The Edge of Destruction
I think Inside the Spaceship (editors note: alternate name for Edge of Destruction) tends to be overlooked or taken for granted by fans; itÂs a two parter shoved between the first Dalek story and the first (and now legendary due its missing status) historical, it was written to use up spare episodes in the season, the TARDIS nearly gets destroyed because a spring gets stuck etc. Despite all this, Inside the Spaceship is a crucial story. Since I only saw it for the first time about two years ago, I havent had cause to reassess it as I have the first two Doctor Who stories, and I've long been familiar with the story since the novelisation was published, but it still stood up well to a repeated viewing, especially in context. As I've noted previously, the two previous stories have presented us with a selfish Doctor, willing to use others and even kill to get his own way; they have also shown him having to deal with two new reluctant companions and their challenges of his decisions. Here we see the final stage of the DoctorÂs early development. When the TARDIS is on the verge of destruction, the Doctor is both paranoid and selfish  he assumes that Ian and Barbara have sabotaged his ship, even though they almost certainly wouldnt know how and tries to throw them off the ship regardless of what might be outside. He ignores their suggestions and ideas and continues to distrust them even before he suddenly comes to this conclusion, and seems to blame them partly because doing so offers the path of least resistance; it hides the fact that he doesnt fully understand his ship and allows him to avoid more frightening possibilities such as an alien invader. Despite his closeness with Susan, her defense of the teachers, or at least pleas not to throw them off the ship, go unheeded  he counters her assertion that they cant be responsible for the events in the TARDIS by patronizing her or brushing off her arguments with a wave of the hand. It is only when the truth of the matter starts to become clear that he realises his mistake, and I think it hits him a lot harder than most people realize; initially, as in the Cave of Skulls and on Skaro, fear makes companions of them all once again, the Doctor even asking Ian to face the end alongside him. The four of them work together in frenzy, desperately piecing together the clues, until they release the Fast Return switch and the central column starts its regular rise and fall. After this, the Doctor is forced to apologize and admit that he his wrong, and whilst Ian accepts this graciously, Barbara, who was instrumental in saving their lives, is less forgiving. Already, the Doctor has been forced to accept that his new companions have been instrumental in saving his life and SusanÂs, and he has had to admit to even less knowledge about the TARDIS than his inability to pilot it has already suggested, and I think that despite already having Susan with him, it is story in which he comes to really appreciate the company of others on his travels. But in addition to this, his obvious embarrassment and shame at his treatment of them in this story is brought out by Barbara, who forces him to make a proper apology the line as we learn about others, so we learn about ourselves I think signifies an acceptance of his less noble qualities and a desire to be rid of them. From this story on, the Doctor is increasingly willing to become involved, and most significantly, he increasingly endangers himself to fight evil. This is a result of the trials of the first three stories, and is one of his most enduring character traits a far cry from his attempt to kill Za or his casual willingness to let the Thals sort their own problems out until he needs their help to retrieve the fluid link.
Susan, who I have criticized when discussing the two previous stories, does well here the scene with the scissors is both disturbing and dramatic and is well-acted by Ford; she has never seemed so unearthly. Her paranoia is more unsettling than the Doctors, precisely because she has been so trusting of Ian and Barbara up until this point and it is interesting that she seems more sensitive to the TARDIS than he does at this point possibly part of the same theme developed further in The Keys of Marinus and The Sensorites. She is also generally surprisingly likeable (so perhaps I have, after all, reassessed this story) and is instrumental in cementing this first TARDIS crew together, as the natural link between her grandfather and her teachers (it is she, remember, who prompts the Doctor to apologize properly to Barbara, and he always seems more stung by her disapproval than that of others). Ian and Barbara also get important roles, especially Barbara who proves that she doesn't need Ian to solve a problem she is the first to realize that the TARDIS is trying to warn them of danger and she sticks to her argument even in the face of withering scorn from the Doctor.
The TARDIS of course is the final thing worthy of note  despite glimpses in The Dead Planet, it is here that we first get an idea of just how big it is and of course, that it is far more than just a machine. This idea will of course develop with the series, but seeing for it the first time it does make the old girl even more fantastical and much more than just a vehicle. It is also interesting seeing parts of the TARDIS later disposed of the food machine pretty much vanishes after this point, as does the fault locator. The console room itself looks better at this stage in the showÂs history than at any other, in terms of size, furniture and overall layout, beside which the versions to come in the colour era look positively tiny.
So overall, 'Inside the Spaceship exists simply to complete the development of the TARDIS crew from reluctant strangers into a group of friends with mutual respect for each other. It does it well and is claustrophobically directed, all of which add up to an overlooked but crucial story.
