The second person
The images show that the space through which the man crawls is a kind of lobby or hall. It could be a hotel lobby. In this lobby there is a counter with several computer screens. It seems as if the counter is unmanned, but if you look closely, you can see that there is indeed someone behind it.
Behind the counter is a receptionist wearing a black face mask. The reason she is blending in with the environment is that she’s fallen asleep. It was already 5 AM at the time of the recording, so she must have been at the end of her night shift. Or she started the day with a nap, that is also possible of course.
What does the receptionist have to do with the crawling man? You will read it on the next page!
