Margot's usually unshakeable, but when Malfoy's taunts hit a little too close to home she finds herself making a stupid bet. Usually doing impulsive, reckless things was more her brother's hat, but apparently she was overdue. She'd be more impressed with herself for thwarting the goblet of fire's age-line if she hadn't been picked by the damn thing. Eventual OC/Malfoy

People fear what they don't understand, or at the very least it makes them uncomfortable and Luna's often on the receiving end of that discomfort. Charlie has a soft heart for people who don't fit the mold and a hot temper for those who target them. Nevermind Charlie's determination to figure out all of Luna's quirks. She's always loved a good puzzle. Slow burn.

Margot may not look like either Lily or James but she prefers it that way, she'd rather command attention on her own terms, without preconceptions. It's no use being the centre of attention all the time when they'll always see you coming, and shocking the socks off of everyone is always a good time. Slow Draco/OC, but otherwise cannon.
