The new liars are ready to come back for the second season of the Pretty Little Liars reboot, and they’ll be joined by one original show star. Released last year in HBO Max, Pretty Little Liars: Original Sin brought a new group of protagonists to the franchise, introducing also a new and very creepy version of the main villain, A.

After a good run for the first batch of episodes, the streaming platform renewed the show for a second season, set to arrive this year. Now under the title of Summer School, the liars will reunite in a very different scenario, but with the same big problem ahead of them: the appearance of a new A who will make their lives miserable. The good news is, they won’t be dealing with it alone!

Through the official Instagram of the series, it was announced that Annabeth Gish will return to the world of Pretty Little Liars to play Dr. Sullivan once again, whil also letting their followers know the second Season is now in production:

"The doctor will see you now. Annabeth Gish is back as Dr. Sullivan. Pretty Little Liars: Summer School is officially in production."

Dr. Sullivan first appeared back in Pretty Little Liars season one, after the parents of the original liars chose her to help their daughters deal with Alison’s death. She later returned in seasons three and six, so the character is a very familiar face for any Pretty Little Liars fan.

What to Expect from Season 2 of Pretty Little Liars Reboot

Pretty Little Liars: Original Sin cast Maria Reficco, Bailee Madison, Chandler Kinney, Zaria Simone
HBO Max

Pretty Little Liars: Original Sin followed a group of girls from Millwood High, apparently with no connection between them besides going to the same school. When a mysterious hooded person starts chasing them and trying to expose their secrets, they find out that 20 years ago, their mothers were involved in a tragic event, and they’ll have to deal with the consequences of that in the present.

At the end of the first season, it seemed like the girls finally got rid of A and were ready to return to their normal lives, attending summer school. But as it happened in the original series, they’ll probably be a new person wearing A’s mask in order to make them suffer once again.

Pretty Little Liars: Summer School will see the return of stars Bailee Madison, Chandler Kinney, Zaria, Maia Reficco, Mallory Bechtel, Sharon Leal, Elena Goode, Eric Johnson, Alex Aiono, and Lea Salonga.
