Ep 21. Hush, Hush, Sweet Little Liars

In the season 6 episode 21 of Pretty Little Liars, titled "Hush, Hush, Sweet Little Liars," the stakes are higher than ever for our beloved Liars. As the show approaches its season finale, the girls are finally starting to unravel the truth behind who "A" really is - but in true PLL fashion, things are never quite what they seem.

The Liars are still reeling from the events of the previous episode, in which they were all trapped in a creepy and dangerous "dollhouse" by their mysterious tormentor. As they try to come to terms with what happened, they realize that they may be running out of time to unmask "A" once and for all.

Complicating matters is the fact that the Liars are under fire from all angles. There are the usual suspects - Aria's former flame Ezra, Spencer's ex Caleb, and the suspicious Detective Tanner - but they are also being targeted by a new adversary. This person is using the hashtag #CharlesIsComing on social media, and seems to be determined to take down the Liars once and for all.

The title of the episode itself is a reference to the fact that everyone seems to be keeping secrets from one another. The Liars themselves are trying to hide their own dark pasts and secrets, even as they attempt to decipher the secrets being kept from them. And of course, there is the ever-present question of who "A" really is - and what they want from the Liars.

As the episode progresses, the tension only grows. Aria is confronted by someone from her past, while Emily and Spencer find themselves face-to-face with a chilling new development. Hanna, meanwhile, is forced to confront a difficult truth about her former friend Mona.

Despite the darkness and danger that surrounds them, the Liars continue to band together and support one another. They know that they are stronger together than they are alone, and they are willing to do whatever it takes to stop "A" once and for all. But as the episode draws to a close, they realize that they may have underestimated their adversary - and that the danger they face is greater than they ever could have imagined.

"Hush, Hush, Sweet Little Liars" is a tense, suspenseful episode that will keep viewers on the edge of their seats from beginning to end. With its twisty plot, shocking revelations, and heart-pounding action, it is a fitting prelude to the show's explosive season finale.
