Percy Jackson and the Olympians Season 2 Episode 3 "We Board the Princess Andromeda", sets up a major plot point that will play a role in the future. The episode ended with Percy learning why the Olympians are cautious about him. Annabeth informs Percy about The Great Prophecy, something that was introduced later.Fans learned about The Great Prophecy in the last chapter of the third book, The Titan’s Curse. However, the makers of Percy Jackson and the Olympians Season 2 have decided to introduce much ahead in the storyline. The Great Prophecy plays a major role in the first five novels of the series.Percy Jackson and the Olympians Season 2: The Great Prophecy explained: View this post on Instagram Instagram PostEpisode 3, "We Board the Princess Andromeda", was about Tyson, Annabeth, and Percy navigating through the mysterious cruise ship the Princess Andromeda. They soon learn that this ship has monsters and belongs to Luke. However, unlike the book, the trio's confrontation with Luke is less hostile in this Percy Jackson and the Olympians Season 2 episode.They soon escape the ship on a lifeboat, and it is inside this lifeboat that Annabeth tells Percy about The Great Prophecy. She does not know the exact prophecy, but has a vague idea what it is about. She tells Percy that a child of the Big Three (Zeus, Poseidon, and Hades) would decide the future of Olympus on their 16th birthday.This is the explanation given even in The Titan’s Curse. However, the reader and Percy do not learn the entire prophecy until the last book, The Last Olympian. This is how the prophecy goes:"A half-blood of the eldest gods, Shall reach sixteen against all odds, And see the world in endless sleep, The hero's soul, cursed blade shall reap. A single choice shall end his days, Olympus to preserve or raze."While many initially believe that the Great Prophecy exclusively referred to Percy, this notion is challenged in the last paragraph of the final chapter of this book, and even in the third book, "The Titan's Curse". But it is ultimately Percy who makes a choice that changes Olympus in the final book, The Last Olympian.What has been happening with Percy Jackson and the Olympians Season 2?

In the same episode, Tyson is also revealed to be Poseidon's offspring, making him Percy's half-brother. But the central plotline of the season is the quest to retrieve the Golden Fleece, which can heal anything.Luke had poisoned Thalia's Tree (that repels monsters from the camp), thus the heroes are on an adventure to retrieve the fleece to heal the tree."When Thalia’s tree is mysteriously poisoned, the magical borders of Camp Half-Blood begin to fail. Now Percy and his friends have just days to find the only magic item powerful to save the camp before it is overrun by monsters. The catch: they must sail into the Sea of Monsters to find it. Along the way, Percy must stage a daring rescue operation to save his old friend Grover, and he learns a terrible secret about his own family, which makes him question whether being the son of Poseidon is an honor or a curse."Four episodes of the eight-episode Percy Jackson and the Olympians Season 2 are available on Disney+, with the fifth one, "We Check In to C.C.'s Spa & Resort", streaming this coming Wednesday.
