In Two Scenarios, I summarized two scenarios because I thought that, at one point, the text was ambiguous between these two accounts. However, I should have quoted some of the purportedly ambiguous passages. I am not going to search through the text right now to find them.
I am drawn back to the chapter where Alma reads Herbie (see here). I will possibly reread that chapter and find more details to post about. Having walked through (most of) the Historical Edifice from front to back, we can now reenter it from another angle.
