Adrian renews an acquaintance, Dan is a reluctant booty call, and things aren't quite the way they were before. (Now with more surprise erogenous zones.)
or: anything that can go wrong in your tentative courtship of a miserable ginger vigilante, will. The first time Dan sees Rorschach without his mask, it doesn't go so hot.
"We went about fighting crime in very different ways, Dan, but I felt like we could have understood each other. You were always very genuine with your heroics. I admired that." His eyebrows gave a sardonic little lift on 'fighting crime', but otherwise he seemed as earnest as Dan had ever seen him. 'Earnest' unfortunately not precluding 'full of shit', in Adrian's particular instance. Merry Christmas! Have a fanonically-Jewish character and his probably-definitely-an-atheist vampire boyfriend bickering.
For the prompt of Adrian being a big nerd, him being a small nerd about something that isn't Egypt or Alexander for once. When Adrian Veidt is twelve years old, he discovers Homer's Iliad.
