With original author Rick Riordan on board, Disney+ series Percy Jackson and the Olympians is poised to be one of the most faithful adaptations of a book series in recent history. In some ways, the series can be even more faithful to the original myths than the books could. In Episode 3 of the new fantasy series, Percy, Annabeth, and Grover come face to (veiled) face with one of the most iconic villains in myth, but her story veers from the original books in a way that makes her much more interesting.
