1. A bit of utopian what-iffery about education policy at CiF.
2. There's one thing I still don't understand. If that watch contained all the essential nuts and bolts of the Doctor's personality, and represented the only chance that he might get his real self back, might it not have been a sensible idea to entrust it to Martha, who knew how important it was, rather than leaving it with the oblivious 'John Smith', who just bunged it on the mantelpiece and didn't even notice it had been swiped by the blond kid? Or am I missing something?
