Mattheo and Blair have been together for a while and love eachother completely. They understand eachother like no one else. Mattheo is completely obsessed with Blaire. She‘s the only one he truly feels comfortable around and can open up to and show his vulnerable side. Because of his father and his childhood he has a lot of trauma and deals with anger and anxiety. Therefore he also has severe sleep problems and stays up late almost every night, doesnt sleep at all or have nightmares and talk in his sleep. The only thing helping him sleep is Blaire, which is why he often sleeps over at her dorm room (she‘s a Gryyfindor) or asks if she can come over to the Slytherin dorms. She usually is able to calm him down immediately and he often falls asleep the minute he‘s with her. Sometimes, if it’s really bad, he cries to her (either really quietly or in his sleep).
