I find this very consistent with my pet theory that it will be part of an "alternative Amy" story arc that might - or might not - get resolved in the Amy's Choice part.
Imho this is not the "real" Amy or timeline as it should have been if the Doctor HAD actually arrived back with little Amelia 5 minutes after sorting the TARDIS out. The whole timeline seems wrong, Amy has been turning into something she probably shouldn't be (think Kissogram

), it would explain her "off" comments that have alienated myself and seemingly others in previous episodes.
I am waiting for the Doctor to get eventually back to the "right" back to little Amelia part
So I am not getting overly nervous yet.
But then, this is just my personal theory on the unfolding story arc
