::snicker:: I do so love what Lucius managed to do to himself; I'm certain Narcissa and Tom will express their displeasure to him intensely and at length. The sequel should be fascinating.
For those who don't know, TTH is "Twisting the Hellmouth" and may be found at http://www.tthfanfic.org . There are some other great BtVS/HP crossovers there, for after you finish what's there of the sequel, and I can especially recommend Greywizard's work.
