Sal is what you would call a calming presence. He's possesses a strange talent for the arts and is the voice of reason among the chaos of the others. He balances the chaos by providing a second opinion in a less hostile light. He's very agreeable and is great for emotional support. He's also developed a taste for human narcotics and other drugs to further enhance his own presence and even practically dominate Silva. He's the most trusted to be in charge to suppress the others when Silva himself can't handle the stress.
