Mother Knows Best / The Grandfather Clock, Poppo Time.Yusei's landlord, Zora, is depressed because the city wants to replace the broken cuckoo clock on her clock repair shop. Later, the gang are visited by Zora's son, Lynden, who has returned after three years of training to fix the clock. When he goes to see Zora again, she is not happy to see him, since he was the one who broke the clock in the first place. Before he can run off, Crow challenges him to a duel, forcing him to apologize if he won. Crow runs into a bit of trouble with Lynden absorbing one of his monsters and summoning out his Clock Knight monsters that rely on coin tosses, but soon comes back with his Blackwing Armor Master. Lynden tries to back off from the duel, but Crow tells him he needs to stop running away from his problems. Lynden summons a Time Wizard he got from his late father to destroy Crow's monster. Crow decides to take the damage instead of activating his Mirror Force, since Lynden had realized he can't keep running away regardless of his victory. Lynden successfully fixes the cuckoo clock and rekindles his relationship with Zora.
