Sorry to divert this thread a little but this has been bugging me for some time.
The weirdest thing about the Angels comes from the sentence, "That which holds the image of an Angel
becomes itself an Angel
". It was alright when the image was on the television, but Moffat went and include Amy's eyes. So what made Amy's eyes so special? Why is it no one else who saw an Angel got controlled by the Angels? Why is the Angel is only in control when Amy open her eyes and is presumably being observed? Shouldn't it be the opposite - that the Angel can only control Amy when she close her eyes because no one is observing it?
While I'm at it, the Angels fell into the crack. And we now know Gallifrey and the Timelords are in the crack too. Does it mean there are Angels on Gallifrey?
