The final five episodes of
Babylon 5's third season were originally shown in England from August 19 to September 22, 1996, but the American syndication service PTEN did not wish to "throw away" these episodes during the low-rated late summer months. Thus, viewers in the US did not see the season's final story arc until September, beginning with the telecast of "Walkabout" during the week of September 30, 1996. Written by J. Michael Straczynski, "Walkabout" finds Captain Sheridan and telepath Lyta Alexander (Patricia Tallman) preparing to exploit the Shadows' newly-discovered "achilles' heel" to mount a counteroffensive against the enemy. Meanwhile, Dr. Franklin heads DownBelow to determine his true purpose in life. Erica Gimpel appears as Cailyn, a beautiful singer who will have a profound effect on the introspective Franklin. ~ Hal Erickson, All Movie Guide
