Visible crew/equipment: After Reddington warns Liz of the Wendigo, he leaves, and the camera pans out. We see the entire set: Liz on the couch, the stage with the entire set, the theater seating, camera ladders, the lighting, etc. (00:04:40)
Suggested correction: This is a theatre used for plays, and it's Red's temporary safehouse for Liz. In the previous episode, The Djinn (No. 43), Red talks about this theatre owned by Gerta. Red says, "Her theatre is ours as long as we need it." So, Red and Liz are using it to hide out.
Visible crew/equipment: There are two men in the flat near Elizabeth, even though Elizabeth and Mr. Kaplan are alone in the room. (00:18:35)
