Ah, I have Sirius Black, who is a sixth year Gryffindor and likely to know her. I offer him up as a friend/acquaintance/past random snog/etc. Then there's Abner Bloom, fifth year Gryffindor, who would probably be terrified of her and stay away from her with a passion and a fear of his life, or some such thing, because he is generally terrified of women and rowdy women are worse.

Other than that, I have no clue. But all my characters are up for plottage, interaction, etc. (the others being Audrey Clavell, fifth year Ravenclaw, Alannah Morgan, sixth year Slytherin, Luann Browning, muggle studies professor). So PM me if you're interested and all. ^^
