Ian Wilson fights through his flu to join Dave Probert for two more episodes of Blake's 7. In "Mission to Destiny," Avon and Cally hunt a murderer on a sabotaged ship while the Liberator embarks on a mercy mission. And in "Duel," Blake and Travis are forced into a fight to the death by ethereal beings who have clearly watched the Star Trek episode "Arena." They also discuss religions based on The Shawshank Redemption, a Blake's 7 version of The Benny Hill Show, and Ian is greatly disturbed by a picture of a 1970s Doctor Who monster. Which one? You'll have to listen to find out.
