Kalin summons Infernity Doom Dragon, while Yusei summons Stardust Dragon. Using an equip monster, Yusei manages to defeat Kalin. However, Barbara betrays Yusei, attacking him whilst Kalin is taken away. The Malcolm family's top dog, Lawton, then appears and duels Radley, beating him before he even gets a turn. Barbara and the Malcolm family had used Yusei all along to remove Kalin from the Radley group so they would be easy prey . Yusei, along with Kalin and Radley, are taken to the mines and given shock collars. Yusei finds a means of escaping, but Kalin still refuses to be helped. Meanwhile, Nico and West sneak off with Yusei's Duel Runner.
