But anyway... Part three is all about revelations. The Doctor's not dead! Hedin is the traitor! The Renegade is Omega! Er... bringing back a one-time villain from ten years ago doesn't seem like a great move (even allowing for the fact that The Three Doctors was repeated in November 1981 as part of BBC2's Five Faces of Doctor Who season), and Arc of Infinity makes few concessions to anyone who doesn't remember/know about Omega. Not that it really matters, I suppose; all you need to know is that Omega really wants to take over the Doctor's form and enter our universe, and that This Is A Bad Thing, because Omega is made up of antimatter and thus will create a huge explosion when he interacts with matter. Again, how has Omega not considered this problem? Moreover, no one on Gallifrey seems willing to work with Omega, to come up with a safe way for him to transfer over; they'd much rather annihilate him and be done with it.

But of course it can't last; the transfer is unstable, and the Doctor is forced to dispatch Omega with a matter converter so that a huge explosion doesn't take place. The universe is saved, and Tegan is free to travel with the Doctor again. Although I can't tell if that final shot, where the Doctor smiles and then his face falls, is because the camera didn't cut away soon enough, or if the Doctor is meant to be somewhat less than enthusiastic about the prospect of traveling with Tegan again...
I can't decide if Arc of Infinity ultimately works or not. It's never less than entertaining, but there is a bit of a sense of the author's hand behind things; there's a good deal of technobabble floating around to make the story do whatever is necessary, and it's never really made clear what the main problem is. There's some handwaving about antimatter, but that's treated as if that's enough, and the threat Omega (allegedly) poses is thus frustratingly vague. It is, however, a story that works a bit better the second time around; if you already know that the Renegade is Omega, then you can have some fun with the motivations and the casual callbacks to facts we learned in The Three Doctors. But taken in context, Arc of Infinity is something of an unmotivated adventure, and while it's enjoyable enough while it lasts (and again, Peter Davison really is impressive as Omega), it's hard to dispel the sense that this is all rather irrelevant.
