The Heir Apparent
The Archbishop of Povia must designate a heir to succeed the departed king as regent, as the king left no heir. General Qaisette plans to seize the throne in a coup if he isn't named. The IMF spread rumors that Princess Celine, who disappeared as a child, is returning. Cinnamon studies Celine's life. Barney and Willey lead Qaisette to Phelps who has an elderly blind Celine/Cinnamon. Thanks to Rollin who claims to be a doctor who knows about the ""real"" Celine's crippled arm, Qaisette believes he can use the ""fake"" Celine to discredit the Archbishop. But Cinnamon manages to pass every test (with some help from Barney) and Rollin ingeniously sneaks out before Qaisette can call him as a witness. Cinnamon-as-Celine has Qaisette arrested and then abdicates the throne, disappearing once more.
