Who is ames in Metal Gear Solid 2

Colonel Richard Ames is a secret agent and an operative for the Patriots who is taken hostage during the Big Shell incident. He previously served the Defense Intelligence Agency, where he met Natasha Romanenko. He was married to Nastasha for a while, but the two ended up in divorce. He worked with his ex-wife in California from behind-the-scenes during the Shadow Moses incident. He was the one who ordered Naomi Hunter to inject Solid Snake with FOXDIE and he was also Naomi's lover for a short time. At the end of the mission, he places Housemans under arrest (after Houseman ordered an air strike over the disposal facility) and provides Nastasha with a disk containing data about FOXDIE. Years later, during the Big Shell incident, he is placed as a spy by the Patriots when the facility is taken over by Sons of liberty. He was sent to monitor President Johnson's allegiance with the terrorists, but is taken captive among other hostages in the Shell 1 Core. Ames meets Raiden (in disguise as a Gurlukovich soldier) and provides him with information about the terrorist activity and the President's role. However, he is unaware of his "role" in the S3 Plan and Ocelot's affiliation with the Patriots. Because he betrayed the Patriots by giving Nastasha the disk containing data about FOXDIE and letting her escape, he is killed. The Patriots had infected his pacemaker with controllable nanomachines. The appearance of his sudden death is remniscient of Decoy octopus's death by FOXDIE, directly referencing another part of the S3 Plan.
