For an instant, there was only an eerie, distorted, rapidly growing silhouette, changing from blood-red to black as the boundary of the bubble cross-sectioned the intruding figure. Then they recognized the back of another long-haired warrior and realized that the audience on the other side of the bubble had probably seen him approaching for some time.
He bowed to the hooded figure and handed him a small bag.
"More atavistic cubs, big and little! Hold still, Cynthia," a new voice cut in.
Hal turned and saw that two cold-eyed girls had been ushered into the cubicle. One was wiping her close-cropped hair with one hand while mopping a green stain from her friend's back with the other.
Hal nudged Joggy and whispered: "Butch!"

"Then how is it, Hal," he asked, "that light comes out of the bubble, if the people don't? What I mean is, if one of the people walks toward us, he shrinks to a red blot and disappears. Why doesn't the light coming our way disappear, too?"
"Well—you see, Joggy, it isn't real light. It's—"
Once more the interpreter helped him out.
