Season five was originally intended to be the final season in the series. But towards the end of the season, the show was renewed for a six year. By he time this happened, many of the stars already had other commitments to other projects so were only available for a short time. The series concluded the Arihman story arc in the first two episodes. Episodes 3, 5, 8, 9, and 10 dealt with female Immortals, some whom Duncan encountered and others he didn’t. The producers were experimenting, looking for a replacement for the Highlander in the planned spin-off Highlander :The Raven. Only episodes 4, 6, 7, 11, 12, and 13 felt like regular series episodes.
