This week with our Liars, the secrets, lies and blackmail aren't far from them as both their own investigation into Nolan's murder and that of Dana Booker's heats up. With the Liars suspecting someone close to them, what will they be able to do about it, and will all of them be able to keep a clear head? As Ava prepares for a Vogue interview, Caitlin volunteers in a charity drive and Dylan prepares to write a piece of music, they try to keep their head above water and off Dana Booker's radar, but it's not that easy when she's convinced that they're involved in Nolan's murder and they're still trying to grieve.
Elsewhere, Mona has to revisit some of her old tricks after she's locked out of BHU's networks, and she may not have forgotten everything she once knew. Mona is also on hand to offer advice to Alison whenever she calls and their dynamic of confidantes is absolutely one of the highlights of the show.
Over the course of the episode Alison conducts her own investigation into Nolan and she may just start adding up that Taylor Hotchkiss may be a lot more alive than people think she is. Ali has fully settled in to her new role now of protector of the new Liars and it's an interesting change of pace compared to the original.
We also have another cello version of a Lady Gaga song this week. Any guesses on which one? Pretty Little Liars: The Perfectionists airs Wednesdays at 8.00 on Freeform.
