"Haku."
Stomach tightening at that harsh tone calling his name, commanding his unconditional loyalty, Haku managed a decisive, "Yes."
"Come here."
Haku stood at once and went over to Zabuza. Haku as much as he'd trained to keep his feelings in check, couldn't hide his surprise when Zabuza touched his forehead.
"You have a fever," Zabuza said flatly.
He frowned and Haku readied himself for a strong punch to the gut. Zabuza had never hit him before, and even though Haku was sure he deserved it, the thought made him sad.
So Haku bowed low from the waist. "I'm sorry for the inconvenience."
Zabuka chuckled lowly. "Ah, Haku, the same as ever. Go to sleep, I shall keep watch tonight. Tomorrow we shall find a hotel."
Haku bowed again. "Thank you for being so understanding. I shall go to sleep right away." He waited for Zabuza to dismiss him.
"Good night." Zabuza's gaze returned heavenwards and Haku found a comfy patch of grass to lay his head.
