pursued by Nemesis, a supersoldier whose task is to kill all remaining members of the STARS team. Instead of killing Valentine, Nemesis infects her with the T-virus; her new partner Carlos Oliveira – a former Umbrella mercenary – cures her of the infection with an Umbrella-produced vaccine. The Umbrella Chronicles occurs in 2003, when Valentine and Redfield join a private organization with the goal of exposing Umbrella's biological warfare activities, leading a group to destroy their only remaining research facility. After the fall of the corporation, the pair become founding members of the United Nations' Bioterrorism Security Assessment Alliance (BSAA). In Revelations – set two years later – Valentine and new partner Parker Luciani are sent on a mission to rescue Redfield, who is allegedly being held hostage on a ghost ship in the Mediterranean. Once aboard, she discovers the ship is infested with a new type of mutagen capable of infecting the aquatic ecosystem. Valentine and Redfield then unravel a political conspiracy involving an earlier mutagenic outbreak and a botched investigation by a rival agency. Resident Evil 5 takes place in 2009 in the fictional African town of Kijuju, where terrorists are turning local residents into zombies. One of these terrorists is revealed to be Valentine, who was missing in action for the previous two and a half years. Set in 2006, the Lost in Nightmares DLC showed Valentine and Redfield searching inside a mansion for Umbrella's founder; to save Redfield from Wesker, Valentine tackled the latter through a window. Neither of their bodies were recovered, and Valentine is declared dead. In fact, she was injured by the fall and taken hostage by Wesker, who then used her as a test subject in his biological experiments. The antibodies produced by Valentine's system as a result of her Nemesis-era T-virus infection were used as the basis for the Uroboros Virus, the catalyst for the events of Resident Evil 5. During Resident Evil 5, Redfield discovers that Valentine is alive; Wesker attached a mind-control device on Valentine which forced her to commit the terrorist acts and fight Redfield and his new partner, local BSAA agent Sheva Alomar. Valentine finds enough self-control to open her outfit so the device can be seen and removed. After its removal, she explains that she knew what she was doing but was unable to control her actions and urges Redfield and Alomar to continue their mission.
