Check out my
character list and let me know what you think. My initial thoughts are:
+Molly Weasley - same age, same House. She's quiet as well, but more because she's withholding. She's an impossible mystery. She's intelligent, but she's known to slip away from class to smoke and spend her weekends partying. She's hedonistic but doesn't really ask for the attention. She enjoys physical intimacy but has never found the affectionate and doesn't think she wants it. She's cold but she also knows what is right. She's at Ilvermorny.
+Margo Richards - same age, same House. Margo is a lovable dunce. She's blonde and busty and that's probably all anyone thinks of her. But she's ridiculously loyal, occasionally insightful, and genuinely kind. She's not the smartest cookie but she's also admirably bold. She's also Molly's best friend. They're rarely seen apart. Mostly because Margo never leaves Molly's side. She's at Ilvermorny.
+Wendy Fudge - same age, Hufflepuff. Wendy is sunshine embodied. She's a traveller with a nostalgia for a life she's never had. She has three other siblings at Hogwarts and makes it her priority to take care of them. She's at Ilvermorny.
+Alice Longbottom - same age, Hufflepuff. Ace is helping kick start Potter's Army with Christian Zabini and is a bit of a handful. She's not at Ilvermorny.
There are more options on there, but those were the first ones to come to my mind.
