Episode C is the ninth episode of the fifth and final season, and also the sixty-first and penultimate episode of the Samurai Jack show. It aired on May 13th, 2017. While the fifth season episodes are untitled, this episode can be unofficially titled Jack and Ashi Find Aku or The Triumph of Aku
Samurai Jack's worst fear is realized when he faces off against Aku; the demon makes a shocking discovery about Ashi that puts her in grave danger.
The episode picks up immediately where XCIX left off. Ashi and Jack quickly realize they are kissing and stop, nervous and mildly disgusted from Lazarus 92's venom. Ashi offers Jack his gi, but he insists that she keep it until she finds new clothes, claiming the ship is drafty. Soon, they spot a hole in the ceiling leading outside. Ashi searches for something to wear while Jack heads back outside, finding a broken water pipe. After Ashi finds a large sweater and boots in a locker room, she comes across Jack showering outside and kindly leaves him his gi. In private, however, Jack sees a bearded reflection of himself, warning him to be careful. Jack himself agrees, since this has never happened to him before and wonders what to do. That evening, after hunting some worms for dinner, the two awkwardly try to make small talk. Ashi asks Jack if he ever thinks about his home, and Jack answers that he does so all the time, opening up to her with the memories of his home throughout the seasons. When Ashi asks if there was a girl in his life, Jack explains there wasn't time, since he was only 8 when Aku returned. While Jack admits the time before Aku was nice, the memories of his home are the only way he will see it again. The next morning, a distraught Ashi wakes up to find that Jack has left her again.
Meanwhile, an overjoyed Scaramouche finally arrives at Aku's lair on top of an octopus. He spots Aku in the distance, only to find it's actually a speaker-box in the demon's likeness that refuses to hear him out and ordering him to leave. Still persistent, Scaramouche simply finds another way into Aku's lair and demands to speak with him. When Aku reluctantly agrees, Scaramouche wonders if Aku can hear through his antlers before finally confirming the status of Jack's sword. Rejoicing at the revelation, Aku restores Scaramouche's body and dances along with him in celebration.
Back in the desert, Jack returns to a familiar robot graveyard, eventually discovering that the Guardian and his time portal have both been destroyed. Ashi soon confronts him, demanding to know why Jack left. Jack explains that, in addition to witnessing the suffering of many innocent people, Aku has taken everything from him, leaving him with nothing but memories, and doesn't want the same to happen to Ashi. Instead, Ashi assures him they were brought together for a reason and will defeat Aku together.
Mere seconds later, Aku reveals himself, followed by Scaramouche. Aku claims he is aware that Jack lost his sword, having learned of this information from Scaramouche. When Jack reveals the opposite, Aku telekinetically destroys Scaramouche's head in frustration. He casually prepares to leave as Jack attacks him, but smells something familiar nearby: himself. Much to Jack's confusion, Aku calls a timeout before approaching Ashi, who grabs a nearby sword to defend herself. After another sniff, Aku announces that he smells a piece of himself inside Ashi, much to her shock. Wondering how this could've happened, Aku remembers the time when he personally paid a visit to the members of the Cult of Aku. Impressed by their worship of him, Aku gave them some of his essence, which leads to the deduction that Ashi's mother must have (somehow) consumed some of Aku's essence, which ultimately led to the conception, pregnancy and birth of Ashi and her sisters--this means that Ashi and her sisters are in fact the literal (as in "biological") Daughters of Aku.
Horrified, Jack attacks Aku once again, only for his blade to be blocked...by Ashi, who seems just as stunned as him. Using his essence inside Ashi, Aku's able to control her body like a puppet, forcing her to fight against Jack. Jack pleads with her to resist, but she is unable to do so. Unhappy with the way the battle is playing out, Aku tells Ashi she needs to "bring out her best" (i.e., himself) and pours more of his power into her body, causing the dormant essence to transform her into a demonic version of herself.
Initially outclassed by the transformed Ashi's new abilities, Jack manages to break Ashi's sword and cut her arm, briefly getting through to her. Ashi begs Jack to kill her and stop Aku, but he can't bring himself to do so and stands down. Before Ashi can finish Jack, Aku orders his daughter to stop, joyfully claiming the Samurai's sword as Jack admits defeat.
