The party was already well underway when Severus Snape stalked into Malfoy Manor wearing the usual black that drove the fangirls crazy. Lucius, however, answered the door wearing a large robe that was obviously meant to hide something. Severus was just about to ask what he had on underneath when Lucius whipped it off. He looked something like a horrible dream. Words could not express the terror Severus felt.
"Well, what do you think?" Lucius asked, walking away to get a glass of strong liquor he had poured earlier. He drank in big gulps; as if he knew what he would be facing that night.
Severus didn't answer. He just walked over to Lucius, grabbed the glass from his hand and finished it in one gulp. He stood there for a few minutes.
Severus finally spoke. "I think we should get more of that," referring to the whiskey he had just downed. Lucius handed him the whole bottle.
Needless to say, this went on for a while longer, until Lucius declared that that was enough for right then, or they would run out for the rest of the night.
"I think we should go and join the others. We'll be missed if we stay here any longer," He walked towards a set of double doors to his left, motioning for Severus to follow.
(A/N: This is where you use your imagination: just imagine the most terrible costume ever conceived, then smother it in glitter. That's what Lucius was wearing. I had other plans for the description of his outfit, but I'll save that for somewhere that will let me post HTML...)
