We caught the special ep before it airs on ABC Family tomorrow night, Oct. 19, at 8 p.m., and we’re giving you the lowdown on what to expect.

The episode revolves around Noel’s Halloween bash in 2008, before Aria, Emily, Hanna and Spencer became pretty little liars! Allison’s alive in the whole episode, and she has a big secret she’s been keeping from the rest of the girls. We’ll leave the tricks to ‘A’ and give you a Halloween treat – we’re spilling our favorite OMG moments that will leave ya spooked.

OMG Moment #1: Allison’s alive! And there’s a big secret she’s hiding from the girls that we’re in on….

OMG Moment #2: ‘A’ sends out her first text. And it’s not to who’d you think…

OMG Moment #3: Who does Ali think she is, anyway? The episode shows us just how mean Ali was—she plays mind games with Aria and Spencer, and her Halloween prank goes awry. Totally uncalled for? Yup. Totally Ali? Of course.

OMG Moment #4: The girl with the best Halloween costume will surprise you. While Spencer, Hanna, Allison, Emily, and Spencer all wear amazing costumes, when you see Jenna’s costume, JAWS. WILL. DROP. I’m looking up where I can get her outfit as I type this out…

OMG Moment #5: There’s something about the creepy baby costume…and the fact that the person wearing it is stalking the girls! We counted three characters we saw wearing it, and we’re still debating who it is!
