ENTITY AT THE BEGINNING OF THE FILM
[SPOILER ALERT, DO NOT READ FURTHER IF YOU DON'T WANT SPOILERS]
So, the entity we see killing the A-Sync employee at the beginning shouldn't be Pirate Clark, right? The creation of his entity version by the Backrooms would begin once he enters for the first time, wouldn't it? And at that point, he wouldn't have entered the Backrooms yet.
Although, thinking about it, there might already be an entity for absolutely every person who has ever existed, but we don't fully understand the fact that it's an infinite place. That would mean that even if there were an entity representing each person, few could cross paths due to the titanic scale of the Backrooms.
Do you think the creation of the "Pirate Clark" entity begins after Clark has already entered the Backrooms, or did he simply already exist there for some time?
