Ok she DEF. has to be friends with Rolf for oh so many reasons. Coulda have met abroad (he's been all around) and is friends with Jackson so he coulda gotten to know her more recently through that. Either is awesome and he's excited for another magizoologist around!
Other than him...I don't think the rest of mine will know her. But Sam thinks she sounds cool. Trevor is Trevor so she's prolly happy not knowing him. And Maeve is just indifferent.
