Episode 8 of "Washington Black" commences with a nostalgic glimpse into 1817, when Kit was still ensconced in the realm of Dahomey, an integral member of the King's esteemed female guard squad. A stringent regulation dictated that female guards remain childless, devoid of familial ties. Yet, Kit's heart was ensnared by a clandestine lover, causing her to disregard the cautionary words of her closest companion, Esi. Deep within her soul, Kit yearned to embrace motherhood.
Upon conceiving, Kit unburdened her secret to Esi, who promised unwavering support. However, the truth soon came to light, leading to Kit's harsh punishment: she was bestowed upon a colonialist as a penalty.
When Wash learns of Kit's true identity as his mother, he abruptly departs, leaving Gaius to attempt to elucidate Kit's motives. Gaius reveals that Kit concealed the truth to safeguard Wash, although Titch had always been privy to the secret. Wash, however, exits the conversation prematurely, leaving Gaius's further explanations unheard.
Later that evening, Gaius tracks down Wash, imparting more insights about Kit. Gaius, too, hails from Dahomey and had known Kit, who was known by her birth name, Nawi. He presents Wash with a detailed record of his knowledge concerning Nawi and her village of origin, urging him to visit. Additionally, Gaius hands Wash a recent missive from Titch, who resides in Morocco. Defying Tanna's objections, the duo embarks on a journey to Morocco in search of Titch.
In Morocco, they locate Titch, but Wash remains unsatisfied, as he had long sought answers to why Titch had chosen to abandon him. Their confrontation yields no solace for Wash. Conversely, Titch inquiries about his father's final words, to which Wash reveals, for the first time. Titch is moved by his father's wish for him to live authentically and cease seeking his validation.
Wash harbors concerns that Titch's latest invention, intended to facilitate lunar travel, might spell his doom. Titch implores him to stay and assist, yet Wash declines, departing with his questions still unanswered.
Does Wash successfully bring his aerial invention to life? Following their encounter with Titch, Wash and Tanna dedicate themselves wholeheartedly to perfecting their flying contraption. Months of relentless effort culminate in its completion. Just before embarking on their maiden voyage, Wash pops the question to Tanna, who joyfully accepts his proposal. They then utilize their innovative windsailer to embark on a journey to Dahomey.
Upon their arrival in Dahomey, Wash crosses paths with Esi and gains deeper insights into his mother's life. He learns how Nawi sacrificed everything to embrace motherhood. In a poignant moment, Wash encounters the apparition of his mother, Nawi, and achieves a heartfelt reconciliation with her spirit. The couple spends several blissful weeks in Dahomey, where Tanna welcomes their newborn daughter into the world, naming her in tribute to Wash's beloved mother.
How does the narrative of Washington Black conclude? As Tanna regains her vitality, she, along with her family, ventures to Solomon's Island to reconnect with her kin. The story wraps up with heartwarming cameos from various individuals from Wash's life, all sending him their best wishes as he soars through the skies. The family arrives safely on Solomon Island, where they are warmly embraced by the local community.
