Garrett grins like he's got the world figured out, and takes a bite out of his enormous scone, and wonders why he just confessed to a child that he has some kind of dissociative disorder where he loses huge blocks of time.

BOX MTG

Hanna's dressed like Aria -- which is to say like Tippi Hedren at a speakeasy -- Aria's dressed like Spencer -- which is to say sensibly -- Spencer is dressed in a lovely gown, and Emily's wearing a cute denim jacket with intense cuffs.

Emily: "Okay but like you saw the video. Garrett looked in the box, and whatever he was looking at was weird. We like weird things, and A is obsessed with the box, so let's just leave Caleb in danger a little while longer."
Hanna: "I am going to keep bitching about this until something horrible happens to him. Also, though, we have an actual video of all our suspects going through the dead girl's shit in her bedroom and calling her a bitch..."

That Ali doll from Halloween's head pops open, revealing the original threat:

It's my turn to torture you. And there's more! Flip it over. You think you're safe on the outside, but you're not when I'm on the inside. And there's more! Flip it over again! That can't be right. Oh, they're all holding different threats. Got it. You scared yet? You should be, bitch. That's when it starts sounding familiar. The last one's on a bit of ruined cardstock, with a little blood on it: Next time it'll be your face, not this pumpkin.

FLASHBACK

She led them to her house after the prank, uttering these Jungian truths -- "I've never been this way before..." "Back alleys and backyards have always been the best way to my house..." -- and just as Ali was saying something bitchy about Melissa and Ian's relationship, they came upon porch carnage: Ruined pumpkins on Alison's porch, spooky choir singing, and a knife in the face of a pumpkin stabbed through an invite to Noel Kahn's Halloween party they'd all been at.

Alison made that sad face she always made about the NAT Club, but pretended to blow it off, and then -- although the Liars plead exhaustion, after her horrible prank -- she seduced them into staying, so she wouldn't be alone.

BUT

Aria turns up the corner, revealing A's signature, and the girls finally realize that A was after Alison long before she died. Awesome! Do you think this will come up again in the episode, even though it's massively important? Doubtful!
