Doctors with Two Hearts
Well, first of all, there were complications with our regeneration, resulting in hyper activity, then we dropped into a healing coma. Rose took us to her mum's to recover, but while we were out cold, there was a do to with the Sycorax, who were trying to force Earth into surrender by using that ploy they do with controlling people with their blood? Anyway, we came to, fought their leader in a sword duel, where he cheated and sliced off our hand. But because we were so close to our regeneration, it grew back, and we defeated him, and sent the Sycorax scurrying.
