Johnny, at this point, asks Yami Yugi for his name. When he finds out that his opponent is the duelist who defeated Maximillion Pegasus at Duelist Kingdom, Johnny quits.

Aftermath
Tea berates Johnny for being a coward, and feeling dejected, before leaving, Johnny thanks Tea for being honest with him. After which, Yugi and Tea head to the Domino Museum, looking for the answers to Yami's past.
