BONUS
Yudhishthira (Saber) - but as a Lily version of himself so that he can be the pampered little brother for once and not have to put up with his younger brothers’ BS. Duryodhana tries to make fun of him for it and Yudhi goes running to Karna, crying. While Karna chastises Dury for making fun of him, Yudhi evilly smirks at Dury from behind Karna, who faithfully plays into the Big Brother role. EVERYBODY is aware that Yudhi is basically playing Karna besides Karna!
