"I love how Nico just pops up out of nowhere with a plan to save the day. Like, he just appears with his abundance of knowledge on how to solve everyone's problem:
• 'You should swim in the River Styx, Percy'
• 'I know where the House of Hades is'
• 'I can shadow-travel the statue and prevent the war'
WHERE THE [HECK] DID YOU COME FROM NICO?!"

NOT TO MENTION HOW HE HELPED CAMP HALF-BLOOD WIN THE FIRST GREAT WAR BY SUDDENLY APPEARING WITH AN ARMY OF SKELETONS AND KICKING BUTT!
