Got the looks in the family, aside from being three minutes older than Alecto
Was Seeker for Slytherin, and thinks Hooch ought to let him coach, seeing as how everything's gone downhill since he graduated.
Once took Draco Malfoy aside and threatened to perform an anatomically impossible act on him if he should upset Pansy, his little princess
Calls his sisters by their baby names in private. Any else who called Alecto 'Allie' would find himself missing a body part or eight shortly after. When Amycus does it, she smiles.
Has the creepy sense that Millicent Bulstrode is flirting with him. He doesn't realize she's got terrible allergies, and the looks he's taken as adolescent passion are an attempt not to sneeze.
Has a singing voice so sweet it makes people cry. She can sometimes be talked into singing at the tamer revels.
