Detlef makes it sound like he confessed to having the Vice, but Dain wouldn't be at all surprised if the other man stumbled on the secret the same way Lorne and Dain both did just now. Still, it's good to know the couple are happy, and not just because the audible murmuring through the cracked doorway had put Dain immediately on edge.

He drops his face into his hand, laughing softly to himself. Detlef confessed because he didn't think it was fair to be in a relationship with someone who didn't know he had the Vice. This -- this is the sort of world Dain wants to live in, which clashes badly with the self-preservation instinct he definitely has, and it's funny, and it's definitely not funny, and it may or may not be worrying to see a Shepherd laughing like this, but it feels necessary to mark the absurdity somehow. Either way, it doesn't look like words are forthcoming.
