During last night's press screening of the Doctor Who Series 10 opening episode 'The Pilot', Steven Moffat teased an "enormous spoiler" in the trailer that precedes it.
Moffat apparently encouraged the audience to close their eyes at a certain point during the Episode Two trailer;
"This is just a public warning... some people hate spoilers and some people love spoilers; and everybody hates me whatever way they think about it. So this is my last attempt in this role to avoid hatred.
At the end of the episode there will be yet another awesome trailer for Doctor Who. At the very end of the trailer there is, frankly, an enormous spoiler, a spoiler that may actually melt your brains. But I promise you, you'd be better off not knowing because - awesome though it will be here - it will be even more awesome in a few weeks' time. So we're gonna give you the option, in our frankly camp and ridiculous way.
There will come up a warning and then there will be a countdown to the spoiler, and then there will be a warning to 'blink now'. If at that point you close your eyes and wait until you hear the cliffhanger noise, you will have a better experience in a few weeks’ time."
So what could this spoiler be?
Well, as the loyal readers among you will know, DWO is a spoiler-free site, but that can't get in the way of a gentle bit of speculation. Now we could be completely way off with this, but we believe the spoiler *may* be centred around The Doctor's granddaughter, Susan [Foreman]... and here's why:
Let's cast our minds back to yesterday, when the Radio Times released an image featuring 13 clues from Series 10. One of the clues (No.3) was a book that Pearl Mackie was holding - a book that anyone who is familiar with the Penguin Classics will know as 'Northanger Abbey'.
What a lot of people don't know is that Jane Austen (the author of the book) originally titled it 'Susan'. Based on the prominent placement in the image, as well as the brief shot of a photo of Susan in a recent clip from the episode, our money is on Susan being the big spoiler.
We could, as we say, be completely wrong, but it's a very exciting prospect if true! There are other possibilities of what the spoiler could be, including a regeneration, another Doctor or even something connected with the Time Lords...
We'd love to hear what you think the spoiler is. Do you agree with us? Do you have another theory? Let us know in the comments box below or in the DWO Forums, by clicking the 'Discuss' button.
+ Series 10 of Doctor Who airs from Saturday 15th April 2017.
