Did we ever solve the Q pics of London? Someone connected the dots on a map of where they were taken and it reminded me of this DM story regarding the Royal 'Carriage-cade' route.
My thoughts were that the photos were used for scouting locations for a FF during the Royal wedding. Possibly sacrificing the multi-breed TV star in the process.
Now that THEY know that WE know, I wonder if Harry will actually marry they little lamb?
