I like this very much. I think it stays pristinely pure to one of the show's central themes -- that of Sex as Revelation. I thought the ending flowed naturally, served as the climax of the piece -- Ethan has been gradually making "discoveries" throughout, or at least admitting things to himself, and the rapid fire bam-bam-bam of the closing paragraphs just reinforces the discovery-and-sex metaphor.

Very nicely doe! You made me enjoy "Ethan fic" ;)
