writing moment on subway

I just had an amusing moment on the subway, where an idea for my Harry Potter story (the one I last updated in roughly the Crimean era) popped into my head, necessitating a frantic scrabble for loose paper in my pockets, occasioning some bemused glances from my fellow riders. The whole thing is starting to turn into a fucked-up PR war between Scrimgeour and Voldemort for the hearts and minds of Wizarding Great Britain- fun times :P
