Resident Evil: Every Raccoon City Survivor EXPLAINED
6. Sherry Birkin
Daughter to Annette and William Birkin, Sherry might be the most innocent individuals caught up in all of this. Though uniquely tied to the events that took place in Raccoon City she owes her life to Claire Redfield, Claire not only found Sherry, but made sure she received an antidote and escaped.
Once William was consumed by the G-Virus he ran rampant around the cities underbelly, until he finally located his daughter. Because she shared the same DNA she would be perfect to continue hosting the G-Virus and this other than his paternal instincts drew him to her.
After escaping Raccoon City along with Claire and Leon, Sherry was held in protective custody until BSAA and Chris Redfield finally put an end to Wesker. Yes, that time he punched a boulder into a volcano.
She then joined the Division of Security Operations and put her unique understanding of bioterrorism to good use. Thus follows the events of Resident Evil 6.
