Michael Rooker: William Rice
Roland : [about David's mother, who he realizes is a Paladin] When's the last time you saw her?
William Rice : She split when the kid turned five.
Roland : Five. Oh.
William Rice : [opens door] Haven't heard a word since. If I hear anything, I'll be sure to give you a holler.
Roland : [closes door] No, you won't.
William Rice : No, I won't.
