If 10 already met 11 then he would know 2 things that he wondered after he regenerated
1 he should have know he wasn't ginger without looking
2 he should have known he wasn't a girl

You're right. They should scrap the entire plot of the fiftieth anniversary. I just hope Moffat has read your post and realises why the episode won't work.

I agree it's an outrage it's worse than the changing of the leaf

because of course there is no possibility whatsoever that this sort of thing may be considered when writing the script.

What? First of all, we haven't even seen the 50th so we have no idea what Ten will learn about Matt's Doctor. For all we know, Ten could think Eleven is a total stranger who needs his help. And even if he learns it's a future version, he might not ask which future version.

Just saying bad continuity

how can you even say that without knowing the plot of the 50th? It might wind up being that Ten and Eleven never even appear on screen together, or Ten may be left with no recollection of the events of the episode. Just two of the hundreds of possible ways to address the entirely trivial issue you raise.

So not only are we slagging off current episodes unrelentingly but we are also going to start criticizing episodes that haven't even finished filming yet? What a great bunch of fans DW is lucky to have.

You've seen the script, then?

Like a lot of people on here have, seemingly. And none of them like it.

I'm spoofing the leaf thread

In the previous anniversary multi-Doctor episodes it was implied that the Time Lords removed the memories of the relevant events from all relevant characters . Of course the Time Lords are no longer around, but there are any number of other ways that relevant memories can be removed.

Well I wake up each morning and say "STILL ginger!". Go Gingers!

Timey whimey.

When we saw 10, that was in a version of timeline when he hadn't met 11. When they meet, possibly by 11 going back to change the past, that's not a fixed point. So the future him changes to one who has known 11, and so at the point of his regeneration he would then know those things and wouldn't actually say them.

Plus, of course, when 10 and 11 meet who is to say that 10 knows that's the very next him and not just another him further down the line?

Could the 10 possibly be Rose's 10. Half doctor one?

Hopefully because I would love to see current Rose react to 11

If so then that would explain about the ginger thing
