Nia Peeples’ (Pam Fields) latest tweet has us seriously worried about our Pretty Little Liars. The Rosewood mom posted to Twitter yesterday (May 28), “Just wrapped from #pll. No pics today. Pam's been crying since 7 am. Poor Pam.” What has Pam crying?

Whatever it is, it seems like it will be going down in Season 4, Episode 8: “The Guilty Girl’s Handbook,” based on the script cover page Nia tweeted two days ago. The PLL cast and crew were hard at work on the eighth episode of the season until at least yesterday.

It also sounds like it won’t just be affecting Pam and/or the Fields family. Nia’s follow-up tweets said, “A hard day for #pll” and “Spent the rest of my day recovering from the #pll drama.” Yikes! Could this PLL drama include Veronica Hastings, as well, who will also be appearing in the episode?

Or could it have anything to do with the aftermath of Season 4, Episode 7: “Crash and Burn, Girl”? Both Shay Mitchell (Emily) and writer Bryan Holdman tweeted about the epicness of this episode. Shay said, “You will not believe what happened!” Does something bad happen to Emily? It would certainly explain Pam’s tears in the following episode...

Why do you think Pam is crying? Does something happen to Emily? Let us know your theories in the comments below!

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