memoir: rework bridge to dath ilan material; yank scrap to scrapfile

I had a lot of notes and prewritten prose sitting in the ancillary
post draft file, but I'm also trying to rip out dath ilan content from
pt. 5 (because the part that anyone cares about is me fighting 1-on-1
with Big Yud; the object-level literary analysis goes in the ancillary
post, and most words about me fighting other nobodies in the chatroom
gets cut).

Looks like this cuts 1700 words from pt. 5?
