HBO Max's Pretty Little Liars: Original Sin is all set to return this week with two new episodes, continuing the saga of the mysterious 'A,' as the unknown entity continues to threaten the group of teenage girls. Roberto Aguirre-Sacasa's latest take on the Sara Shepard novel series has been very successful so far, with the series crossing its halfway mark last week.The two upcoming episodes will also be the last set before the final three arrive on August 18, 2022. This odd release schedule has somehow worked really well for the network, and you can expect some big surprises in this week's set of episodes, as they will lead to the final week of the latest Pretty Little Liars spinoff. A recently released promo hints at some big developments for Minnie "Mouse" Honrada (Malia Pyles) and Faran Bryant's (played by Zaria) mothers.zaria@zariazariazariaQueen of mathematics on my tombstone pls twitter.com/AngelaWaters/s…PLL: OriginAl Sin@AngelaWaters@zariazariazaria queen of mathematics, can’t wait to stream and tweet with you25417@zariazariazaria queen of mathematics, can’t wait to stream and tweet with you https://t.co/Hw0eiea8N9Queen of mathematics on my tombstone pls twitter.com/AngelaWaters/s…The sixth and seventh episodes of Pretty Little Liars Original Sin will be released on August 11, 2022, at 12.30 PM EST on HBO Max.
