S2E6 The Crimson Avenger

Cubbi insists he's dedicated to Calla's quest for knighthood, which frustrates the Gummis, who suggest he venture into the woods to prove himself. After rescuing some villagers from a highwayman, Cubbi earns the title "the Crimson Avenger." Although he successfully defends them, the highwayman decides to take up residence in Dunwyn Castle, eyeing more lucrative opportunities. This decision soon leads to complications for Calla, Cavin, and King Gregor, as they face the fallout from the thief's new ambitions.
