AHS clearly stands for the name of his school. But Percy being apart of the swim team isn't that weird. It's probably the only sport he can actually do well, even if he is cheating (though his teachers wouldn't know that). I would if they would allow children of the sea gods to be apart of a sport involving water in Camp Jupiter.
