I believe that this question is asking about events that transpire in chapter nine. When the chapter begins, Roy is warned that Dana is out to get him, so Roy is forced to come up with a plan to avoid that unfortunate confrontation. Roy thinks that if he stays in sight of teachers until moments before the bus leaves, then Dana won't have any opportunity to exact revenge. The plan almost works too. Roy waits until four minutes before the bus is supposed to leave, and he plans to cut through the gym in order to make it on time. Roy tells us that he almost made it too. Unfortunately, Roy did not make it to the bus because Dana ambushed him from a janitor's closet.

Dana Matherson had reached out and snagged Roy as he ran toward the gym, pulling him into the closet and slamming the door.

Roy thinks that he is in big trouble, but he is saved by Beatrice.
