Start of the Quest
"Oh, hey... ah... Listen, no offense but, ah, I'm not really supposed to talk to strangers... And anyway, I'm in the middle of something here.
Griff's been trying to get me to join in on one of his crazy ideas, but I told him, I said "I need to talk to my dad about that", and he went even CRAZIER and sent his bionically-enhanced goons on me! Man, I just wanna to get out of town in one PIECE..." - Marty Jr. upon approaching him
During the Quest
"Will you quit following me? Griff will see you! Unless... Could you keep his gang off my back? Oh, man, now we've done it!" - Marty Jr. in the first part of the Quest.
"Can you believe that Griff said he'd knock me into to next week? Like time travel or something? Heh! What a goofy idea!" - Marty Jr. after the first part of the Quest.
"Oh no, it's Griff! Excute the possum defense!" - Marty Jr. at the start of the second part.
End of the Quest
"Did... Did we lose them? Whew, that's a relief. Ever since Griff had those bionic implants, it's harder and harder to stay out of trouble.
But I should be cool from here. That toaster-head can't wander too far without his implants overheating! Thanks, man!" - Marty Jr. upon finishing the Quest.
Escort Marty McFly Jr. and protect him from Griff Tannen by taking down others.
