** Percy doesn't have the ability to stay dry underwater as he does in the books, as it would likely be difficult and time consuming to dry Walker off after every underwater scene.

** Percy's sword was named "''Anaklusmos''" (Greek for "Riptide") when he received it in the original novel, but it's yet to be named in the show.

* AdaptationalLateAppearance: Rather than appearing to Percy and Grover as Percy is leaving Yancy Academy, the Fates appear at the Arch in Episode 5 in front of Grover and Annabeth.

** The NextTimeOn of the seventh episode has Percy saying a variant: "Hold fast, Mom."

** Percy is much more in line with his literary counterpart in terms of personality, complete with [[DeadpanSnarker his trademark penchant for snark.]]

** [[spoiler:Hades mentions that his Helm was stolen "Days" before the Bolt and that he figures whoever stole the Helm used it to steal the Bolt. In the books the Bolt and the Helm were stolen from Olympus at the same time because Hades only ever comes to Olympus for the winter solstice.

** In Episode 6, the older satyr Augustus tells Grover in the Lotus Casino that he's extremely close to finding Pan. While it turns out he's delusional under the hotel's influence and talking about a VR game, [[spoiler:the books eventually reveal that Pan ''is'' hidden in the state of Nevada... it's just that he's hours away from Vegas]].

* MeaningfulEcho: "Hold fast, Perseus. Brave the storm."

Later, in the same episode, she says an altered version of it to Percy before sacrificing herself.

** [[spoiler:On leaving the Lotus, Percy himself drives all the way to Santa Monica (albeit aided by the fact that they stole Hermes's car and can travel their instantly). The original novel had them pay a cab driver with a card that had seemingly infinite money on it from the Lotus.]]

** [[spoiler:At the beach at Santa Monica, the nereid Percy meets informs him that he's too late, and that the Summer Solstice has passed; Zeus and Poseidon are heading to war. In the original novel, they got to Santa Monica the day of, with hours remaining. Furthermore, the water-spriit gives him ''four'' pearls instead of three-- enough to save himself, Annabeth, Grover, ''and'' his mother. In the book, he was only given three.]]
