Anyone who's seen Sliding Doors is familiar with the premise. A seemingly insignificant decision, maybe even not a decision at all, but a missed opportunity - something small, something you'd never think of twice - and yet, it's a turning point. A point from which a startlingly different life path branches, and the consequences could be monumental.
So the case is with Donna Noble, who is thrust back in time by a dodgy fortune teller and a "time beetle" (the less said about the big silly plastic bug, the better); to a literal crossroads, where she turns right, instead of left, as she'd originally done. That decision takes her away from her potential temp job at H.C. Clements, away from Lance, away from the Racnoss... and away from the Doctor.
And things only go downhill from there.
It's a fascinating concept, really. We all have probably asked ourselves "What if?" "What if I'd gone on to get my Master's degree? "What if I'd asked out my high school crush?" "What if I'd taken that trip?" And it all comes down to "How would my life have been different?" Thing is, sometimes it's the little "What if?"s that could be the most important pivot points of all. But either way, our lifelines, our potential stories, can branch out in myriad and wildly different ways – and in this episode, we get to see what Donna's life was like without the Doctor. In fact, we get to see an entire world – Universe – without the Doctor.
What happens if the Doctor dies?
According to the events of "Turn Left", plenty of bad things. How bad? To quote the Doctor "Think how bad things could possibly be, then add another suitcase of Bad". London devastated, all of southern England irradiated, tens of millions of deaths in the US, refugee camps, concentration camps, and then even the stars themselves start going out...
So yes. Bad. Very bad. And suddenly Donna Noble, who thinks she's no one special at all, becomes the most important woman in all the world.
Also, Rose Tyler is back, and that's made of awesome any way you look at it. Rose spends her time being mysterious and steering Donna away from certain death, while trying to convince her that she's the one who can change the world. And then, ironically, sending Donna to her death (or "death", depending on how you look at it) with a very Doctor-like "I'm sorry". But not before giving her a message for her other self to send to the man himself. Two words. Just two.
BAD WOLF.
And if you think the hairs on my neck didn't stand up and goosebumps pop up all over me when Donna delivered that message, and the Doctor went tearing out into the marketplace, back to the TARDIS, with the words everywhere around him and the music pounding along completely nuts in the background, then you don't know me very well.
That was a damn exciting scene, right there.
A sadder scene? The dying TARDIS. I'll have none of that, thank you very much. Is it sad that I was brought to tears at that bit?
Much like the moment Donna decided to sacrifice herself. Catherine Tate really sold that scene, much like she did every single moment she was on screen this episode. She was phenomenal in this. She carried the episode, and she was phenomenal.
Billie Piper, too, was wonderful. Talk about a triumphant return. She played Rose a little harder, edgier, sadder... but still with a compassionate heart. She also had a great line delivery with "great hair... some really great hair".
David Tennant. What can I say? When is he not brilliant Though he wasn't in this for long, that scene at the end more than makes up for it. The look on his face, the way it slowly changes as he realizes just who Donna is talking about... it's gorgeous.
I also love Rose telling Donna she was already brilliant, the Doctor simply showed her that truth. And that he does that to everyone he touches. Because: yes. That's one of my very favorite recurring themes of this show.
Well, that and Bad Wolf. Which is where we leave off, with the timeline set right and the Doctor alive and well and those two words emblazoned on every surface, even on the TARDIS herself. Heralding the "end of the Universe", if you ask the Doctor, standing there in a console room bathed in red light and backed by the sound of the Cloister Bell.
But we know better, don't we? It means Rose is coming back and we'll all get a very happy ending. Right?
Right?
Next week. The Earth gets stolen. And: Companionpalooza!
