Thanks Quisling, I
think I follow that! I had it as "one by one, we would be fired" meaning that the letters of WE are removed separately, but that makes 5 self-contained and doesn't account for the ellipsis. Your explanation is probably much better than mine, though the wording in 6 still doesn't quite work for me. Something like "...and the other would be a long time" works cryptically even if the surface doesn't.
