The Marty that enters the Nexus today looks -- less than happy. He's not full-on enraged, but he is pretty ticked off about something. He keeps clenching and unclenching his fists and grumbling to himself about "dickheads who made that shit. . ."
He stops by one of the ever-present couches and favors the sign with a small glare before looking around. "What the hell do you do when you find out that somebody made a cartoon based on you and your friends and managed to completely screw your personalities up?"
Yes,
Marty McFly discovered the BTTF Animated Series. And as you may guess, he wasn't impressed.
