she was the surrogate mother to Snake and Liquid through the cloning process. They move Big Boss' body by boat while Liquid's PMC soldiers attack decoys. Liquid captures the body and obtains the biometrics, intending to infiltrate the Patriots' system by using the repaired artificial intelligence (AI) core, GW, as a trojan. U.S. soldiers arrive to arrest Liquid, but he kills them after disabling their firearms. Big Boss' body is set alight, and Snake saves EVA from the fire when she tries to save the body, but in the process he gets badly injured and his left cheek is permanently burned.
