This is a very interesting take on these characters; it's surprisingly tender, considering they're both depicted as rather starchy (to say the least!) in the books. And wartime really does make people forget themselves and go off and do crazy stuff they wouldn't ordinarily (to the eternal thanks of fanfic writers everywhere :D).
Thanks for this! It's intriguing (always a good thing in my books) and certainly makes me look at the possibilities of this ship in a whole new light.
