On one end of the spectrum, there’s that run of Doctor Who stories in 2013 which is all about the mystery of Clara, the mystery of Clara, the mystery of Clara. On this other end in 1983, you’ve got this seventeenish year-old alien who was hanging out in a posh private school and making secret murder contracts with immortal evildoers and practically nothing whatever was mentioned about it. I just can’t help but feel there’s a comfortable medium somewhere between them.
As annoying as it got in the spring of 2013 having every single story revolving around the Doctor investigating what his companion is up to and who she really is, it was still preferable to the cone of silence that was dumped on Turlough. This could have been so interesting. There are whacking great chunks of “Terminus” where Tegan and Turlough literally have nothing to do because the plot is happening elsewhere, but instead of writing some dialogue about this new character, all they say is “we’ve got to get out of here.” All of “Terminus” was a missed opportunity, but I’ll go to my grave thinking they could have improved things by having the two just sidelined and waiting and talking. “So where are you from, and what were you doing on Earth?” Even if Turlough didn’t want to answer these questions – I suspect that nobody had really bothered at this point to figure them out yet – why wasn’t the incredibly inquisitive Tegan asking them?
There are a few scenes in “Enlightenment” where Turlough does seem to act like a cowardly kid around seventeen years old. Usually, he’s not depicted that way. He’s a nebulous early-twentysomething in the hands of the scriptwriters, and just as every subsequent adventure is going to forget that this one ends with Turlough asking the Doctor to take him back to his home planet, every subsequent adventure is going to forget that the character is a teenager.
I shouldn’t complain. The program is just about to forget a character entirely. You want to talk about slapdash…
Fans sometimes debate whether the Doctor knew that Turlough was in league with the Black Guardian, and whether the Doctor had the right to put Tegan and Nyssa in such danger by bringing him on board without telling them his suspicions. I kind of like the friction between the Doctor and Turlough, and at least it gave Davison, who was very, very frustrated by the experience of making the show, something different to do.
I think the problem is that “Enlightenment” doesn’t have a payoff. We can guess that the Doctor knew the Black Guardian was behind this from the beginning and had taken lots of steps that we didn’t see to ensure his enemy would lose. I’ll find a thing or ten to complain about Steven Moffat’s six seasons when we get there, but credit where it could be due: Moffat would have made the end of “Enlightenment” completely spectacular, and Davison could have played the hell out of a tables-turning scene where the Doctor reveals that he was steps ahead of his enemy the whole time.
Instead, the Doctor just stands there. It’s not an impressive ending.
