Leo's family and Hemia's would at least know of each other. Hermia is very, very French (Dad's a French Ministry Ambassador and the Bonnacord's are an old pure family). She takes looking after younger students very seriously and would love to help him get his footing (@Tommy Tupper, too). She's also French Club president and will always be happy to forgo English when given the chance.

Anne Moony is a second-year and I promise she will find Leo insufferable, at best.
