Continuity mistake: When Josh throws the piece of fruit (or whatever it was) to break the lamp, Audrey checks out the lamp stand. In the shot where Walter first arrives and she's checking it out, it's all in one piece. But in another shot, it's suddenly all broken and a big piece is missing.
Visible crew/equipment: In the scene that Drake and Josh return to their room with B-a-a-a-b, the lamb is startled and jumps off the couch. As Drake is running to catch it, a crew member's hand is momentarily visible waving on the left side. (00:20:25)
Chosen answer: It's just a screaming fan that knows everything about Drake.
