"Why me?" Grimm demanded. "Why not Carlson? Or are you saving him for your daughter?"
Carlson grabbed Grimm by the shoulder and spun him around. He drove a hard fist into the stout man's face.
Grimm stumbled backward. He fell at the cave's entrance. His hand, sprawled behind him to stop his fall, closed over a rock. He flung it at Carlson from a sitting position. It caught Carlson in the shoulder.
Gritting his teeth, Carlson charged at Grimm. But Ro moved more swiftly. He caught the white man and forced him back.
"This is no time for fighting," he said. "When the Oan are defeated you can kill each other. But not until then."
Grimm brushed himself off as he got to his feet
"Okay," he sneered. "I'll go with the red man. But when we meet again, it will be a different story."
Carlson turned to Ro.
"I'll go with you," he said. "Grimm can go with Charlotte and the professor."
