Episode 8 of Renegade Nell begins with Nell and Billy eagerly awaiting the queen's carriage, hidden among the bushes alongside Roxy, George, and Rasselas. As the carriage gracefully approaches, Nell and Rasselas spring into action, holding it steady. But to their surprise, the woman inside is none other than Devereaux, who has escaped thanks to Eularia's clever plan.
Nell sighs in disappointment and suggests they make their way to Broadwater, Poynton's lavish estate. Upon arriving, the scene turns chaotic as the queen enters and is suddenly betrayed by her own guards. Poynton reveals his treachery and orders her arrest, a shocking turn of events.
Outside, Sofia approaches Thomas with concerns about his earlier doubts regarding Poynton. Thomas appears transformed, and Sofia notices he's wearing Poynton's necklace. She attempts to remove it, but the action causes Thomas immense pain. Meanwhile, Roxy senses an eerie evilness lurking within the estate walls. She and Rasselas decide to trust her instincts and venture inside, leaving George to guard Devereaux.
Inside the estate, Sofia confronts Poynton about the pendant he gave Thomas. Poynton reveals that patricide warps the soul and explains that the energy contained within Thomas can be harnessed by those with dark powers, like them. He further suggests that Sofia, with her strength, could potentially defeat everyone.
However, Sofia isn't fooled by his manipulative words and lashes out, striking Poynton on the head. Seizing the opportunity, Poynton absorbs the energy from Thomas, gaining strength and trapping Sofia in his clutches. Suddenly, a guard rushes in, reporting that other guards have mysteriously disappeared. Poynton braces himself for a confrontation with Nell, who has already infiltrated the estate and is busy dispatching guards one by one, aided by Billy.
Outside, Devereaux, seeing an opportunity, decides to steal some money from the mansion's vast treasures. He convinces George to join him in this risky endeavor. Meanwhile, inside the estate, Roxy and Rasselas stumble upon Thomas, who is in a delirious state and mistakes them for ghosts. He reveals his true name, Amadin, explaining that Lord Blancheford changed it because he disliked it. Rasselas is enraged, but Roxy urges them to warn Nell of the danger within.
Elsewhere, Nell cautiously entered the chamber where the queen was bound to a chair. She wasted no time in loosening the ropes, but in another corridor of the estate, George and Devereaux stumbled upon another facsimile of the queen, similarly restrained.
The queen with Nell began to taunt her, mocking Nell's efforts. She shoved Nell roughly, and suddenly Poynton materialized, grasping Nell in a vice that even Billy's strength could not pry loose. Roxy desperately attempted to remove the necklace from Thomas' neck, and the false queen vanished, granting Nell the chance to retaliate. Poynton boasted of his grandiose plans, and Nell suggested they take their altercation outdoors, to which he grudgingly agreed.
Meanwhile, Sofia finally managed to break free from the confining bonds Poynton had wrought upon her. She dashed out, catching sight of Nell fleeing across the grassy lawn. Poynton stood before them, chanting an incantation that turned daylight into dusk. He knocked Sofia to the ground and engaged Nell in a fierce duel, spear versus sword. Sofia attempted to pelt Poynton with balls of fire, but they had no effect on him. His attention was briefly diverted when he spied the queen galloping away on horseback, but upon catching up, he realized it was Devereaux impersonating her once again.
Nell and Sofia retreated indoors, where Roxy and Rassalas revealed that Poynton's power originated from Thomas. Roxy urged them to flee with George and the queen, and the latter expressed her gratitude to Nell for her service. As Poynton made his way back to the house, Nell instructed Billy to enter Thomas and combat the darkness within him. Billy hesitated, reluctant to leave her alone, but Nell insisted it was their only option. They exchanged heartfelt farewells, and Billy flew into Thomas, commencing his battle.
Poynton's arrival was swift and menacing, as Nell valiantly attempted to engage him in combat. But without her powers, she stood no chance against his formidable strength. Just when it seemed Poynton was about to deliver the fatal blow, Billy unexpectedly emerged victorious. Thomas emerged from the clutches of the dark power, stripping Poynton of his own. The sun broke through the clouds, and Sofia lunged forward, piercing Poynton through with her sword.
As Poynton lay lifeless, Sofia turned to Nell, promising to inform the queen of Thomas and Sofia's role in defeating the villain. Nell, however, had lost too much and refused. She suggested they be allowed to flee, experiencing the hardships of being on the run. Sofia obliged, taking Thomas and departing.
Nell ventured out, reuniting with her beloved family. Some time later, Nell, Roxy, George, and Amadin (now going by his true name, Rassalas) received a formal pardon from the queen. Devereaux was even awarded a knighthood. Unexpectedly, the queen requested a demonstration of Nell's remarkable ability to catch bullets. With precision and timing, Nell halted the bullets in their tracks. The queen, impressed, offered her the esteemed position of Captain of her Guard. But Nell's heart was not in it; she desired a different path. Curious, the queen inquired about Nell's wishes. Nell inquired if the queen had ever heard of a tavern called the Talbot.
As the quartet made their way back to Tottenham, presumably to rebuild their home, a small golden light hovered towards Nell, marking the end of Renegade Nell Episode 8, leaving them with a glimmer of hope for the future.
