HI BRIT!!! it's Lyss and I have two here! I actually stole Addy Foster-Hayes aka this one from Olympics because I really missed Libby so that's basically who this is. She is from Virginia, is an Azurcrest junior, and is very kind but very flighty, and thank god she's good at Potions or she would've failed out. BUT she is best friends with Ramon's sister so she will definitely know him and probably at least try to treat him like a surrogate baby brother, I am so sorry already. She would probably be a little wary of Antonia because she breaks a lot of rules but she would be nice mostly!
And then I have Leonardo Fiori over at challenge. He is an Ebonhide senior and Beater and captain of his team. He is also trying to be an Auror and is going to change into a snapping turtle Animagus soon. He is very busy and ridiculously (dangerously?) competitive, but he really isn't taking himself as seriously as he acts. Mostly. He again would know Ramon and definitely have his Eye On Him. He doesn't underestimate you baby sophomores.
He's also in the same house as Antonia and would for sure know her too! He tries to keep on good terms with cheer people so they're not tempted to stop cheering Quidditch...
