1x14 - Highlander: The Raven

Two of Bert's bodyguards are protecting a flighty actress when one is shot and killed. Nick is called in, and prevents another apparent assassination attempt, only to realize the assassin is a man, Frank Brennan, that he killed four years ago. In flashback we see how Nick and Bert met for the first time, when Nick inadvertently rescued Bert when Brennan, a rogue NSA agent, tried to kill him. Brennan isn't after the actress, but rather the people involved in his first ""death"" which made him immortal, and who are now guarding her. Amanda and Nick manage to thwart Brennan before he can kill Bert, while keeping the secret of Immortals away from Myers. Amanda confronts Brennan, who shoots her. Nick shoots him and Amanda takes his head. Copyright 2002 Steve Crow
