The thought of sharing his space with a reptile was clearly sending James into a tailspin. He was sitting on the edge of the sofa, his posture stiff, as if bracing for impact. He’d never been a fan of lizards, but for his roommate, Sarah, he’d be willing to take one on.

"It needs a heat lamp," he was repeating, his voice tight. "And special food. And what if it bites me?"

Across the room, Emily was practically bouncing. She’d always wanted a pet lizard, and James's dramatic expressions were a source of profound satisfaction. *This is going to be amazing*, she thought, hiding her giggles behind her hand.
