I've always suspected the DS has a 'book'.
A literal book that has the codes and the procedures and the ideals and mantras, symbolism, secret comms definitions, tactics, contingencies, [maybe even their overall plan] etc. in it.
In order for a book to work, you'd have to give access to it to DS players.
Q talks about [their] playbook.
Q also says 'these people are stupid' and 'symbolism will be their downfall'
Almost as if /ourguys have a copy of it.
How stupid would you have to be to distribute documentation on your secret society?
When Swiffer says "by the book" in quotes like that, I suspect she's talking about that particular book, not the classic definition of 'by the book'.
How else could you get all these people (the countless army of the DS) to follow the same paths?
I'd give anything to own a copy of that book
if it exists
