Metal Gear Solid: The Shadow Moses Incident

Enclosure

Just then, Snake was discovered by Ocelot. Snake lost track of the PAL key after Ocelot shot it out of his hand. Snake was able to find the PAL key in the drainage ditch before being poisoned from the radiation.[4] After having been taken into custody by Campbell, Naomi called Snake and told him that she was, in fact, a spy. She then went on to tell Snake why she did what she did, revealing that her brother was Frank Jaeger (better known as Gray Fox), which shocked Snake. He had adopted her in Rhodesia after her parents were killed. She had simply bought her identity of Naomi Hunter, and didn't even know her real name. It was after the Rhodesian Civil War that Big Boss had brought Frank and Naomi over to America, just before Big Boss and Frank went off again, to fight in the Mercenary War where Frank was nearly killed by Snake. Filled with pure hatred for Snake, Naomi joined FOXHOUND and waited for her time. She revealed to Snake that he had been injected with FOXDIE, an artificial virus that targeted specific people and caused the victim to suffer a heart attack. He had been injected with it so it could be used to kill off FOXHOUND and Baker, but Naomi had re-engineered the virus so that it would kill him too. However, she admitted that she no longer hated him, after learning his point of view on the fight with Gray Fox. She also told him that while she did hate him for crippling her brother (and thus indirectly putting him in gene therapy as a guinea pig), her hatred wasn't the primary reason why she injected him. Just before she could reveal the truth, Campbell wrestled her down and told Snake that he was forbidden to talk to her, but Snake was deeply upset at Campbell due to him being "betrayed and used."

Eventually, Snake inputted all the three PAL keys, only to discover that he had inadvertently activated Metal Gear REX himself. Confused by how this could have happened, Snake was soon contacted by Miller. He revealed to Snake that Anderson's and Baker's detonation codes had never been used as the terrorists had been unable to obtain the former's before his death. He also revealed that Octopus had posed as Anderson to trick Snake into locating the PAL keys, but FOXHOUND hadn't anticipated that Snake would be a carrier for FOXDIE. Just then, Campbell called Snake and told him that the person he was talking to wasn't Miller. He told him that the real Miller had been dead for three days which shocked Snake. In addition, although Campbell initially didn't know about Miller's death due to Miller's Codec being cut off from Campbell, Mei Ling had traced "Miller's" frequency from being within Shadow Moses. After the truth came out, Miller revealed that he was actually Liquid in disguise. Liquid trapped Snake in the control room and activated the soman gas valves, but Snake was able to easily escape after calling Otacon for help. After escaping, Snake finally confronted Liquid, face-to-face, and Liquid explained that he disguised himself as Miller in order to trick Snake more easily, and also revealed how the people who were using him as a disease vector were the people who recruited him: the Pentagon. Naomi was working with the Pentagon on making the virus program, although they did not anticipate that she would modify FOXDIE to target Snake out of revenge. He also explained that the reason the Pentagon decided to inject Snake with FOXDIE was so they could recover the Genome Soldier bodies as well as the Metal Gear REX weapon undamaged.

After explaining this to Snake, as well as briefly stating that he and Snake were not ordinary twins, but twins that were clones of Big Boss as a result of the Les Enfants Terribles project, as well as expressing his hatred for both Snake for receiving the dominant genes (making Snake "the dominant one"), and their father, Big Boss for apparently choosing Liquid knowingly to be the inferior one. Liquid told Snake that he wanted to kill Big Boss and exact revenge, berating his brother for "stealing that chance", as well as saying that by following Big Boss's legacy, he would "surpass and destroy [Big Boss]."
