Meaghan; I'm sure Aurora would be at least aware of her because of Quidditch! She would definitely be polite towards her, so I imagine they could be acquaintances!
Daisy; Well they have a love for art so I definitely think they could have several conversations on that! She'd be pleasant towards Daisy!
Barnabus; Yay study groups! She's all for that!
Emma; Aurora might be a little put off from Emma but she would still be nice.
