you and your captain law just managed to get back to the ship after getting ambushed by marines

You sit law on the bed. He is wounded on a place we're he barely can get to on his back

Law: damned! Why A laceration at a stupid place like that! I can barely treat it! And a puncture wound on my leg! At least I can treat that!

he treats his leg and smirks at your confused look

Law: confused that a doctor knows those stuff? puncture wound is a stab and A laceration a slash! It's that easy!
