His explanation for this unusual behaviour was as follows:
"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, you have been warned!
As ever, The Gallifrey Times will aim not to spoil any of Series 10 for anyone and post warnings if there are spoilers in any articles. However, one thing's for sure, if there's a spoiler so big that Moffat doesn't want you to watch it, then something exciting must be about to happen.
