That hardly sounds in character.
Each new Doctor’s inaugural tale must fulfill two objectives, often at odds with each other. In addition to providing a rousing introduction for the new title character, one that establishes a tone, an arc, for the adventures to come, the story must still function as a narrative whole, placing the new Doctor in some engaging situation that puts the fledgling Time Lord’s fresh attitude to the test. Not all of Doctor Who‘s post-regeneration stories work as well as others, and Colin Baker’s proper debut as the Sixth Doctor, in Anthony Steven’s “The Twin Dilemma” (Story Production Code 6S) doesn’t quite deliver the comprehensive punch of, say, Jon Pertwee’s “Spearhead from Space,” which introduced the Third Doctor in as compelling a tale as possible.
In part, this narrative disconnection comes about because producer John Nathan-Turner and script editor Eric Saward seem intent on telling one long story with their run on Doctor Who. Most other Doctors take over at the beginning of a season, with months passing between the prior Doctor’s regeneration and the new Doctor’s first real appearance, separating the audience from their memory of the predecessor. Here, Colin Baker assumes the role in Season Twenty-One’s final story; only six days pass between the Sixth Doctor popping up with a burr under his saddle at the end of “The Caves of Androzani” and the first episode of “The Twin Dilemma.” Having built the Fifth Doctor’s story as a continuous slide into ruin and despair with the first six stories in Season Twenty-One, Nathan-Turner and Saward seem intent on directly addressing the trauma they caused by inducing a regeneration crisis in the Sixth Doctor that leaves him initially with no discernible character at all.
Such a character-driven focus can pay real narrative dividends, and a more daring approach might have seen this as the sole focus of a story, a tight two-episode tale along the lines of Season One’s “The Edge of Destruction,” where the TARDIS crew turns on each other in an existential fugue, revealing far more of their true identities than any encounter with a Dalek ever could. But as with Peter Davison’s initial story, “Castrovalva,” Nathan-Turner’s concept of the “regeneration crisis” in “The Twin Dilemma” starts out strong and then flounders as the “action” part of the plot fails to keep pace. For once again, the notion of magical sums comes into play.
Two precocious, mathematically gifted twins, with the unfortunate names Romulus and Remus (Gavin and Andrew Conrad), disappear from their home on Earth, kidnapped by Professor Edgeworth (Maurice Denham), who seeks to harness their genius in order to move planets. Adric, it might be noted, similarly found himself trussed up in a skien of webs in the Master’s TARDIS in “Castrovalva,” his own calculation skills used to power the “block transfer equations” that create the mysterious town of the same name out of sheer nothingness. Much of beginning of “The Twin Dilemma” establishes the twins and the efforts of the Earth authorities to rescue them, padding out the story by introducing characters never seen again, save Lieutenant Hugo Lang (Kevin McNally), whose squadron of space fighters explodes while chasing Edgeworth’s space freighter to the asteroid Titan 3.
The Sixth Doctor, inevitably, turns his sights on supposedly abandoned Titan 3 as well, seeking a hermitage in which to recover his senses; the Fifth Doctor obviously never replaced the TARDIS “Zero Room” he retreated to (and then ejected) during his own regeneration crisis. His behavior immediately after his regeneration veers wildly—madly, even—at turns irascible, cowardly, brash, and, in a frankly shocking twist for the character, violent. Throughout “The Twin Dilemma,” the Sixth Doctor, and indeed Nathan-Turner behind him, seems to be daring the audience to dislike the Doctor. By the time he accuses Peri of being an alien spy and pushes her to the ground, throttling her, one might well say he succeeds…
