John and Sam in “Unfinished Business”

John

You gotta understand somethin'. After your mother passed, all I saw was evil... Everywhere. And all I cared about was.. was keeping you boys alive. I wanted you prepared. Ready. So somewhere along the line, I, uh... I stopped being your father. And I-- I became your.. your drill sergeant.

John

So when you that said 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

What?

Sam

We're not different. Not anymore. With what happened to mom and Jess... [laughs] ... We probably have a lot more in common than just about anyone.

John

I guess you're right, Son. [smiles]
