Sweet and hot! This is a great pairing, and I like how you show the tension and secrecy they are both constantly surrounded by in their work for the Order. I like the Moody, as an old friend of Dumbledore's, knows that the Headmaster's plans get a little too intricate and trap other people in them - like Snape. I also like the ending, although it is very sad! I imagine that Alastor Moody would always have known a lot more about what was up than he revealed. So the way you have him refusing Obliviation says so much about him - a tough old guy like Moody must have kept a lot of secrets in his time.
