The following year, he and Methos, as Dr Benjamin Adams, met Claire Clairmont in Switzerland and traveled to a house Byron has rented for the season. They encounter Hans Kershner, on the road. Methos pulled his carriage to a halt as he and Byron sense the other immortal. Byron tells Methos that he slept with Hans's wife. After a brief chase, Kershner's carriage turns over, tumbling him to the ground.
Later Byron, Methos, Mary Shelly, Claire, and Percy Shelly are having a party with Byron reading his poems. The famous challenge for a ghost story from each of the guests is issued. The next night, Hans comes to Byron's house to challenge Byron. Methos tells his student he isn't ready yet, but Byron cannot be restrained. Mary watches the fight, until Kershner finally runs Byron through. But Byron yanks another sword from his cane and stabs Kershner, then beheads him with his primary blade.
Mary runs forward, shocked, as Methos catches Byron and lowers him to the ground. Then he grabs her and pulls her back away from the body as the Quickening begins. While Mary watches terrified, as lightning crawls over Byron's body, making his limbs twitch and lift. The Quickening fades, and Byron is alive again as Mary and Methos watch. She demands an explanation, and Methos tells her that they are immortal, but that it must remain a secret. Mary understands instantly: "Or you would be hunted." Methos agrees: "For the perversion of nature that we are."
Mary's compassion is roused, "Poor tormented creature. The sad hero of a never-ending story. Resurrected by lightning to eternal life. To eternal lonliness." From this beginning came the inspiration for her masterpiece, Frankenstein: The Modern Prometheus.
By 1997, Byron is a famous rockstar who uses any and all drugs to excess in order to stave off bordedom. He runs into Methos and Duncan at a club and meets Mike Paladini, a guitarist and protege of Joe's. Joe is amazed that Byron is the actual Lord Byron and that Methos had never mentioned him. Byron acts as a Siren song to Mike, however, and the young guitarist follows him home to become immersed in Byrons catostrophic drug habits, which kill Mike within days. Furious with the reckless waste of life and talent, MacLeod is determined to challenge Byron.
Methos meets Byron in his dressing room and warns him that MacLeod is coming for him, and advises him to skip town, but Byron refuses. Methos then tries to convince MacLeod not to destroy Bryon, "Mac, wait! Think. Think about the poetry. Think about the music that he's made. Think about the music that he will still make. You're going to kill all that as well?" MacLeod's only response is "And what about Mike? What music could he have made?" Methos cannot answer, and steps aside.
Byron accepts MacLeod's challenge and in the cellars of the venue, he loses his head to the highlander. Methos, unhappy, acknowledges that "His life had become one long tragedy." To which Duncan replies, "We all know how those end."
As the episode ends, we hear Byrons final epitaph. "My task is done, my song has ceased, my theme has died into an echo. It is fit".
Note: The music in episode attributed to Byron and his band was actually provided by Marcus Testory (who played Caspian) and his band M.E.L.T.
