A Convenient Marriage

CHALLENGE: Severus Snape Fuh-Q-Fest Bonus Challenge: Sirius must ask/beg Snape to marry (and consummate the marriage) with Harry. Also, Casey issued this challenge: "It's after the war. The good side has won but Lucius has managed to wiggle out of it, though his finances are now less than they were. To bring back prestige and money, he invokes an old law that says a house could attach itself to another by marriage, with little recourse to the other house. Lucius obviously chooses Harry. The only hope Harry has is that it is allowed for another witch or wizard to step up and duel Lucius for theright to marry HP (marriage must be consummated with Veritaserum given the next morning for proof). Snape is the only one who qualifies."
