"Sam wants to share with you, you know," Cas shrugged. "You don't have to try. You've always been there when things got tough. You've done it before. He wants to know you've got his back, without a doubt. It's what you're good at. We both know you'd go the distance for him."
Sam cocked his head. "I think you're scared to be tender with him 'cause someone will that you're weak. Somewhere you learned that was weak. Probably because women do it easily. Well, it's not weak. It's just necessary sometimes. If it's necessary do it, You feel it anyway. You're not lying or anything. Sam won't think you're week for being honest with him, I promise you that."
Sam didn't judge like Dean did. It was one of the things Sam liked best about him. "Sam probably already knows you feeling anyway," he shrugged again.
