"I don't have time to rest," he finally admitted after the usual fuss of him denying, her staring into him. "I'm nowhere near you guys' level of awesomeness yet - if I stop for every little bug, how am I supposed to catch up?"
"In your own way," she said, and that finally was enough to get him to lie down.
(That, or the sedative she'd slipped into his tea. Who could say?)
