In the second half of this episode, after Harper storms out of the sub station kitchen, Zeke grabs the teddy bear cam and starts talking to it. The freezer/lair door in the background is open in the color shots and closed in the black and white "cam" shots.
When Zeke regains consciousness after getting kissed by Harper, she, Alex, and Justin are standing over him. In the shots of their feet, Justin is on Harper's right and Alex is on her left. In the shots of Zeke's pov looking up, Justin is now on Harper's left and Alex on her right - and they're all kinda standing in a circle. In the shot of everyone together, the three are standing next to each other with Justin back on Harper's right and Alex on her left again.
When Mason leaves the party and tosses the map with the eye holes on the floor, it lands with the holes facing the lower left corner of the screen. When Harper enters the room, the map has moved, so the holes now face the upper left corner of the screen.
