The waiting room buzzed with the low thrum of nervous energy. Amelia bounced on the balls of her feet, her hands clasped behind her back, a silly grin plastered across her face. The floral wallpaper seemed to bloom anew with every blink. She'd been waiting for an hour, but the delay felt like a secret, a thrilling little pause before… something.

"That's quite a show," he chuckled, a low rumble that vibrated through her.

"Just preparing for my starring role," Amelia chirped, feeling a lightness in her limbs that was almost giddy. She winked. "You?"
