Having watched every episode and discussed the show in full, how can Ian and Dave bring their episode count up to 30? By discussing two Blake's 7 radio plays from the 1990s, of course. In "The Sevenfold Crown," the Scorpio race to beat Servalan to a crown that will give the wearer phenomenal cosmic power. In "The Syndeton Experiment," Avon's attempt to bring the fight to the Federation leads the crew to a mad scientist and his army of three-legged purple robots. They also discuss why the word "hyperdrive" makes Dave so annoyed, try to picture how a wolf-snake would work, and announce their next podcasting project.

Their journey has ended, so it's time for Dave and Ian to sit down and take stock of everything they have seen and shared over the last couple of years in an epic-length overview. They go through Blake's 7's best and worst episodes, discuss what the writers brought to the show, choose their favorite guest characters, and Statistician Ian returns for a roundup of grand totals for the bracelet and Who counts. Join them on this trip down memory lane, complete with a new jingle.

After two years and 27 episodes, Ian and Dave finally reach the very last episode of Blake's 7. In "Blake," the Scorpio crew have destroyed Xenon base and are on the run. In a last-ditch attempt to try and establish a united resistance against the Federation, Avon takes the Scorpio to the lawless planet Gauda Prime where he believes he will find the only person who can be their figurehead: Roj Blake. They also look back at the highs and lows of series four, discuss why Blake is terrible at explaining himself, and why Slave is the most meta character in the whole show.

Dave and Ian enter the final phase of Blake's 7 before the series finale. In "Orbit," Avon is offered the ultimate weapon in exchange for ORAC. While Avon is unwilling to part with the ultimate computer, he is willing to dispose of Vila, when he becomes the only thing between Avon and escape. In "Warlord," Avon tries to rally leaders from non-Federation territories into a united resistance force. The only things standing in his way are the machinations of Servalan and Tarrant's libido. Dr. Stuart sends Dave a small essay to read, they decide that no good can come from Tarrant's penis, and revel in the adventures of Rafiki Stardust and the electric goblets.

Ian and Dave return with a mixed bag of Blake's 7 this month. In "Sand," the Scorpio crew and Servalan travel to a planet which might contain a valuable new resource. The resource turns out to be sentient sand with a rudimentary knowledge of basic farming techniques. Can the crew overpower evil sand? Why are we even asking that question? In "Gold," an old acquaintance of Avon's asks for help to steal a fortune in gold from a luxurious cruise ship, but who is really pulling the strings? They also discuss Tarrant acting stoned, the actor Peter Craze, Dave gets to channel Marvin Gaye again, and who in their right mind would think that an episode where the villain is some sand was a good idea?

Dave and Ian have recovered from the festive season and are back with two more episodes of Blake's 7 to discuss. In "Assassin," the Scorpio crew discover that Servalan is trying to hire the notorious assassin Cancer to kill them, so they decide to try and get to Servalan first. In "Games," the crew try to steal a valuable mineral supply from under the nose of the game-obsessed Belkov and a bored-looking Servalan. They also discuss deadly geometry sets, classic light gun games, get sidetracked by nostalgia, and, apropos of nothing, verbally abuse Ian's brother.

In their last show for 2012, Ian and Dave watch two more episodes of Blake's 7. In "Animals," Dayna tries to recruit a scientist but discovers his obsession with creating cosplay yetis with comedy horns. She then gets brainwashed by Servalan in what becomes a pretty bad day. In "Headhunter," Avon tries to recruit a scientist but discovers the scientist has been killed by his own creation and is walking about wearing his head. Avon then gets electrocuted in what also turns out to be a pretty bad day. They also get an alternative newcomer's view of the show, the Orgs increase their feedback, and there is gratuitous use of the phrase "wank trifle."

Dave and Ian continue to make their way through the final season of Blake's 7. In "Traitor," Tarrant and Dayna are sent to investigate how the Federation is expanding so quickly. They discover that a new drug and an old enemy are responsible. In "Stardrive," the crew come to the conclusion that the Scorpio's engine sucks and decide to get a new one. Unfortunately the one they have their eye on is in the possession of the psychotic Space Rats and their improbable hair. They also ask important questions like, which character had their worst week ever between episodes? Why does the Scorpio have a rear viewscreen? And how do you get a crash helmet over a foot-high mohawk?

Ian and Dave begin the final leg of their Blake's 7 journey as they enter series four. In "Rescue," the crew are, well, rescued by the mysterious Dorian who has a lot of cool stuff that they would find really useful if only he would turn out to be insane and then drop dead. In "Power," the crew have to figure out how to help themselves to all of Dorian's cool stuff after he turned out to be insane and then dropped dead. Plus, they encounter a repurposed Doctor Who monster and a dancing judge, get introduced to a new regular character and then debate where the hell she vanishes to in her second episode.

Dave and Ian reach the end of season three of Blake's 7. In "Terminal," Avon, acting under instructions from a mysterious source, takes the Liberator to an artificial planet thought long destroyed. His haste to get there has a terrible price for the Liberator and its crew, and his arrival has been anticipated. They also look back over the highs and lows of the third season, receive some more medical knowledge from Dr. Stuart, and nearly wear out their dramatic music sting. Stay tuned after the credits to hear the trailer for the forthcoming Blake's 7 audio drama "Warship."
