This may not be the greatest acting by either Christopher Lambert or Adrian Paul, but it got the job done. Christopher Lambert was the mentor to Adrian Paul. They are both from the same clan, but when Tessa asks if they are related, they don't explain how the clan works. Are they distant cousins? Is Lambert (Connor MacLeod) the uncle from three generations earlier? It would have been nice if they just came out and said that they had a bloodline relationship.
Christopher Lambert always has a goofy look on his face, and he was intense in his first roles as Tarzan, and as Connor MacLeod in the original Highlander movie, but later on, he never seemed convincing in any role. Here he is not bad, just his usual self. Duncan MacLeod / Adrian Paul was originally a dancer and a model who was born in the United Kingdom and came to the USA to seek his fortune and fame. His acting is too intense for a guy who has been alive 400 years, but it was a good contrast to Christopher Lambert.
This episode should have been all about the two MacLeod's fighting the evil Slan (played very well by Richard Moll of Night Court TV series). The flashbacks were good, and the story should have focused on the two immortals seeing each other after a hundred years or so.
Unfortunately, the incredibly annoying Richie (Stan Kirsch) is introduced to the series. Richie is a never-ending magnet for trouble. He is a 17 going on 18 young adult with a bad attitude who also manages to make every dumb mistake that is possible, and always gets Duncan into trouble. Richie also seems to attract every evil immortal in town to Duncan MacLeod, who has to fight all the battles that are started by Richie.
Tessa Noel is played by Alexandra Vandermoot as a non-stop nagging harpy who wants to be involved in every moment of Duncan's life, and wants to control every decision he makes. Why is Duncan so insanely in love with her? I guess he likes to be miserable, and that would also explain why he adopts Richie into his life? Tessa and Richie really drag this episode down every time they are in it.
Overall, the combination of Christopher Lambert and Adrian Paul is entertaining, and Richard Moll does a very good job as a menacing evil character.
