Tras el incidente en Raccoon City, el gobierno de los Estados Unidos decidió hacerse cargo de Sherry Birkin y mantenerla en observación debido a que en su sangre quedaron trazas del virus G.
Durante el tiempo en que Sherry sufrió pruebas y experimentos a diario, Claire Redfield permaneció a su lado y le proporcionó apoyo moral. A pesar de ello, Derek Simmons fue quien se convirtió en su tutor legal. Claire visitaba a Sherry siempre que le era posible para ayudarla a superar su trauma y fue entonces cuando la niña empezó a idolatrar a su joven salvadora y decidió que sería como ella de mayor: una mujer fuerte y capaz.
Drex tuvo compasión por la huérfana y permitió que Claire, una civil, visitara y reconfortara a Sherry, cuya mera existencia era casi un secreto de estado. En total, Sherry pasó 11 años en manos del gobierno y no consiguió un poco de libertad hasta el 2009.
Following the Raccoon City Incident, the U.S. government decided to take Sherry Birkin into custody and keep her under observation because of the trace amount of the G-Virus that remained in her blood. Claire Redfield stayed by Sherry's side during the time she had to suffer through daily tests and experiments.
While it was Claire who provided emotional support, it was Derek Simmons who became her legal guardian.
Claire visited Sherry as often as she could, trying to help Sherry overcome all the trauma she had endured. Sherry idolized Claire, and was determined to be just like her: a strong, capable woman. Derek was not without compassion for the orphaned girl, and he allowed Claire, a civilian, to visit and comfort Sherry, even though the girl's existence was a closely guarded state secret.
In total, Sherry spent 11 years in the hands of the government. It wasn't until 2009 that she was given any freedom.
Below is a letter that Claire tried to send to Sherry during this time. The letter was intercepted, but never shown to Simmons. The person who found it sympathized with Sherry and Claire's situation, but couldn't allow it to go to Sherry, so he had it destroyed in secret.
I don't want to make things any harder for you, but I need you to be careful around Simmons. I know he's been supportive and let's me see you, but something's not right with him. I don't have any proof, but I know what people look like when they're hiding something, and I get that feeling every time I look into his eyes. You are so trusting of people, and it worries me. Please just be careful, for my sake.
I'll be busy, so I won't be able to come and see you for a little while. Keep being your cheerful self.
