Abigail watched the large marine pick the boy up off the ground like he was picking up a pillow, and slung the limp form over his shoulder.  Without looking around to see who was looking at him, the man started walking.  Abigail, too curious about the lad who tried picking a fight with the marine, to leave him to his fate, followed.  At first she did so from a distance, but the closer they go to the marine's prison, the closer she got. Not once did the man ever look behind him to see if there was someone following him.  Not once did his body posture give any tell tale sign there was something of interest in the world him.  It was obvious the man was too certain of himself to be give thought to someone trying to get him by surprise.

Was he human?  Yes, she was sure a part of him had to be, but was that part the majority or the minority of his body.  As she followed, she kept replaying the things that the people had told her, about the fight.  The kid had gotten in the first punch, which from everyone involved, should've done some degree of damage, even to abs of steel, but that wasn't the case.  The boy's fist hit, everyone saw it hit, but instead of going in, and pushing out all the air from the man's body, the fist just bounced back.  Stomachs didn't do that.  Sure, maybe someone had enough muscle control and strength to take a punch, and maybe harden around it, she could see that happen, but causing the arm to bounce back?  No.  A human body wasn't capable of left that.  

This left just one possible reason.  The man had eaten a devil fruit.  It was certain.  Which one though?  There were so many, how could she possibly guess which?  "Bouncing stomach."  She muttered under her breath.  "Bouncing.  His body was rubbery."  The only one that came to mind was the gum-gum fruit.  "It has to be that one," but it didn't since she didn't know all the fruits by heart.

Someone called to the man.  She didn't know who they were, but they were marines, so their personal identity didn't matter.  They saluted the man, licking his boot, and said they were supposed to take the prisoner to his cell.  They took him from the skunk, and Abigail followed them the rest of the way to the prison, wondering how she'd get the man out.
