Yugi finally overcomes Yami Bakura's tactics when he summons Slifer the Sky Dragon, but Marik plots to make him face a difficult decision when he persuades Yami Bakura to release control of a badly injured Bakura: would Yami Yugi rather save the world or risk harming a friend? However, Yami Bakura decides not to take the risk, since he needs Bakura in good health, because Bakura is the holder of the Millennium Ring and the host for Yami Bakura's spirit. As a result, Yami Bakura regains control, much to Marik's shock, which allows Yami Yugi to follow through with his attack and win the duel, once again leaving the good Bakura in a coma. While taking care of Bakura, Yugi and Joey realize his Millennium Ring is missing.
