Sylvester Stallone reveals he found out his 36-year-old son Sage died in a cold, 10-second phone call from a stepfather he had never even met and says the guilt still haunts him. Sylvester Stallone: "You have so many episodes of guilt like, what could I have done? Should I have been there? I'll never forget how cold it was. My mother's new husband, whom I had never met, was a doctor. I get a phone call on Friday the 13th. He goes, 'Sly, it's Stephen... He's gone.' I said, 'Who's gone?' He goes, 'Sage, he's gone.' I asked, 'Gone where?' He said, 'He died. He's gone. I'm sorry.' Click." Lulu Garcia-Navarro: "That's how you found out?" Sylvester Stallone: "That's how. 'He's gone, dead, sorry.' ... About a week later, I was all alone in my room, and a wail came out of me that I've never heard before or since. There was just such pain and grief and guilt it was not human. It really wasn't... No, you don't get over that." How do you ever recover from a loss delivered that coldly?
