How do the Logan kids get T.j to reveal what he knows about the "night men"?What does he do that make them feel relieved?

The Logan children feigned disinterest, which immediately caused T.J. to tell what he knew.

“Then don’t!” said Stacey with smooth finality, turning back toward the fire as if he cared not at all about the night men. Taking his cue, I nudged Christopher-John and Christopher-John nudged Little Man, and the three of us forced ourselves to stare into the fire in feigned disinterest.

The children were relieved that the attack was not caused by what they did to the school bus.

“Then it wasn’t ’cause of the bus?” Christopher-John blurted out.
