Marty McFly: [referring to Alternate 1985 Biff] How could he be your husband? How could you leave dad for him?
Old Lorraine: Leave dad? Marty, are you feeling all right?
Marty McFly: [shouting] No! No I'm not feeling all right! I don't understand one damn thing that's goin' on around here and why nobody can give me a simple straight answer!
Old Lorraine: Oh, they must have hit you over the head hard this time.
Marty McFly: Mom, I just wanna know one thing. Where's my father? Where's George McFly?
Old Lorraine: Marty... George... Your father is in the same place he's been for the past 12 years... Oak Park Cemetery.
