...now includes a brief snippet from one of the newly returned episodes of The Web of Fear when Clara falls into the Doctor's time stream, I notice.

Really? .. that's a great idea including the new stuff

Did they replace the clip of Patrick from the Five Doctors? I'm going to have to catch that on iplayer.

No, there was an extra close up of Troughton (which is possibly from The Enemy of the World) and a sepia tinted Yeti lowering its arm (from episode 5 of Web).

Is this a wind up?

I've still got a recording of the original broadcast, looks like they were already there. It's the sequence of the GI in the timeline rather than Clara, at around 31 minutes.

I smell bull excrement...

You're right! Damn, I thought I was on to something there...

Unless, of course, that shot of the yeti is from one of the newly returned episodes, and they sneaked it in months ago and we never noticed...

Yeah, the thought did occur, that would have been super cheeky. Even if they were the existing episodes, we might still wonder why they picked those clips at that point.

The shots were there in the original as well now that I look back. Love the idea that we all missed something potentially huge at the time haha. Of course they may have been from existing episodes.

It would have been too risky I guess. Some eagle eyed person would have spotted it in one of the many forums and it would have spread like wildfire.
