|The Watchers (episode)|
MacLeod, Tessa and Richie settle back into the antique shop in the United States. Following a clue written by Darius on the Fifth Chronicle, MacLeod finds Horton's bookshop and meets Joe Dawson, Horton's daughter, Lynn Horton (Kehli O'Byrne), and her fiancé, Robert Tucker.
Dawson explains the Watchers to MacLeod, assuring him they are observers not killers. MacLeod then follows Dawson to find Horton. When Robert Tucker considers leaving the Hunters because MacLeod spared his life, Horton kills Robert.
Accompanied by Dawson and Lynn, MacLeod confronts Horton, who admits to killing Darius and Robert. MacLeod stabs Horton but Horton shoots him dead. When MacLeod revives, Dawson, Horton and Lynn have disappeared.
In a storeroom Joe Introduces Duncan to relics of Immortals: A shot glass used by a drunken Immortal gambler until he lost his head; a tomahawk used by a Native American Immortal for three generations; and a beheading Axe owned by Moutain Man Inmortal Caleb Cole used by Duncan to defend Tess.
One continuity issue for Highlander: The Series. Joe Dawson appears clueless of the rule regarding Holy Ground, believing that Darius was killed by an immortal. In a later episode, Little Tin God, Dawson relates a story of immortals battling it out in AD 79 in Pompeii, implying that the Watchers did know of the rule regarding Holy Ground. (Perhaps Dawson was ignorant of the rule initially but this encounter might have made him study more and learn. His comment on immortals fighting on Holy Ground happens many years after the events in this episode.)
When the Watcher bookshop was compromised by MacLeod's knowledge of it, the Immortal returns to find all signs of Watchers including the Chonicles and computer files have gone. Much the way Adam Pierson/Methos does a bunk in the episode Methos once he assumes his cover is blown. SOP for Watchers apparently.
Horton is later killed by MacLeod in episode 2-22 May 23, 1994 Counterfeit: Part Two
