If dead bodies could talk then all would be fine in Rosewood. But, unfortunately, things don’t work that way on “Pretty Little Liars.” The secrets are piling up and the girls don’t even know who to trust anymore in episode 17 of the Freeform series.

The synopsis for Tuesday’s installment, titled “We’ve All Got Baggage,” teases that “love is in the air in Rosewood.” But so is deception and revenge.

According to the episode description, a wedding will “finally” take place with a “special officiant’s help.” Who is tying the knot? Hanna’s (Ashley Benson) been putting off her wedding planning long enough. Maybe Jordan’s (David Coussins) surprising his fiancé with a spur of the moment wedding? Or perhaps Aria’s (Lucy Hale) parents, who recently got back together, will be exchanging vows. Whoever may be walking down the aisle is definitely not getting the attention they deserve because things are completely unraveling in Rosewood.

The synopsis adds that Aria will have to come clean to Ezra (Ian Harding) about her writing some of his book chapters. Will he understand her reasoning? Or will he see the move as a form of betrayal? Meanwhile, Spencer (Troian Bellisario) and Caleb (Tyler Blackburn) will be dealing with a devastating blow when something from the Hastings campaign leaks to the media. After the discovery about Veronica’s (Lesley Fera) illness last week, the leak could potentially be connected to the medical documents. But when Mona’s (Janel Parrish) involved, anything is possible.

The biggest jaw dropper of episode 17 will be the Liars finding out that Alison (Sasha Pieterse) has been hiding something from them.

“We all have a past, Hanna,” Spencer’s sister, Melissa (Torrey DeVitto), tells Hanna in the promo video. “Aren’t you curious what she plans to use against you?”

It’s not clear what Alison has up her sleeves – if she has anything at all. However, it’s clear that things are starting to get dangerous again. The teaser for episode 10 reveals that Emily may have found Charlotte’s (Vanessa Ray) murder weapon, and it appears as if the murderer, or someone else close to Charlotte, wants it back.

“Pretty Little Liars” Season 6, episode 17 airs on Freeform on Tuesday, Feb. 23 at 8 p.m. EST. Watch the promo video below:
