Melissa Hastings (Torrey DeVitto) is back in town and acting sketchier than ever, if that's even possible, but on Pretty Little Liars Season 5, Episode 3 (“Surfing the Aftershocks”) Spencer (Troian Bellisario) will finally confront her big sis about some of her latest lies, as we can see in a tantalizing new sneak peek of the episode.

This two minute clip from tomorrow's episode is beyond juicy. It opens with Spencer watching the DiLaurentis house, only to be interrupted by Melissa, who warns her not to catch "them" looking. Apparently Melissa thinks their families are still pretty much at war, as if they were the Borgias and the Medicis. Ah, DiLaurentis-Hastings tensions. Some things never change in Rosewood.

The sisters quickly go from historical comparisons to current questions. Like, why did Melissa lie about seeing Toby in London? She claims it's just because she wanted to keep Wren out of her story, and there's no real difference between having actually seen him, and knowing he was there. Do we believe her?

There's not much time to think about it, because the convo quickly circles back to the neighbors across the street. Melissa isn't pleased Ali is back in town, and she tells Spencer in no uncertain terms to stay away from the DiLaurentis family. Why? Are there secrets she's afraid her little sis will unearth? Why exactly are these families so at odds?

Check it out for yourself here!
