Kanuna hesitated, wanting to protest and not accept the hospitality, but he decided he'd follow Sam's requests. It was the least he could do. And it was just a beer. So he stepped into the kitchen after him and took the bottle. Kanuna's posture was in no way submissive or fearful, he wasn't that kind of wolf, but he did keep a respectful distance so as not to inadvertently trigger any of Sam's wolf-inclined instincts over territory.
He drank from his own bottle after Sam had had his and the refreshing cool beverage helped towards quenching a thirst he hadn't realized he had. "I know," he said after a moment. "I know I should have. I thought, when it first happened, that the other werewolves in the tribe would step up and help you. Teach you. But you didn't stay long enough for them to even know you'd been turned. And I sure as hell am too big of a coward to tell them."
He shook his head and snorted in self-depreciation. "So I followed you, figuring I'd step in when you needed me, but..." but clearly he never had until now.
