Though there's no Gerard, "Glass Tightrope" is a great episode, probing at what makes Kimble tick. The continued use of William Conrad's narration as Kimble's inner monologue is especially effective - why should Kimble risk his freedom for the wino who stands accused of murder? He sees a chance to save someone from his own fate. It's also a change of pace - unlike other episodes ("See Hollywood and Die," "Fatso"), Kimble is coming to the aid of a total stranger. The two men don't exchange a single word. It's more insight into the character of Kimble - if he can help it, he won't allow even a stranger to suffer.
It's always a hoot to see a young Leslie Nielsen in his dramatic acting days, long before "Airplane" and "The Naked Gun." Nielsen is terrific as Rowland, the man who kills in a fit of rage and then is tortured by conscience and domestic pressure as he remains silent. He's trapped too, just as much as Kimble is. For Rowland, howver, relief comes with accepting his sentence. Kimble must always elude that to even have the chance for relief.
Edward Binns is a nice foil as the hard-boiled store detective, a man who sees catching Kimble as a way back to the force. Like Kimble and Rowland, he feels trapped in his current situation. Watch the scene where he offers an old police colleague a store discount on neckties and is rejected.
It's not as powerful as the previous episode, but "Glass Tightrope" shows the "Fugitive" formula firing on all cylinders. A good script and great guest stars make all the difference.
