The Pretty Little Liars girls have been dealing with “A”’s presence in their lives for so long that we barely remember a time when they weren’t being stalked!

Well, that’s all about to change! We’re finally going to see what the fab four were like before their lives were run by creepy dolls. Check out five spoilers from the special edition prequel episode.

1. The little liars get ready to party! Noel Kahn (Brant Daugherty) is planning a killer Halloween party and all the liars are desperate to score an invite. Wait –– is this a universe where Aria (Lucy Hale) isn’t popular? We can see Hefty Hanna (Ashley Benson) and Nerdy Spencer (Troian Bellisario) being social outcasts, but Aria? No way. Will Ali get her little liars into Noel’s Monster Bash, or will they have to sit this haunted house party out?

2. There’s a new (old?) girl in Rosewood! Ali tries to get into the Halloween spirit, but there’s a new “It-girl” in town who’s totally killing her fright night buzz. Who does this noob think she is, and more importantly, does her name begin with an “A”? Hm.

3. Spencer runs for class president! Oh, Spencer. All we can say is: Nerd Alert!

4. Aria makes a shocking discovery about her dad! Wait... more shocking than finding out that he was sexing up of his students? Because that was definitely a jaw-dropping moment. We can’t imagine what Aria’s about to find out about her unfaithful daddy, but we hope it doesn’t involve a can of red paint and a collection of women’s Tory Burch boots.

5. Take note: This special episode is on a Wednesday! Ok, so this isn’t really a “spoiler” in the traditional sense of the word, but all PLLers should know that this very special episode will be on Wednesday, not the show’s normal Tuesday slot! As an added bonus, ABC Family is dedicating the day to all things PLL with an all-day marathon (starting at 11 am ET/PT).

Don’t forget to tune in for the special episode on Wednesday, October 19th at 8 pm ET/PT on ABC Family.
