Highlander: The Series - Season 3 Episode 8

Immortal David Keogh, once an indentured servant, is a noted craftsman with his heart set on marrying his sweetheart, Jill. Unfortunately, Jill does not agree. Although she loved Keogh once, she was unable to handle it when he confided the secret of his Immortality. Now Keogh won't leave her alone and she's coming to MacLeod, whom Keogh respects and might listen to, for help. But Keogh won't listen, convinced that Jill needs him as much as he needs her. In flashback, we see a time in MacLeod's life when he, too, was obsessed with a woman he couldn't have. When Jill is killed in a tragic accident while trying to get way from Keogh, Keogh blames MacLeod and swears vengence.
