Alexander arrives in Tree Hill, hired by Victoria to help Brooke out with the "Clothes 4 Bros" men's fashion line. Alexander took an interest in Brooke, as she was still upset over her belief that Julian was falling for Alex. Despite this, he had been secretly dating Victoria while also hooking up with Alex for sex. Alexander and Victoria's relationship was outed at the grand opening of Quinn James's art gallery, which caused a rift between Brooke and Alexander and Victoria. Brooke ultimately put aside her differences, allowing Alexander to take over the Clothes 4 Bros line and run it from New York alongside Victoria.
Alexander had brief relationships with both Victoria Davis and Alex Dupre. He also showed quite an interest in Brooke Davis, always calling her 'beauty' and 'beautiful'. In Haley's 80's dance party, he also stated, "Brooke Davis, stunning in any decade."
