* AscendedFanon: The names "podnought" and "SD(P)" for [[MacrossMissileMassacre missile pod-laying superdreadnoughts]] were originally {{Fan Nickname}}s used on Creator/DavidWeber's web forum. They got made official.
* {{Expy}}: The Five Mandarins, the five Permanent Senior Undersecretaries who lead the Solarian League, have a lot in common with ''Literature/{{Safehold}}'s'' Group of Four, also by Weber.
** Both are groups of TheManBehindTheMan, rendering the people who are ''supposed'' to be in charge effectively puppets.
** Both are faced with a smaller enemy who is ''far'' more technologically advanced than they are.
** Both are highly focused on their own survival in the short term, and are thus making decisions that will prove disastrous in the long term.
* RetCon: [[http://honorverse.wikia.com/wiki/Great_Resizing The Great Resizing]], a mass revising of the ship sizes presented in the Honorverse which became necessary because WritersCannotDoMath.
* WhatCouldHaveBeen: The Honorverse was originally going to be timeskipped several decades, following the death of its namesake character. Her children would have continued the action. The Creator/EricFlint collaboration ''Crown of Slaves'' nixed this original plan; its espionage plot ended up fast-forwarding the conflict by putting pressure on the Mesans to enact their plan early. As a happy side effect, Honor was spared, cutting off what would probably have been the [[TheyChangedItNowItSucks greatest fan rebellion]] in modern Sci-Fi literature.
* WordOfGay: [[http://forums.davidweber.net/viewtopic.php?f=1&t=4508&p=112492#p112492 Word of Weber]] is that Admiral Mark Sarnow is gay (and happily married), though the mention of it never makes its way onscreen. One forum poster did, however, note that it could potentially explain why Pavel Young never accused Honor of sleeping with him.
* WriteWhoYouKnow: In ''A Beautiful Friendship'', the Harringtons have a meeting at a restaurant called "The Red Letter", owned by a person by the name of Creator/EricFlint. The fictional Flint is said to hail from the world of New Chicago, described as "a dumping ground for radical anarchists, socialists, and - especially - every member of the Levelers’ Association the government could round up after Old Earth’s Final War". The RealLife Flint, an occasional co-author with Weber in this and the ''Literature/SixteenThirtyTwo'' series, is a self-admitted socialist, and currently lives near UsefulNotes/{{Chicago}}. Also qualifies as a ShoutOut.
* Honor's actions in ''The Short Victorious War'', assuming command of the fleet after her admiral is incapacitated, rather than having an admiral aboard another ship assume command during a key moment in the pitched battle, is likely based on the actions of US Navy [[http://en.wikipedia.org/wiki/Bruce_McCandless Lieutenant Commander Bruce McCandless]] aboard USS ''San Francisco'' (CA-35) during the [[WorldWarII Naval Battle of Guadalcanal.]] Like Honor, Commander [=McCandless=] was decorated for his actions rather than court martialled (he was the seniormost surviving officer aboard ''San Francisco'', but by far not the seniormost officer in the task force), probably in large part because the outcome was an American victory against a larger Japanese force.
