It's not so much that it's a crossover; it's that it felt more Disco than DW to me. But you've convinced me, so it's posted to Teaspoon now. (And thank you, I'm glad you liked it!)

I hadn't noticed that AO3 tic, btw. It looks like something about use of the old-skool <center> tag throws off its HTML generator enough that it adds a blank paragraph above the centered text and then doesn't bother adding a <p> tag to the paragraph that follows it. AO3, man ¯\_(ツ)_/¯
