It’s hard to keep track of the Pretty Little Liars Season 4 filming schedule when we’re still waiting for the new season to start airing. Which is why it’s so great to have such an enthusiastic PLL cast and crew to keep us well-informed! Which Season 4 episode did PLL just start filming?

Season 4, Episode 8: “The Guilt Girl’s Handbook.” Nia Peeples (Pam Fields) tweeted a pic of the script cover, along with the line, “On the set of #pll this morning.”

What can we expect from Season 4, Episode 8? Well, we know Pam Fields won’t be the only Rosewood mom gracing our screens. Lesley Fera (Veronica Hastings) tweeted after the read-through for the ep, which means Spence’s mom will also be featured. We also know that Mona will be appearing, if this script spoiler is anything to go by. Is Mona still on Team Liars?

The episode was written by Jan Oxenberg, a newbie to the PLL family, which means we have no previous Pretty Little Liars episodes to compare her work to. Jan does have a long list of television writing credits, including Parenthood, Cold Case, and Once and Again, so we think she is up to the task!

Pretty Little Liars Season 4 premieres on Tuesday, June 11, 2013 at 8 p.m. ET/PT on ABC Family.
