Ex-Slytherin, current socialite, and somewhat the black sheep of the Davis family. Most people will know her as that really quiet, aloof Slytherin who didn't seem to talk much about anything beyond fashion or boys. This is pretty much all an act because it's how her parents expected her to act. Most Slytherins are even pretty clueless about the fact that she's intelligent and somewhat rebellious underneath her perfect little princess exterior.
PLOT? Pansy and Draco definitely, Astoria maybe? Depends on how likely she was to hang about her older sister. They'll at least be acquaintances.
