He was willing to betray his own kind. Why would he not betray us as well?
Perhaps, but he could be useful prior, in his desperation to stay alive. We still know very little of the invaders. Captives can answer questions, but they cannot easily inform us of what is normal to them. And if we can win him over, so that he follows willingly, he would be invaluable for a subtle infiltration.
You hope for too much. He does not hate his people. Even now, even as an outcast, even willing to kill them for his own profit, he does not hate them. He can be bought perhaps, but he will not stay bought.
I must try. A key to winning the loyalty of the invaders is central to my plan. We don't know it yet, but we must find it out.
Saashala opened her eyes and looked at the others, then the human.
"Walk with me a little, to where we can see the road."
She led him away from the firelight and sought out the thin winding strip of the caravan trail below.
"I have had to accept the help of beings that are simple and savage," Saashala remarks to him quietly, looking at the road intently. "I believe we have that in common, you and I. Now I do not know what you want from your existence, but I assume you wish it to continue, at least for the moment. My companions see you as a waste of time at best, or a liability."
The yuan-ti turned her eyes to gaze unblinking at the man. "Others have thought that of me, and I have shown them otherwise. It is my hope that you and I will have that in common as well. Help us against this caravan, and you will be paid for your efforts...and may leave, a free man. Return to whatever awaits you out there."
She extended a hand, as she'd seen others do for one another on greeting. Her hand was slim and delicate; no yuan-ti did manual labor, not even the purebloods.
"Agreed?"
