Episode 6 of "Washington Black" commences with an intense scene of Billard hot on Jack's trail through the dense woods. Jack, ingenious and resourceful, has crafted a wooden trap, which unfortunately catches Billard off guard, injuring his leg in the process. The relentless pursuit intensifies, leading the adversaries to the precipice of a cliff. Meanwhile, Medwin and Tanna stumble upon Billard's abandoned carriage and meticulously follow the trail, Tanna clinging to the hope that Jack is still alive.
At the cliff's edge, Jack faces a harrowing dilemma. He decides to make a dramatic stand, vowing to take Billard down with him into the abyss below. Jack declares his freedom, even in the face of impending doom. As they plummet into the sea, Jack's consciousness wanes, and he encounters a vision of his younger self. His adult self, filled with regret, apologizes for abandoning their shared dreams. The youthful Jack, resilient and determined, urges him to fight against the currents and swim to safety.
Amidst these visions, Jack catches a glimpse of Tanna's face, which snaps him back to reality. With renewed determination, he begins to struggle against the waves. Simultaneously, Tanna discovers Jack's necklace at the cliff's edge, and she and Medwin scan the shoreline for any sign of him. To their horror, they find Billard's lifeless body and Jack clinging precariously to life.
They rush Jack back to the safety of Angie's home. She reprimands Medwin for jeopardizing his life without her knowledge, but their reunion is cut short when Medwin hesitates just as their lips are about to meet. Angie, puzzled and hurt, demands to know why he is pulling away once more. Elsewhere, Tanna tends to Jack, her actions a testament to her unwavering care. After ensuring his well-being, she seeks out McGee, who generously agrees to forgive her family's debt and terminates their engagement.
The narrative shifts back to a chilling flashback in the Arctic, following Titch's devastating fall. Assuming the worst, Jack fears Titch has perished. Wilde's unexpected arrival brings a ray of hope as he swiftly administers first aid. Once Titch regains consciousness, Wilde guides them to his igloo camp. Jack marvels at the intricacies of ice houses, a world entirely new to him. As they settle in, Titch's heart sinks upon witnessing his father with his lover, Peter. Peter, deaf and communicative through sign language, captures Jack's fascination.
Wilde reveals his mission to study the Northern Lights, his curiosity piqued by Jack. Titch, however, feigns exhaustion, eager to avoid further conversation. Despite this, Wilde extends an invitation for a seal hunt the following morning. Jack, sensitive to Titch's emotional turmoil, inquires about his silence regarding Philip. Titch, avoiding the subject, retreats to bed, leaving Jack to ponder the depths of his friend's pain.
The following morning, the group, accompanied by two locals, embarked on a seal hunt, an adventure that provided Titch with the perfect moment to recount the triumph of the cloud cutter to his father. However, instead of pride, his dad responded with stern rebuke for involving Jack in the perilous Arctic expedition. Titch, undeterred, confronted his father about his staged death and his enigmatic connection with Peter. Wilde, steadfast in his conviction, declared that living a lie was both disgraceful and sinful, expressing his resolve to no longer sacrifice his own happiness for the sake of his family.
As the hunt intensified, an unforeseen tragedy unfolded when Twitch, in a moment of carelessness, inadvertently struck Peter in the leg with an arrow. In the aftermath, Titch attempted to offer his apologies, only to be met with further scolding from his father. Wilde, unburdening his soul, confessed that it was he who had thwarted Titch's admission to RSL. According to Wilde, Titch lacked the scientific prowess and posed a danger to those around him, Jack included. These words pierced Titch's heart like a dagger.
Meanwhile, Jack found solace in the company of the two locals, who were mourning the loss of their daughter. He shared stories of Kit, and they bonded over their mutual grief. That evening, Titch awoke Jack and handed him a letter of freedom, along with some money. Despite Jack's pleas for Titch to stay amidst the raging storm, Titch insisted on leaving, branding Jack as a burden and walking away. Frustrated and desperate, Jack cursed Titch after his repeated begging fell on deaf ears.
By the time Jack realized his solitude, he was already too far from the igloo, blinded by the ferocity of the storm. Calls for help echoed through the wilderness, as Jack struggled to make sense of his plight.
