Several months prior to the destruction of Raccoon City, during the Mansion Incident, Chris found the Arklay Research Lab and uncovered Umbrella’s plot. But due to a systematic cover-up, the entire matter was cloaked in darkness and none of his information saw the light of day. At that point, Chris decided to travel to Europe to look into matters on his own. When Chris departed, he broke off contact with his younger sister, Claire in order to avoid exposing her to danger. But anxious about his safety, Claire set off by her self to find him, and subsequently got caught up in the Raccoon City Disaster. She then followed her bother to Europe, was captured by Umbrella, and imprisoned on Rockfort Island. After learning of Claire’s imprisonment from Leon, Chris took off immediately for Rockfort Island. There he met Albert Wesker, picked up on Claire’s trail, and travelled to Antarctica.
