Snapshot 1 – DM is an idiot and offers to buy HP for more that the Malfoys is worth. HP is being sold, for whichever reason you want.
"Let us start the bidding on our final and most awaited round, Harry Potter."
A glasses-less Harry Potter in form-fitting clothing elegantly strolled onto the stage, face a blank mask and brilliant emerald eyes challenging the audience.
"Let us begin at one hundred million galleons. Do I have an offer?"
The offer was taken, and raised increasingly, in increments of ten million galleons.
… "One hundred and fifty." … "Three hundred." …
"Five hundred!" A voice rang out from the doorway. It seemed that Draco Malfoy had snuck his way into the room, uninvited and unnoticed in the furor. He had heard, earlier in the day, a conversation between his father and godfather. He had thus learned that Harry Potter would be up at auction. Thus, acting foolishly, he snuck in amidst the bidding, and bid five hundred galleons, not knows the true denomination. He had simply wished to humiliate his rival, not bankrupt his House. Nor did he truly understand, or even sense, his error at the moment.
"House Malfoy does not support this bid," Lord Lucius Malfoy proclaimed, voice ringing above the murmur. "House Malfoy will not pay for it, and furthermore I proclaim that Draco Malfoy is no longer a member of House Malfoy."
He had to do something to salvage his House, and Draco was never proper Lord material to begin with. He had also recently began to plan setting up his son, Harry, as the next Lord Malfoy, and thus was somewhat relieved to have the excuse to disown the air-brained ponce. He had brought it on himself, with such an outrageous offer.
"But father!"
"Silence! I am not your father, and never was! I hereby proclaim Draco No-Name, formerly Draco Malfoy, not a member of House Malfoy in any way, shape, or form. He will not be allowed to benefit in any way from House Malfoy, unless he provides a equal-valued service to one or more members of the House, pending Lord Malfoy's approval. So have I said, so may it be." And with that, Draco became Houseless, and nameless.
"Fa—" Draco No-Name was banished out the door by a furious Lord Malfoy. The door shut behind him, cutting off the word.
