulted her back, Jennifer killed her in a psychotic breakdown, throwing her into the Hudson River, where Elsa drifted to New York City.
She was unidentified until a sex trafficker, Alik, revealed her identity from Ukrainian magazines he read that featured reports of her. Joseph was found out, but he smashed his head and was hospitalized before being acquitted of her murder. When Jennifer confessed in her mania, she was tried as an adult, but her sentenced was reduced to her diminished capacity from the ADHD medication she was on that resulted in her psychosis.
