Alexander says she needs to be inducted into the A-Team! Because people with A names are awesome. She would fit right in! Right with the crazies! Which means she might want to be in on the horcrux plot coming up! Some of the DEs, the crazier ones, want to try making their own. She has Alexander's respect so that says a lot.
Daphne would know her too! They're about the same age and Slytherins! I can see them being friendly but not super close. Yet they run in the same circles so yes!
Ginny rather despises her but big surprise there. Fleur doesn't like her either but there is a lot of conflict potential there.
