Percy Jackson and the Olympians

The Last Olympian

During the fight against Typhon, Dionysus was trapped under an abandoned mine. Looking for a party as his spirit lives at each one, Dionysus found that Bobby Earl was having a birthday party, despite the danger being faced by everybody. Percy Jackson is then brought there in a dream and Dionysus warns him about Kronos' power. He also tells Percy to make sure that his son Pollux gets through the war. Originally Percy thought that Dionysus could never be a loving father, but that changes his mind.
