8. Paranoia
Just look at the face in this picture. It is the moment that The Doctor locks Ian Chesterton and Barbara Wright in the TARDIS. He's clearly mad and I rest my case. That's not enough and you would like a more coherent rationale for the argument? Think back to that first episode and you will spot one straight away. He locked them in the TARDIS, because if they were to get away they would 'reveal his secret'. Excuse me, but surely this is the reasoning of an ultra paranoid barmpot? What secret was that? There is a bloke that lives with a young girl in a police box standing in a junkyard that's bigger on the inside than it is on the outside? Really, if two perfectly sane looking teachers came into the school next day with that sort of story they would be laughed out of the staff room. Especially when, having left Earth, there was no further trace of said police box anywhere to be found. And of course they did not actually know anything about The Doctor or his granddaughter by then, so there was precious little else to 'reveal' in any case. The only remaining 'revelation' would have been some footnote story or other in the Fortean Times some forty years later after the magazine had stumbled across two mad old, retired teachers. If you think that that moment was just a one-off aberration then follow the rest of the first series. He is continually suspicious of Chesterton all through. Later on in life The Doctor keeps doing things with people's lives in very mysterious ways too, often justifying himself with timey-wimey flibber-flabber. If you ask me he's just deeply suspicious of everyone around him!
