We finally viewed the end of the Omega arc in “Arc of Infinity.” I was actually a bit surprised at how much I enjoyed this episode, since the first one, “The Three Doctors,” was rather weak – it involved way too many crazy dictator enemy rants, minor characters complaints, and wandering corridors/wilderness fillers to be involving. Even the bickering between the Second and Third Doctors couldn’t save that episode.
“Arc of Infinity” had a lot of incomprehensible technobabble, since it involved another Omega plot to return to Gallifrey from the antimatter universe, and that was a bit difficult to follow. It’s main strength was the part of the plot set on Gallifrey. The High Council detected that something from the antimatter universe was trying to enter N-space and that it was using the Doctor’s biodata to do so. In order to break the link, they ordered the termination of the Doctor, even though the Doctor pointed out to them that the only way the entity could get the biodata was if someone on the High Council was helping it. Thus, a lot of the plot had to do with political maneuvering among the council members and the Castellan’s investigations into the matter.
Omega’s plans involved coming through to N-space on Earth, so part of the story involved two hitchhikers who inadvertantly get involved. This drew in Tegan, who had returned to her normal life and was visiting her cousin, one of the two hitchhikers. Thus, when Omega finally did make it through, he appeared in Amsterdam, in the form of the Fifth Doctor. (Two Peter Davisons! Twice the awesome in one episode!) Up until this point, Omega had been portrayed as he had been in “The Three Doctors”: insane, megalomanical, and desperate. As he starts to roam in Amsterdam, he observed the day-to-day lives of the people, and smiled, the implication being that his joy in being home actually was overcoming his insanity from thousands of years of isolation. This was a very interesting character development, which unfortunately truncated because his Fifth Doctor body began to decay and needed to be destroyed before he turned back into antimatter and exploded. This was the only bad part of the episode: once Omega realized that he was reverting to antimatter, he began running from the Doctor (who was trying to destroy him before he exploded and destroyed the earth). Apart from the question of why he would run, since he was doomed and there wasn’t anywhere to run to, the running sequence took about fifteen minutes – way too much filler. If instead they had used the time to explore Omega’s return to sanity and had him face the fact that he had to be destroyed or returned to the antimatter universe (and/or have the Doctor realize that he had to destroy a now-sane individual), this would have been a superb episode.
All in all, though, it was a fun episode, and the Doctor got to have some great interactions with the Time Lords, which is always a treat. Nyssa got the chance to shoot a few people, and Tegan rejoined the crew of the TARDIS. The one thing that would make Omega’s arc great: a new episode in which Omega returns, played by Mr. Davison. It’s been established in the audio plays that Omega survived this episode in the Fifth Doctor’s form, so it is possible. Come on, Steven Moffat, do it!
