S01E60: Truth and Consequences (1)

Akiza and Mina arrive at an abandoned amusement park where Ccarayhua's control unit is, shortly followed by Yusei's group, and a man claiming to be sent by Goodwin. Misty traps Akiza in a Hall of Mirrors, actually dueling her through the mirrors. She uses cards that block off drawing cards from the deck, and also shows Akiza the events involving Misty and her brother, Toby, who apparently met her at Arcadia Movement. Yusei is led to a room where Mina is found unconscious and is attacked by the man who turns out to be Sayer, who had survived his duel with Carly, and is determined to reclaim Akiza. He uses his psychic abilities to knock Yusei in a cage with Mina as it slowly fills with water. Trudge eventually finds them and tries to free them. Akiza is shown the moment where Toby was killed, which led Misty to become depressed and crash her car, transforming her into a Dark Signer.
