I had bookmarked this a long time ago to read, but only just got to it now, and I really liked it.

The ending was an absolute glee moment, to find out exactly who Andrew was, and what Dean had done--on so many fronts! And I loved the line, "And you could've warned me that your wrath has freckles." The wrath of God. Gotta love it. Such a layer-y observation masquerading as an off-handed but rueful admission. Very very cool.
