A few points from our commenters, too. Guysmiley asked “is noone else bothered by the fact that the doctor has effectively spent the entire episode trying to show that the flesh copies of people are people in their own right and especially that his own ganger is every bit as good as himself, only to reveal at the end to Amy that she too is a ganger, and that he’s known for some time that she’s a ganger, whom he then effectively kills? Isn’t that actually cruel?”

Salady, meanwhile, questions just when the copy of Amy was made, because they argue it must be before she was pregnant. Ganger Amy has had no bump, after all, while real Amy is ready to give birth. That, or The Silence impregnated one somehow, and sent the copy they’d taken back?

Gherkinsarecool throws in the fact that Amy’s house that we see in The Eleventh Hour has a mysterious third storey to it (there’s echoes of The Lodger about that, too). So, have we ever had the real Amy, or has she been some kind of trap all along? And DCDJ18 wants to know why Rory hasn’t noticed that his previously fashion-conscious wife has been wearing the same clothes for weeks. Perhaps there’s a reason for that, and there might be a slight hint in the trailer for A Good Man Goes To War.

BlameSimon (er, cheers!) wonders if Amy is actually giving birth to twins (the dialogue we hear is “one’s on its way”, which might hint at two little Ponds), while Chiddler points out that “the technology used to keep Amy connected to her duplicate of the TARDIS is incredible – it connects across time (1960s USA, 18th century pirates, 22nd century factory), space (the House – an asteroid outside the freaking universe!) and into the TARDIS while its travelling. That’s seriously advanced, whoever is behind it is very dangerous indeed!”
