This episode sees a pair of suspicious characters arrive on Babylon 5; they start asking people about members of the command staff; in particular Commander Sinclair. At first it looks as they may be involved in illegal arms deals but when confronted it emerges they are Colonel Ari Ben Zayn and Harriman Gray, part of Earthforce Internal Affairs, AKA Eyes, and they intend to investigate the actions of the senior staff and telepathically scan then to ensure their loyalty... a procedure Lt Commander Ivanova absolutely refuses to undergo. In a secondary, minor story Lennier offers to help Garibaldi restore a classic motorbike.
I found this episode to be rather enjoyable; it starts well with some nice misdirection as the viewer is encouraged to assume Zayn and Gray are arms dealers before their real identity emerges. The way the investigation progresses creates an oppressive feel with the series three main human characters being targeted in what appears to be a witch hunt; for reasons that will ultimately be revealed. Gregory Martin does a solid job as Zayn even if, partially thanks to a large facial scar, his character becomes a bit of a pantomime villain. Jeffrey Combs is impressive as Gray; a character who is more nuanced than most members of Psi-Corps we have met so far. The secondary story involving Garibaldi's motorbike is a fun balance to balance to the main story.
