    It's a high energy, satisfying conclusion

    So Hedin has been destroyed, and Omega has gained control of the matrix, the Doctor must escape Gallifrey to stop Omega's plan to transfer and return to Gallifreyan Society. The Doctor speaks to Tegan in the matrix and discovers their Dutch location. Omega begins to transfer, Nyssa and the Doctor are on foot seeking the location Tegan gave him. The Doctor's intervention is too late, Omega has transferred, but is he stable?

    It's possibly the best of the 4 parts, it is so refreshing to see the streets of Amsterdam used as a location, the trams, the river etc.

    I like the effects of Omega's transfer, it looks quite effective. Finally, the last of the Ergon, never to be seen again.

    The scene of Omega stopping and enjoying the barrel organ is a particularly effective one, is Omega a reformed character?

    There is a fair bit of running around, but at least it's purposeful, and not down corridors, there's lots of energy from all concerned.

    The finale is a satisfying one, as we see the Doctor defeat Omega and save the day, and Tegan's back on board, joy.... for some.

    Part 4 gets 8/10

    Storyline

    • Trivia
      Filming in Amsterdam proved problematic, with crowd control being a major issue. In many instances, Peter Davison drew the attention of Dutch viewers, because they recognised him from his role as Tristan Farnon in All Creatures Great & Small (1978). John Nathan-Turner tried to assist Ron Jones in dealing with the onlookers, and he is indeed is visible in the transmitted episode shooing away a group of gawkers in the background of the scene in which the Doctor and Nyssa use a telephone box. At one point, Nathan-Turner's attempts at crowd control became dangerous when an elderly woman assumed he was a thief and attacked him. On another occasion, several members of the cast and crew decided to take a walk around Amsterdam. Unfamiliar with the city, they suddenly found themselves in its infamous red light district, where Janet Fielding was mistaken for a prostitute.

      The Castellan, Maxil, and the other guards disappeared from the room after Hedin was shot, even though there was no indication that they were leaving, and they would in fact have remained to question the Doctor, Borusa, and Nyssa.
