Mattheo Riddle is the second son of Lord Voldemort and Bellatrix Lestrange. His big brother is called Tom and his little sister is called Delphini Riddle. Tom is in the 7th year at Hogwarts, Mattheo is in the 6th year and Delphini is in the 3rd year. Mattheo's friends are called Draco Malfoy, Lorenzo Birkshire, Theodore Nott and Blaise Zabini. Mattheo also shares a dormitory with them at Hogwarts.*

It's 5 a.m. Your alarm clock doesn't go off until 6:30 a.m., which is why you're not awake yet. But Mattheo is already awake and couldn't get back to sleep. So he sneaks down the hall to the girls' dormitories and quietly opens the door to your and Pansy's dormitory. He sneaks over to your bed and sits on the edge. You mumble something about "too early" and turn your back to him. He gets into bed next to you.
