Things in Rosewood are getting complicAted — and to quote Hanna, the Liars don't deal with complicated very well. So when Ashley Marin is moved to a state prison, Hanna gets desperate and comes up with a plan to take the blame for Wilden's murder with a little help from her former BFF — and current frenemy — Mona.  But when the plan gets derailed, Mona takes things into her own crazy hands.

Did Mona really just take the fall for Wilden's murder? Whoa. We didn't see that one coming! But we're happy that Mona finally payed Hanna back for all of the tormenting she put her through over the last three seasons. So it's back to Radley for Mona — but will she stay there? As much as we want to see Ashley Marin come home, we really just want to close Wilden's murder case. At this point, we know whoever killed Wilden probably knew about his crooked ways. Plus, it looks like he wasn't just using women for sex — he also covered up the real cause of Toby's mom's death for a price. 

Thanks to a police file Spencer got her hands on, filed by Wilden, we find out Marion Cavanaugh supposedly fell to her death... from the roof, not her window. So if Wilden faked her death report, how did Marion really die? Was it a suicide? Or did the mysterious blonde push her off the roof? Now, Spencer is convinced Wilden's blood is on someone else's hands — someone who knows what happened to Marion. 

Meanwhile, Emily’s old boss Zoe (guest star Rumer Willis) resurfaces and offers Em a way out of Rosewood for the summer. Upon hearing the news, Pam Fields has an emotional breakdown and sobs into Emily's arms. (Yeah, we cried too. It was tough to watch.) She's under a lot of stress and the thought of Emily leaving her for a summer was too much for Pam to take. She's lost everything, and now she's losing her daughter, too. 

As for Aria, well, she goes on a non-date with Jake after he helps her track down Mike. OK, so maybe it was a date, but Aria isn't ready to call it one yet. There's some serious Ezra/Aria/Jake drama ahead. It’s been too long since we’ve seen a triangle heat up, and the fire is about to start!
