^^Actually he woud've still had the mark because this story proabably happened before the SoN. So Percy still had the mark so.....yeah.....I think it would be funny to see Carter react to Percy's sword fighting since he's really good and Carter like, specializes in combat right? So to see him get beat by Percy would be kinda funny to me....
