Matthew has a close relationship with his father. Being the curious inventor Henry was, he had a tendency of endangering himself with his experiments. Matthew took it upon himself to look after him.
Matthew unwillingly attended the Shadowhunter Academy in 1899, where he became considerably popular among the students. Wanting instead to return home to look after his eccentric father, Matthew took every opportunity to discredit himself to get expelled—an unlikely idea given his mother's position as Consul. At the Academy, he was friends mostly with Christopher and Thomas Lightwood and had an initially complicated relationship with James. One morning, he and James finally had a conversation about their situation and realized that they were being rude to each other for no reason. The pair since became very close friends, despite the revelation that James had magic.
After setting up an explosion with Christopher that would surely get him expelled, Matthew left with Will and James to the London Institute, something the Herondales agreed to after Matthew surprisingly proclaimed his desire to become James' parabatai.
Matthew is said to be very sensitive, though also always delightful, open-hearted, sociable, and funny. He is also rather indolent, is flamboyant, and is a party boy, though he listens to his parabatai, James, who manages to make him attend to his studies and keeps him out of trouble. He is also a fan of Oscar Wilde and the aesthetic movement.
