Out of sequence I can buy. Reverse order may not work. But I'm sure that whatever timey-wimey-ness Moffat has in store for next week, I'll wind up being surprised by it, even if everyone else saw it coming a mile away.
How does that square with the fact that the Doctor didn't recognise Rory's dad two episodes ago, but they're well known to each other this episode?
It doesn't. But it does square with the fact that Rory left his phone charger in Henry VIII's bathroom last week, and was under Henry's bed this week; and that Amy said she was a queen in Dinosaurs and accidentally said "yes" to Henry VIII's wedding vows this week.
And I'm told that the ads you're getting in the US say "every story has a beginning, a middle, and an end - but not necessarily in that order."
Another plausible explanation I've seen for the phone charger bit is that A Town Called Mercy actually takes place while they're off travelling during the course of this episode, shortly after the Zygon-invaded Savoy and Henry VIII's bedroom.
