OK so whats the story about Amy not knowing about Dalek's?
Seems to be something very funny going on with and around her.

and why is "the crack" following DW and amy around then???

OOOOOOOOOOOOOOHHHHHHHHHH

The New Daleks must have be will changes the future of history so that the events that Amy doesn't remember have will been not will happened.

Douglas Adams was right: the main problem with time travel is not meeting yourself, but grammar.

I don't think she missed the Daleks, I think it's more complex than that...

Perhaps she just had a Donna Noble moment and was scuba diving or something ?

I agree, she might have been lying to the Doctor when he asked her, for whatever reason.

Nah, I think the point is that she may not have seen them but she should, after the events of TSE at least be aware of the concept of them....

She missed them because she was too busy staring at her crack?

I wonder if this fits into the decimated Earth of 1963 that we see in the computer game.,,,

Perhaps she missed them because she was in a coma.

Do we actually know what time the Doctor met her again in "Eleventh Hour"? May have been before the events of "The Stolen Earth"...

I don't think The Doctor would make a mistake like that, I think the point is something has messed with Amy's memory/manipulated time lines or something.

perhaps leadworth was kept in some sort of bubble as a result of the tardis or something - other events in the real world didnt occur there due to the crack in the wall - when the dr sealed it he also sealed in leadworth - puttn git out of sync with the rest of the world - in its own time thing - similar to how the timelords and daleks etc survived

this was odd remember way back in The Next Doctor, the Doctor said it was odd that nobody remembered the giant cyberman thing too maybe the two are linked

Well I was thinking before he said it that Amy should know all about the Daleks - maybe Moffat has had to come up with something to restore the human race to its lack of knowledge about aliens, otherwise future plot lines would be pretty difficult.

I think that the cracks in time, the 1990 label on rory's hospital badge, the lack of dalek knowledge etc are pointing to the series arc. I think the moff is pressing the reset button on RTD's tenure. It's my feeling that the doctor has been shifted into a parallel universe where the events of the past 5 years of doctor who haven't happened.

Probably the Tardis being late all the time may relate to this as well?

Assuming that TEH happened mostly in 2008, the Daleks moving the Earth happened after the bulk of that episode, but before he came back for Amy. She should've known about the Daleks. Either time has been changed (in which case, the clone Doctor has been erased from existence, as the Daleks weren't there to trigger the faux regeneration which created him!) or she's from a parallel universe (but not the same one Rose is in).

I think it's because at the end of the series Amy and the Doctor become crack addicts.

It's probably because of the crack or "the big reset button" that's appeared in the 3 episodes so far.

The crack in time is probably affecting time itself, allowing Steven Moffat to push the reset button to bring back Daleks, Cybermen, The Master and probably a way to explain The Doctor's past regenerations being reset for the future.

I'm wondering if things can bleed out of/be sucked out of the crack?

Surly there couldn't be a "big reset button" erasing the memories of the past 5 years events as in TWM Adelaide Brooke tells a story which she remembers from that time, so timey stuff means they cant change the future, can they?

If Rose is sucked back I'll switch off.

I wouldn't mind if 10.5 is sucked back on his own. It could be an interesting reunion (of sorts) between him and the Eleventh Doctor.

Depends what universe they're in.
