Irina is a figure from Alex's elusive past. She is Russian, and most notably hid in the same containers as Alex when they both came to America.
She and Alex meet once again years after Alex's escape in the episode "Alexandra". Irina, suffering from Stockholm Syndrome, helps the recapture of Alex by their enslavers. After Alex is tortured, Irina feels guilty for assisting in her recapture, and apologises, saying she just missed her so much and wanted her back. Irina gives her water and later frees her from the cage she was kept in, enabling Alex to kill Vladimir Ivanov, a man who enslaved her. Alex then lets Irina escape, threatening to kill her if she ever revealed the truth about Alex.
