Doctor Who: Peter Davison Again the Doctor is plagued with difficulties in regenerating, though it has never been so severe as this. To fully complete the regeneration process after such a traumatic event, the Doctor needs to be placed inside the TARDIS's Zero Room, and area of total isolation from space and time. Unfortunately, the companions of the Doctor are forced to jettison a large portion of the TARDIS to escape the massive gravity of a dying star, and the Zero Room goes out with the lot. As a result, the fifth Doctor spends most of the episode of "Castrovalva" in a high level of unstability. He recovers fully in the end, though, and goes on through what has to be said is a sort of "pause" in the continual action of the Doctor. Davison wove an interesting character in the short time he played the Time Lord. No longer brash, arrogant, and outgoing, the Doctor's fifth regeneration seemed more introverted and thoughtful. His voice was not as booming and commanding, and his words were thought out before spoken. I have heard others comment on how this Doctor seemed so depressed, but I beg to differ. I see it as a well-timed pause in the high speed exploits that had become so common. It was time for the series to stop and take a deep breath, look upon itself, and consider what it finds within. So many of Baker's episodes before Davison's time were getting to be more of the same good-guy-versus-the-evil- alien-monster type thing, and so it was nice to see a change to the somewhat slower, more thought promoting years of Doctor five. His trademark is the cricket bat and ball, a sport which the real Davison was so fond of, and one which he gets to take part in the series. Time, even for the Doctor, must roll on though, and after contracting Spectrox poisoning in the episode "The Caves of Androzani", he undergoes his next regeneration.
