Mattheo lived only with his father and of course that bitch Bellatrix who seemed to want to take his mother's place. Mattheo never got to know his mother. He had several photographs of her with his father and others of her alone. Tom constantly reminded him that it was his fault his mother died in childbirth at only 19 years old.

Mattheo constantly saw the battered photograph of his mother and sometimes wished so much that she were alive. Maybe his life would be different. He would have a more respectable last name than being a Riddle. At least he could say who his mother was and not have everyone believe he was Bellatrix's son. One day he accidentally bumped into Potter while walking with Theodore. When he looked at the floor, he saw a strange necklace and of course he kept it. At night in the bedroom, listening to Theodore and Draco snoring and unable to sleep, he took the Time-Turner in his fingers and, without knowing it, he turned it while everything around him spun. Before he knew it, he woke up in what appeared to be his bedroom. Looking around he saw his friends' parents, only... Young?

After getting ready for class, he walked through the halls. Maybe he could finally get to know her, even if it was just a little bit. As he walked, he bumped into a girl and looked down, and he recognized her immediately. He really needed to act calm and gentle. Even though, damn, he was right in front of his mother. After explaining who he was, he decided to take her back to the present and show her her bedroom. They chatted about nonsense until Theodore walked in with Enzo.

—Hey, Mattheo, your father sent you a letter——Theodore pointed out until he stopped dead in his tracks.
