When Danny starts his circuit of the 2nd floor above the Colorado lounge, it is about the area of the elevators. He passes Room 237 on his right. His return has him pass Room 237 on his left. This time he stops his big wheel and looks back at the room.
When Danny was doing is circuit of the Colorado Lounge and its neighboring hall earlier, on the first floor, the clip began and stopped at this approximate position in the service hall directly below.
As we can see all the doors are closed. And Danny’s circuit has shown all the doors to be closed.
We have a shot from below and behind of Danny looking back up at No. 237.
There follows a shot of Danny and the laundry bin and door at the far end of the hall.
Again, another shot from below and behind of Danny looking back at Room 237.
Return to Danny. He rises from his Big Wheel and approaches Room 237.
And did you notice that the door just beyond and opposite Room 237 is open now? I didn’t until today.
I dodged out the area of the door and as you can see it’s definitely open. The floor appears to be carpet perhaps like that in Room 237. I can’t tell. It is blue or blue-green. Curiously, if you really dodge it out, you see the brief bit of “room” beyond may be unfinished set.
Danny tries the door of Room 237 and finds it locked, looks up at its number and sees the twin girls. When Danny returns to his Big Wheel, he keeps glancing back at Room 237 over his left shoulder, which keeps our attention on Danny and his focus on the left. When he isn’t glancing back to the left he keeps his head down, looking to the floor, such as the image below of him passing the still open door.
It is only when Danny is back around the elevators that he lifts his head and keeps it up as he cycles, just as it had been up as he rode all around the floor before approaching Room 237.
