This was an exceptional episode and was a welcome relief from many of the early B-5 shows, as most of the very early ones were more "time fillers" than part of the over-arching plots that made this show one of the greatest sci-fi series ever. Now in episode 6 you could finally start to see some of the plot threads necessary to later episodes start to appear. Plus, it just so happens that my all-time favorite character from the show is seen for the first time--"Bester". Walter Koenig ("Chekov" from the original Star Trek) was just great as the slimy, egotistical and darkly evil Psi Cop and in this episode he seems less awful than he will be in later shows. But this slow unfolding of characters is one of the best things about this show and having Bester and many of the characters from earlier shows re-appear in later episodes help to give the show an almost epic movie quality--like it's all one giant tapestry. See this one and see how the Bester character was from day 1. An excellent episode.
