How does C. C. Hunter use imagery in Born at Midnight?

Imagery:

"Kylie's gaze shot out the kitchen window to the patio where she'd seen her mom earlier. There, a pair of her dad's tighty-whities dangled half out of the smoldering grill."

"Tearing her gaze away, she eyed the door and fought the urge to run. Run fast and hard. But face it, she had never been a good runner, and too many freaks stood between her and the door."
