Pretty Little Liars Season 6 Episode 15 Promo

Everything is about to change forever. 

The official preview for Pretty Little Liars Season 6 Episode 15 teases a whole lot of new drama for our favorite characters. 

Spencer and Aria will break into Sara's hotel room to find out if she could have had anything to do with the big murder, but will they find anything that will help put her in the frame?

While they're doing that, Sara visits Alison and lets her know that they didn't know everything about Charlotte. This could be the start of a brand new friendship. A toxic one. 

There also looks set to be a big fight between Mona and Spencer as Spencer struggles to believe that Mona is just an innocent bystander this time round. 

Then there's a crazy scene that looks like poor Emily is being held captive in a hospital. Yikes.
