Autharyx paused thoughtfully when Viltez offered the bed. He was pretty sure he didn't much care whether he slept on the couch or the bed, but it might be impolite to reject the offer. It had never even crossed his mind to let any of his human guests anywhere near the place he used to rest. In fact, he much preferred they had no idea where he was when they weren't doing their trading. It was a little disconcerting to be trusted this easily. Not that he was planning to hurt the human, but still...

"I would be glad to accept the offer," he eventually said, hoping he didn't misread anything. It seemed to him that Viltez seemed slightly nervous about his presence in the house, but he didn't quiet dare to ask. Thankfully, the other men kept talking before Autharyx would have had to fill up the silence, and he listened with rapt attention. As the tail swept back and forth, his eyes were drawn to the shine of the blade at the tip. He'd assumed it was a weapon of sorts, but Viltez hadn't described it as such yet. 

"That is indeed a fascinating story," Autharyx said earnestly when the other was finished. "And even though it was involuntary, it is still a part of you, right?" He tilted his head as his eyes flicked to the tail once again. "If you were to close your eyes it would not know where to move, and if you do not wish harm on anyone, it would probably not react." He set his hand on the table, palm facing upwards in much the same position as when he'd touched the tail last. He felt slightly silly about doing so, but if he could tempt the appendage into coming back he would count it as a win.
