Revealing mistake: When the main characters enter the underworld, there is a shot of them walking past a burning fountain. If you look closely at the shadows of the characters, they don't correspond with the lighting coming off the fountain.
Continuity mistake: When the bus passes Poseidon and he disappears, the people walking near him also disappear. There is an Asian couple walking from left to right across the shot that should have been still there after Poseidon is gone. Sloppy SFX that sort of spoils the effect of a god being able to vanish.
Chiron: Use this to defend yourself. It's a powerful weapon.

Chiron: Only use it in times of severe distress.
Percy Jackson: This is a *pen*.
