Does he think I don't know that? Blind Seer thought, before reminding himself that the answer was very likely "yes," especially given the last quiet bit. He growled to himself, then stepped back.
He looked back towards Firekeeper, who was still making a slow but steady pace away from them, snorted pointedly, looked back at Robin, snorted again, and shook his head in a deliberate "no". He clacked his jaws once, snorted again at Robin, and (wincing as he did so) laid down in an impersonation of one dead and closed his eyes for a brief second. That humiliation done, he quickly got back up, and indicated Firekeeper again, then (with some difficulty, finally settling on nodding his head a few times and stamping one foreleg) himself. He clacked his jaws again, then shook his head "no." He cocked his head to the side, as if to say "Do you understand?"
He hoped that Robin would get the implication: she will bite you, you will die, she won't bite me. He would hate to have to go through a repeat performance, wolf dignity being what it was.
