The last person Otto had expected to see sprawled on the medical cot of his laboratory when he returned after his outing was Peter. His mask was off, and Otto could see the bruises and gashes across his soft, calf-eyed face, hair matted with sweat and blood. There were more gashes across the body of his suit, red in places that it shouldn’t have been. Otto could not immediately tell if he was breathing, and he hurried forward to make certain that he was.

“Hey, doc.”

Otto’s breath caught in his chest.

“Peter. Who–?”

Someone was going to pay dearly.
