Jack Tannager

Jack Tannager was a survivor of the 2002 global T-virus outbreak, having been a young boy at the time. Living with his uncle Chunq on Catalina Island, they were largely isolated from the remainer of civilization, bar the occasional dealings with waterbound refugees.

After Umbrella Prime was fallen, Jack helped scuttle an Umbrella submarine found to be housing Las Plagas Undead. With that taken care of, he developed an attraction towards Dori, a clone engineered by Umbrella for viral research.

Further notes
As the official noveliation of Resident Evil: Retribution, it is presumed the new additions to the storyline are part of the W.S. Anderson movie canon.
