Beth Quinn: All that moving around, it must get lonely, huh?

Frank Castle: I had this friend, said that… we’re all lonely. And all life is, is just trying not to be.

Beth Quinn: I’d say that’s… spot on. It was a woman who told you that, wasn’t it?

Frank Castle: Yeah, it was.

Beth Quinn: I’m not lonely right now.

Frank Castle: Yeah, I ain’t lonely either.
