Iris and Drusilla would know each other really well! She's also a Senior, though she's in Coppertale, but she was also a Gryffindor! So they shared a dorm! She's also a member of the Outdoor Exploration. She's the daughter of the current Minister of Magic, Kingsley Shacklebolt. So she knows all about having people recognize her by family. I think they could get along really well! This is Iris first year at Gooseberry, but she's happy to know someone really well from Hogwarts.
