(Marty arrives at the McFly residence again only to see George knocked out of his chair)
Marty: Dad! Come on Dad wake up! (taps his face around)
George: Uh what?
Marty: Dad you're alright!
George: Son, what happened?
Marty: I don't know but that's not why I came here. I came here to inform you that mom is drinking again and was caught. Edna just demerited our family and gave me a second demerit for her thinking I actually drank out of her flask.
George: No way!
Marty: Check your cameras.
(George searches the cameras from earlier to see that Lorraine was in fact drinking and looked closer to see that it was an alcoholic drink)
George: You're absolutely right Marty! But when did I get knocked out and… holy cow! Where are my tapes!
Marty: They should be around somewhere (looks around) nope no where to be found except for this one. This is the only tape that was not stolen.
George: Then who must've took the tapes.
Marty: We can check the cameras again.
(George checks the cameras from earlier again but instead from outside his home)
Marty: That's Biff! And he has a bat! Great Scott! He just hit you with the bat and is stealing all of your tapes!
George: But Biff is not supposed to be acting like this!
Marty: Maybe the Citizen Plus thing didn't work out for him.
George: No Mart, that couldn't be true. The Citizen Plus Program has never been a failure on our citizens. Unless he was hypnotized to do this.
Marty: I'll try to get your tapes back! (runs to the DeLorean)
George: Thanks son!
