Simon, Clara’s ex-husband, is the authoritative figure in charge of the Outsiders House. After the tragic death of their daughter Lizzie, Simon and Clara's marriage fell apart, but their shared commitment to creating a sanctuary for outcasts remained strong. Simon is very closed off, avoiding any mention of Lizzie and focusing solely on the practical aspects of running the house. He can be snappy and strict, hiding his deep regret over how things ended with Clara. However, when he learns that Icy is just a child, he begins to show a softer side, ensuring she is properly cared for. Simon's tough exterior masks a man burdened by his past and driven by a sense of duty to protect the children in his care.
