Ah... that depends entirely on *how* Harry and Lucius meet :). In the war, Harry will perhaps tender a very small little soft spot for Lucius. Should Lucius get the upper hand, though... he'll want to assert his dominance, and play with Harry the way he wants to ;). Although he, too, would have that tiny soft spot and not go cruelly far. I think they both ended up with a sort of respect, almost affection for the other - not a blind spot, but enough to stop them from outright seeking each other out in battle (at least not with intent to kill).

I'd be dead curious to see you do Snape/Ron! *giggles* I'm sort of writing a bit of it (mixed up with Ron/Peter and tons of other pairings), although that silly thing went on the backburner in favour of triatha_ron. ;)
