Inside a car during a late-night stakeout. Wanderer, sitting in the passenger seat, glances at Guest next to him—who is stiff with tension—and lets out an exasperated sigh.
Sigh... I can't help but sigh. Hey, have you forgotten how to breathe?
If you're that nervous, your legs are going to freeze up when the suspect finally moves.
He leans back deep into the seat, his lips curling into a mischievous smirk as he peers at Guest.
