The Setup for Future Seasons
Percy Jackson and the Olympians episode 4 teases a mysterious character who will be vital to two major storylines that Disney will not pay off for years. Thus far in Percy Jackson and the Olympians' four episodes, the setup for future seasons has been weaved mostly seamlessly into the story of season 1. For example, Percy Jackson season 1's nightmare sequences have adequately foreshadowed the future of the show without taking away the importance of the quest for Zeus' master bolt. Aside from including another nightmare for Percy where he is goaded by the recurring mysterious voice, Percy Jackson episode 4's other story reveals teased more adventures for future seasons of the show. Be it through the subtle hints Echidna made to a primordial goddess who will be important to Percy's future or the first contact Percy made with his father, Percy Jackson episode 4 was filled with vital scenes concerning the upcoming journey of the titular character. Another tease, however, was directed toward Grover, with Percy Jackson episode 4 setting up two major storylines for upcoming seasons.

Percy Jackson Episode 4 Sets Up The Lost Olympian Pan. The lost god of the Wild is set up in Percy Jackson episode 4. During a scene on a train in Percy Jackson and the Olympians episode 4, Percy, Annabeth, and Grover witness a herd of wild Centaurs. Grover explains that there used to be thousands more Centaurs and other wild creatures roaming the wilderness before the god Pan went missing. Pan was the Greek god of the Wild, dedicated to protecting nature across the world only to go missing when humans began destroying the environment. Grover also explains that Satyrs who succeed as Protectors - successfully leading demigods to Camp Half-Blood or completing quests - become Searchers. Searchers are dedicated to finding the lost god Pan so that he can return and restore the natural order of the Earth's environment. While this storyline will not have much of an impact on Percy Jackson and the Olympians season 1, the search for Pan will greatly impact future seasons of the show should they be greenlit. Percy Jackson season 2 has not yet been confirmed by Disney, though the promising viewership numbers and critical reception of the show will likely lead to a continuation of the story.

Pan Will Be Important To Two Future Stories In Percy Jackson & The Olympians. Pan's story will be reopened in future stories based on the original Percy Jackson books. Concerning how Pan will be important going forward, the lost god of the Wild will have more of an impact in Percy Jackson seasons 2 and 4. At the end of Percy Jackson and The Lightning Thief, Grover is granted the title of Searcher after successfully aiding Percy in his quest to find Zeus' master bolt. Between the events of the first and second books, Percy Jackson and The Sea of Monsters, Grover embarks on a massive adventure to find Pan yet goes missing. It is revealed that Grover was drawn to the titular Sea of Monsters by a presence he thought was Pan, only to be lured to the island of Polyphemus, a Cyclops who feeds on Satyrs. While Pan does not have a direct influence on the second Percy Jackson book, the search for him by Grover kickstarts Percy and Annabeth's quest to save their Satyr companion. In the third book, Percy Jackson and The Titan's Curse, Pan's presence is felt by Grover when the latter hears the former say 'I await you' during the third book's quest. This leads to the fourth book, Percy Jackson and the Battle of the Labyrinth, in which Grover feels Pan's presence in the titular Labyrinth. Eventually, Grover finds Pan hidden in the Labyrinth, where the god of the Wild says he was waiting for Grover as the Satyr has been chosen to continue the deity's work of restoring nature. Grover subsequently becomes the Lord of the Wild, solidifying his quest that began in The Lightning Thief, the same quest teased in Percy Jackson and the Olympians season 1, episode 4.
