Hero
Three Cylon fighters appear near Galactica, but rather than attacking the Colonial fleet, two of the Cylons are trying to destroy the third. Starbuck and Kat take out the two pursuers, but Adama orders them to stand down when a human voice is heard over the speakers, identifying himself as “Bulldog.” The Cylon ship is brought in for a landing on Galactica, and a human male tumbles out of it – Adama recognizes him as Bulldog, a pilot Adama selected for a top secret mission (and wound up abandoning when his fighter was shot down) over a year before the Cylon attacks on the Colonies. When Bulldog pays a social call to his old friend Tigh, who’s still off-duty, Tigh reveals the real nature of Bulldog’s mission. Adama confesses the same to his son, admitting that Bulldog’s real mission was to determine whether or not the Cylons were still out there and preparing for a strike on the Colonies – and that his capture by the Cylons could have been the event that sparked the attack that came later. Adama confesses that he feels the weight of responsibility for causing the attacks that nearly wiped out humanity. And analyzing the desperate flight that brought Bulldog back to Galactica, Starbuck begins to warn her superiors that she thinks it’s no accident that the lost hero has returned home.

LogBook entry by Earl Green
The TARDIS deposits the Doctor, Ace and Hex in harm’s way on the front lines of World War I. After a close call with a German shell, they wind up in a makeshift military hospital, and as soon as the Doctor is fully recovered, he’s startled to find that there are orders awaiting him: they ask the British commanding officer to accord the Doctor and his associates full access to the hospital in order to investigate a murder that has yet to happen. Completely mystified, the Doctor begins investigating, but not before Hex warns him of one disturbing possibility: the future murder victim could be one of the time travelers. Hex discovers first-hand that horrifying experiments in mind control are taking place at this hospital, far ahead of their time, and crude – but effective. The Doctor and Ace find themselves on the receiving end of a none-too-subtle warning about poking around where they’re not welcome. They find an ally in a man who’s being kept off the front lines for fear that his pacifistic views will send him running into the arms of the enemy, but with the rest of the soldiers turned against him, he can’t offer the Doctor much help. When the murder finally takes place, however, it seems that the base commander has his own ideas as to who should face the music for the killing, whether his suspicions are founded in truth or not. But who knew about the murder ahead of time?

As always, war rages on, ravaging the surface and the people of Skaro. The emphasis turns to espionage as a technological stalemate takes hold; so long as neither the Kaleds nor the Thals gain a decisive technological advantage, the war remains on a knife’s-edge detente that leaves the combatants with surgical strikes via conventional weapons. Davros is naturally working on new technology, but to the Kaled Supremo’s distaste, Davros is focusing solely on genetic engineering instead of devastating new weapons. Obsessed with the future of the Kaled race in the increasingly toxic and radioactive atmosphere, Davros – despite his debilitating injuries and being restricted to a mobile (but still very limited) life support base – is working toward providing a tank-like travel shell that will protect what he predicts the Kaleds will become, as well as allowing its occupant to defend itself. But the Thals are keenly aware that the best chance the Kaleds have of gaining an advantage in the war is Davros, and a commando unit raids the Kaled science dome to kidnap him. Separated from his life support chair, Davros is dying, but refuses to surrender any information, except the truth that he is not developing new weapons at this time. A Kaled strike team, led by the ambitious young Lt. Nyder, rescues Davros and brings him back to the Kaled capitol. Once recovered from his ordeal, Davros is finally ready to complete his rise to power…and all his people have to do is surrender their future to his great plans.
