They Also Serve Highlander : Season 3 Episode 12

Recent Immortal Michael Christian has been on an incredible string of luck, taking a number of heads from unarmed and vulnerable opponents, including May-Ling Shen, who taught MacLeod the martial arts in 1780's Mongolia. Christian's Watcher, Rita Luce, has been doing more than just watching, supplying Christian with classified information on the other Immortals and their weaknesses. MacLeod, unaware of Christian, goes on a vision quest to his cabin on Holy Ground -- deliberately leaving his sword behind. The race is on for Joe Dawson to figure out Rita's secret before Christian sets his sights on MacLeod.
