My first reaction to that thing in Nice Guy’s arms was to wonder what in the world such a noisy, wiggling alien was doing in my world! It hadn’t seen me yet, so I probably could have returned to my Home Place without its knowing I was there. However, this was MY world and I felt I needed to make a stand and let it know who was in charge.
My second reaction was to decide that, since Nice Guy was holding it, the possibility of it being too dangerous was probably low. I decided to take a chance, and I hopped into the clearing, never taking my eyes off of the intruder.
