Introducing Bester and the Psi-cops
3 June 2018 | by TweekumsSee all my reviews

As this episode opens a stolen ship is approached by fighters but manages to escape; its destination is Babylon 5. Shortly afterwards two Psi-cops, the Psi-Corps police who enforce their rules on telepaths arrive on Babylon 5. They are looking for Jason Ironheart; the man on the stolen ship who was previously Talia Winters trainer and lover. Bester, the senior Psi-cop declines to say why they want Ironheart but he does expect full cooperation. They scan Talia to ensure she hasn't been contacted by Ironheart; shortly afterwards he does make contact and tells her why he is wanted. If he is to be believed the Psi-corp present a grave threat to everybody. Elsewhere Catherine Sakai has been contracted to survey the planet Sigma 967; it is in Narn space and G'Kar warns her against going as 'strange things happen their' she ignores him and learns just what he meant.

This was a great episode, possibly the best so far. The highlight is the introduction of Bester and the sinister Psi-cops. Walter Koenig does a great job in this role; he makes his character arrogant without becoming annoying and quietly menacing in a way that seems believable... he may be best known as Star Trek's Ensign Chekov but Bester is the better role! The main story tells us more about telepaths in general and the operations of the Psi-corps and the Psi-cops in particular. Ironheart was an interesting character; dangerous but not obviously malicious. William Allen Young did a solid job in the role. The secondary story might not have been as important to the episode but it opened details that could prove very important... until now it appeared that the species we see on Babylon 5 are the galaxy's dominant life forms; this suggest that there may be other beings beyond our comprehension; so far advanced that they would look on us the way we look at ants. Overall this was a great episode; both because of what it included but also because of hints of what might come later regarding the Psi-cops and the beings that may dwell near Sigma 967.
