From the title of the episode (Season 3, Episode 13: “This Is a Dark Ride”) to the fact that it’s occurring on Halloween, we are very scared for what the next episode of Pretty Little Liars (airing October 23) will hold for the Liars.

And now, Spoiler TV has released a behind-the-scenes video that gives us a brief look into the taping of the drama. In the two-minute video, which was shot on set by Joseph Dougherty, who also wrote the episode, you can see the filming of the Adam Lambert concert aboard the train. The crowd seems to be enjoying it, with what appears to be a few creepy faces entering and leaving the frame at times.

Here’s what worries us: The size of the crowd and (we assume) the volume of the music. We all know that Adam likes to belt out those high notes. Will the Liars be able to hear or see if something goes horribly wrong? For example, if Aria (Lucy Hale) is taken and tied to some train tracks like in the promo?

The idea of the Liars being stuck on a moving train that they cannot get off of in such a large crowd is making us excited, scared and a little claustrophobic.

After watching the video, do you think the concert scene will be the beginning of something bad on the train?

Don’t miss the next new episode of PLL, the Halloween special, on Tuesday, October 23 at 8 p.m. ET/PT on ABC Family.
