Somehow, the Doctor always seems to gravitate back to Earth; he often wonders why he’s so drawn to the planet and her people. Maybe it’s because humans seem to need his help more often than other races; after all, aliens do target them a lot.
So he’s back here yet again, and so are the Autons, causing trouble as usual. This time a young shop assistant has been caught up in their schemes. After so long alone, it feels good to have someone running beside him once more.
Maybe it’s time to make a fresh start, with a new companion.
