In 2008, Olga gave birth to Sunny at a hospital run by the Patriots, who took the child away from her, and sent her a photograph of the child monthly. They later used this as a way of forcing Olga to assist Raiden during the Big Shell Incident: if Raiden were to have died during the incident, then Sunny would have been killed by the Patriots. Olga eventually gave her life to protect Raiden, and the child whom she never got to raise. The identity of her father is unknown, but was probably one of the Gurlukovich mercenaries.
