Oh, one other thing about "City of Stone Part One" that I forgot to mention. One touch that I liked was the bit about Findlaech's declaration of loyalty to Prince Duncan. I particularly liked it because of the light that it gives to Duncan's having Findlaech assassinated: not only was it an evil deed, but it was also unnecessary. Findlaech really didn't have any plans to put Macbeth on the throne and outmaneuver Duncan. So Duncan would have become King anyway without needing to send the Hunter over to Castle Moray. In fact, by having Findlaech assassinated, he wound up moving one step closer to the very future that he feared (Macbeth becoming king in his place).

You might almost view it as a parallel to Demona's helping to bring about the Wyvern Massacre, partly to avert the vision that she'd seen in "Vows" (assuming that my suspicion is correct that Demona believed that the massacre had been carried out by Princess Katharine's people; as I mentioned before, the Demona from 1995 tells her only that the humans did it without saying which humans, which could make misinterpretation very easy). In each case, the very attempt that the character makes to avoid an undesired future helps to bring about that future. The old self-fulfilling prophecy business again. (And it crops up, of course, even more in Part Three).
