Really thinking about it.
That could so work. I think the power issues are what really caught my attention (because it's sure not how they'd physically look together!). Moody'd so be the top, and imagine how he'd make Draco pay for even being related to DEs.
(Note to non-hp_dungeons folk: In the RPG, Draco is years older. No worries on the whole age thing, at least in this post.)
