Grover finds himself trapped in Polyphemus’ cave. Using his satyr powers and cleverness, he has to find a way out.Dior Goodjohn shines as Clarisse La Rue, daughter of Ares, who follows her quest to retrieve the Golden Fleece.

She plays the sorceress behind a lush island resort, but there’s more going on than just a fancy vacation spot. Circe lures people in, but the show twists things a bit. Instead of just trapping travelers, her spa becomes a training ground, pushing heroes to face and understand their own fatal flaws.Aleks Paunovic takes on Polyphemus, the giant cyclops from Greek mythology. On screen, he comes off as a shepherd who acts friendly at first, but that’s just a front. The show flips the character compared to the Odyssey or even the Percy Jackson books, where Polyphemus is more of a bumbling brute. Here, he is clever, and that makes him way scarier.Andra Day as Athena shows up in a flashback in Percy Jackson and the Olympians Season 2 Episode 5 to challenge her daughter Annabeth's hard work.

View this post on Instagram Instagram PostPercy Jackson and the Olympians Season 2 Episode 5 makes Annabeth and Percy take a much-needed spa day to examine their fatal flaw, but it turns out to be less relaxing than it sounds. After their ship is blown up, they are washed into the hands of Circe and seem to be visiting the equivalent of a godly perfect getaway for half-bloods in need of rescuing. But the retreat’s true purpose may be much more sinister.It's a really smart choice to combine the plot points of Circe's spa in The Sea of Monsters book with the Sirens storyline on the show. There is no link between the two in the Percy Jackson book, but on the TV adaptation, Circe uses her spa to train heroes to identify their fatal flaw, which the Sirens then exploit to lure them with their song.Percy Jackson and the Olympians Season 2 Episode 5 features some of the biggest book changes of Season 2 of Percy Jackson yet. The changes that have been made to Circe's character are similar to those made to Medusa in Season 1, and they both become better characters for it.Instead of simply being adversaries for heroes to overcome, they have a reason for their actions. The episode is delightfully designed: the ancient Greek architecture seamlessly blends the modern world of Percy Jackson with the magical one in a way that the show (and books) rarely allow.Episode 5 really shines when it comes to the Sirens. Instead of the typical beautiful temptresses, these Sirens are genuinely monstrous, haunting creatures who have trapped and eaten who knows how many people. Their call is chilling. And seeing Annabeth face them up close, you can actually see the tension.Percy Jackson and the Olympians Season 2 Episode 5 is now streaming on Disney+.
