The Halloween episode (Season 3, Episode 13: “This Is a Dark Ride”) of Pretty Little Liars was full of many surprises, including a huge, creepy cliffhanger at the end involving a human hand. What happened in that final scene?

In the final tag of the episode, we saw a hand reach out of the dirt in the foundation for a gazebo. This is the same foundation that we saw Alison and Byron talking in front of in a flashback to the night Ali was killed. The hand was most likely a flashback, since we don’t really know of any missing bodies/people in Rosewood at the moment.

We know that Ali went missing before she died, and that her dead body was found in her backyard, where the gazebo was being built. The hand is most likely Ali’s, but we have another theory. The hand could belong to Ali or her twin Courtney (who appears in the PLL books) and was killed by the other twin. That would explain Ali’s odd behavior in the flashback in this episode and her trying to convince certain people that she’s dead.

Who do you think the hand belongs to? Sounds off below.
