Great episode! Probably one of the best ones this season.

Warning, Spoiler:
Called it! Knew Gillan was lying at the conventions. I actually got a little misty that final moment Matt Smith looks at Karen Gillan. They were both brand-new, thrown in the fire to keep Doctor Who going after the David Tennant/RTD era. And by god, they both did it better than anyone could have imagined. So, if this is Amy and Rory's goodbye, then I'm damn good with it. Kind of surprised Moffat wasn't the one to write this one, though.
