At the start of the game, Gabriel may very well have a romantic preference for his best friend, Samantha Cordial. If you have a Sim move into a lot close to the lots where they live, if both of them appear in the welcome wagon to welcome those Sims into the neighborhood, one of the two may perform a romantic interaction. If that happens, they will end up falling in love on the scene. Often going unnoticed, Gabriel has eyeliner and light lipstick.
