Harry and I are bloody screwed...

Scarlet Williams, one fourth of the golden quartet. With parents who are both death eaters, she's evil to her house, Gryffindor. And being in Gryffindor means she's a traitor to the Slytherins. But, what happens if a vampire is loose at the Quittich world cup? And what happens if she and Harry are bitten? And what happens if two people take the spot of the fourth champion, a duo in place of where Harry had been in the real books? The definition of 'in this together' just got a new meaning.
