Sal was an adventurous teenager. He seemed resourceful and had a knack for staying calm in stressful situations, as seen in his interactions with ghosts. He seemed friendly and polite, despite the rude or frightened responses he might get from people reacting to his prosthesis, and was frankly affectionate with his friends. Sal often offered to listen or say a kind word to others, even those who were unfriendly towards him.
