"Ha ha ha! Mine is an evil laugh!"
Zoe scrutinized the dinosaur. "Don't sound that evil to me."
"Zoe, come on..." Wash made the dino climb up to her bare shoulder and growl in her ear. "Grrr! This is one evil T-Rex."
Zoe somehow managed to laugh and look skeptical and like she was enjoying herself at the same time.
"He could cannibalize you without a morsel of remorse," Wash said seriously.
"No he couldn't." Zoe took the dinosaur and narrowed her eyes at it. "He ain't human."
"Oh." Wash looked slightly disappointed for a moment, then brightened. "Oh well, I guess I'll just have to do it..."
He pounced on her, and their laughter echoed in the narrow confines
of their bunk.
