"Shh!" He clapped a hand over her mouth. He shifted so she could feel the warmth of his lips on her ear, and even then she could scarcely hear his whisper. "Don't say that. You don't want them to know we're onto them."

"Quick, we don't have much time," he hissed. "Hurry, before it realizes our suspicions and tells the others!"
"Ohhhhhh-kay," she said. While she distracted the alien parasite, she wondered if he was crazy or brilliant.
