The series' second season began filming in April 2023. In May 2023, it was reported that filming for the second season has been delayed due to the writers strike.

Music
Film composer Joseph Bishara was hired to do the series' score for Original Sin. He is known for his work in horror movies, including the Insidious film series and The Conjuring franchise. A remix version of "Secret" by the Pierces appeared in the opening sequence. The original song was previously used as the opening theme in the original Pretty Little Liars, while Pretty Little Liars: The Perfectionists used a cover version by Denmark + Winter. In the second season, this time was covered by Transviolet.
Composer Ronit Kirchman was brought onto the Summer School season to score the original music. Kirchman's music, known primarily for her work on The Sinner, was recognized twice by IndieWire as a Best TV Score, where they state that "Kirchman is so deft at dialing up the dissonance in a way that, by the time anyone realizes that something's amiss, it's probably already too late."
The Original Sin and Summer School soundtrack albums are both available on WaterTower Music.

The series premiered on July 28, 2022, with the first three episodes available, followed by two more episodes each on August 4 and 11, and then the final three episodes on August 18.
