We arrived at school (or back at school in my case; Kyle had had free periods all morning so had the morning off and I'd gone to a local cafe to grab lunch) and saw Biff and his jock gang hanging around the yard. They spotted us and started whispering amongst themselves. I couldn't hear from where we were, but it couldn't be anything good for us.
Suddenly, Biff slugged Steve 'the Stud' Farber and started shouting at him. I didn't catch all the words but the jist of sounded like "leave them alone...under my protection...kick the shit out of you if..." And so forth.
Me and Kyle glanced at each other and headed to class. Fortunately, it was one that Biff and the Stud also had, so we'd be able to see any further effects.
