This from "Dead Man's Blood":
John: I don't think I ever told you this but... the day you were born, you know what I did?
John: I put a hundred dollars into a savings account for you. I did the same thing for your brother. It was a college fund. And every month I'd put in another hundred until... anyway, my point is, Sam, that this is never the life that I wanted for you.
Sam: Then why'd you get so mad when I left?
John: You gotta understand something. After your mother passed, all I saw was evil, everywhere. And all I cared about was keeping you boys alive. I wanted you... prepared. Ready. Except somewhere along the line I... uh... I stopped being your father and I... I became your drill sergeant. So when you said that you wanted to go away to school, all I could think about, my only thought was, that you were gonna be alone. Vulnerable. Sammy, it just... it never occurred to me what you wanted. I just couldn't accept the fact that you and me? We're just different.
John: (smiling a little) What?
Sam: We're not different.
Not anymore. With what happened to Mom and Jess... well, we probably have a lot more in common than just about anyone.
John: I guess you're right, son.
Sam: Hey, Dad? Whatever happened to that college fund?
John: ... I spent it on ammo.
[Sam and John look at each other and start laughing.]
