Who kidnapped Mrs Hudson????
You know, I am the first to admit that I tend to notice the wierdest shit, but this one takes the biscuit.
In the graveyard scene, as Mrs Hudson walks away, she pauses for a moment, turns to look back at John, and then as she turns away again, a mysterious hand shoots out and drags her behind a grave stone.
as ian hallard said
