In Episode 8 of "Bodies," Iris grapples with unforeseen challenges as she ventures to 1880. Determined to thwart Elias Mannix's malevolent intentions, she overlooks one critical detail – objects from the future can't accompany her back. Consequently, her SPINE, an advanced prosthetic enabling mobility in 2053, vanishes. Arriving in 1880, she's immobilized and eventually incarcerated.

Despite her plight, Iris strives to deter Hillinghead from confessing. Dispatching a message fails, but fate has them incarcerated adjacently. Iris divulges startling truths: Elias Mannix, alias Julian Harker, hails from the future. Moreover, the corpse discovered in Long Harvest Lane is temporally displaced. She implores Hillinghead to prevent Elias's impending marriage to Polly, further revealing Hillinghead's grim fate – alleged suicide en route to jail. Her plea culminates in desperation as authorities escort him away.

Julian Harker, meanwhile, disrupts the convoy, lobbying Hillinghead to greenlight his union with Polly. Hillinghead's revelation about Harker's time-traveling origins shocks him. Despite Hillinghead's forewarnings, Harker, now infuriated, instructs his entourage to execute Hillinghead. Yet, Hillinghead's last words sow seeds of doubt.

Harker's wedding proceeds, but Hillinghead's revelations linger. Confronted by Polly about her father's demise, Harker confesses, fracturing their relationship. Despite this, they welcome a son. Eventually recognizing his errors, Harker records a cautionary message for his past and future selves, particularly against detonating a device. Detective Whiteman receives this record but is promptly gunned down by Hayden's crew, avenging Polly and Harker. As he breathes his last, Whiteman secretes the vinyl behind a picture, reshaping destiny.

With the timeline altered, Hasan's recollections morph. Recognizing Whiteman's ploy with the recording hidden in the still-standing Silk pub, Hasan retrieves it. She rushes to Sarah, alerting her younger counterpart about Elias's impending disaster via phone detonation. Playing Harker's confession, Hasan convinces Elias of the haunting repercussions. In a poignant moment, Sarah embraces Elias, who mysteriously vanishes – a reset timeline erasing Elias's very existence.

"Bodies" concludes harmoniously. Whiteman and Hillinghead resume their roles across timelines, with the discovery of Defoe's body on Long Harvest Lane now irrelevant.

The episode's finale unveils a twist: Iris Maplewood, now able-bodied, chauffeurs Hasan to her father's birthday bash.

Despite "Bodies" courting narrative complexities, its final episode is undeniably a standout, masterfully weaving its intricate threads. The episode elucidates the multifaceted timeline but preserves an element of mystery. It artfully balances thrilling temporal twists with suspenseful climaxes, compelling viewers to ponder the series' layered events.
