The one where the Master gets a new body at last...
It's a real rollercoaster ride trying to work out whether the Doctor knows Melkur is the Master or not. As a viewer, we were given a strong hint at the end of part 3 when the man inside Melkur turned to camera and looked pretty much like the Master the last time we saw him (The Deadly Assassin). But that was not definite, and seeing as The Deadly Assassin was over four years previous, lay viewers could be forgiven for not getting the connection.
As early as part 2, the Doctor says: "So you're the cause of all this" when he hears Melkur's voice (he knows!) but it transpires he was just referring to Melkur (he doesn't know!). In part 3 Tom Baker puts some heavy emphasis on "master plans" in reference to the Source Manipulator blueprints (he knows!), but it was just a coincidence it seems (he doesn't know!). And at the start of part 4, the Doctor warns Luvic that he should do what Melkur tells him to or "he'll make you" (he knows!), but then states that his only ambition "is to stop you, Melkur!" (he doesn't know!).
