[[WMG:Monsieur Gaston will ascend the French throne.]]
He's the current French heir and hates Richelieu's guts. Also, we just happen to have a bunch of Huguenot assassins running around. Perhaps they will make an attempt on Richelieu, and get King Louis instead. Richelieu, of course, will promptly get the hell out of Dodge. [[HeelFaceTurn Defecting to the USE]] would be too obvious, but he could go elsewhere, possibly joining the Dutch Hapsburgs, or even try to carve out an empire of his own in the New World.
* There's also the option of joining up with Pope Urban.
** Here's a terrifying thought: Cardinal Richelieu as the head of the Jesuits.
* There have been some hints that Richelieu is trying to get his new protege, Cardinal Mazarin, together with Anne of Austria, Queen of France, so that the baby who OTL would become Louis XIV can be conceived and brought into the world (given that Louis XIII is very probably gay and in any case hardly ever sleeps with Anne; OTL there's been much speculation that Mazarin was, in fact, the father of Louis XIV).
* As of ''The Cardinal Virtues'', Gaston is King of France, but his legitimacy is being called into question, as Queen Anne gave birth to a son on the day that Louis XIII died.
[[WMG:If Gaston becomes King of France, he will become a popular [[MemeticMutation meme]] amongst the Up-Timers.]]
* ''[[Disney/BeautyAndTheBeast Nooooo oooone Rules like Gaston! / Is the King like Gaston, / Averts Timelines and Succession like Gaston!]]''
** Well, he did become king, but given his anti-uptimer policies, the song is likely to be highly uncomplimentary.
[[WMG:The Spanish colonies in the New World will break away far earlier than they did in our timeline]]
The USE is soon to deploy a new blue-water fleet that, while still composed of sailing ships, will be far more powerful than the current ships of the Spanish and French navies, and there would be plenty of good reason to use those ships for commerce raiding. So there is an opportunity for some ambitious governor to pull a [[Literature/HonorHarrington Sepoy Option]], and establish a new sovereign nation in the New World.
* In fact, assuming Eric doesn't use a historical character for the purpose, he might just call the guy [[ShoutOut Barregos]].
* ''Seas of Fortune'' has the USE starting a colony in the Guianas, which Dutch privateers are using as a base to strike against the Spanish. ''Commander Cantrell in the West Indies'' expands on the naval war against the Spanish in the Caribbean.
[[WMG:In the next book taking place in Italy, Borja will learn exactly how the future remembers the organization he leads.]]
Come on. The fact that they've had two books so far with the head of the Spanish Inquisition as BigBad, without any uptimer making a single Creator/MontyPython reference indicates superhuman control on the part of the authors. Sooner or later it's got to happen.
[[WMG:Murad the Mad will become the new BigBad]]
First, his invasion of Austria will succeed, bringing the Ottomans into direct contact with the USE. Then, Murad will do the smart thing and go after Italy. The USE won't intervene at first, since he'll just be fighting their Spanish enemies, but if Murad can take Rome (and if the Portuguese and Catalan rebellions go off), he'll quickly become a clear and present danger.
* Or the new Big Good. There could be much amusement in Austria going to the USE and calling for a truce and temporary alliance to hold off the heathen muslims only for the USE to shrug and say "what should we have against muslims?"
** Murad might try to snag Bohemia first.
[[WMG:There's one person who won't be [[ButterflyEffect butterflied away]].]]
You may remember that Gustav gave Julie Sims a barony in Lappland as a wedding present. It's not inconceivable that she might retire there. And eventually, her line will produce UsefulNotes/SimoHayha.
[[WMG:The cover-ups of Huguenot crimes will be discovered.]]
There may be hell to pay when it is discovered that Mike Stearn's and some of his Jewish advisers used several acts of terrorism by Protestants to punish anti-semites. Considering the important figures later murdered by the Huguenots in their attempt to start a war, it may well be seen by some as sacrificing the safety of Calvinists, Lutherans, and Catholics in favor of Jews, witches, and the French. Of course anyone who found this out and tried to tell others might not be believed or ends up being murdered.
* Presumably Operation ''Krystallnacht'', the COC action aimed at wiping out anti-Semitism in the Germanies in the wake of the Dreeson Incident, is what's being referred to above. However, the Huguenot extremists had absolutely nothing to do with that. In fact, they've been operating, ever since ''1634: The Galileo Affair'', as ''antagonists'' to the USE, which they despise for its policies of religious freedom, especially toward Catholics. It hardly seems likely that the USE would try to cover up any atrocity that Michel Ducos and his gang committed.
[[WMG: The USE boxing championship will be named after Hans Metzger.]]
He was adored by the spectators, respected by the other boxers, and died undefeated when he was murdered for refusing to cooperate with people trying to rig a match - and killed or maimed every single one of the people sent to murder him before he went down. The combination of skill, sportsmanship and integrity he showed will be held up as the example of what a champion boxer should be.
[[WMG: Spain will eventually make a HeelFaceTurn]]
Borja will screw up again, prompting Philip to snap, throw his support behind Urban, and order the troops that took Rome for Borja to take it ''again''.
** Ol' Gaspar is already on very, very thin ice at the Escorial. Philip was, and is, furious with Borja over the whole Rome fiasco, and offers him any support or endorsement only for purely pragmatic political reasons (don't forget that the Spanish Inquisition is basically the secret police of the Spanish monarchy, and Philip relies on its support to keep his regime a going concern). If and when the Netherlands formally breaks with Spain, and given that, as of the end of ''1636: The Viennese Waltz'', Austria has more or less declared for the legitimate Pope Urban, Philip might well conclude that continuing to support the usurper isn't worth being isolated from the other branches of the Habsburgs, not to mention most of the rest of Catholic Europe, particularly with the Ottomans on the rampage.
** The Netherlands branch of the Habsburgs don't like Borja either, for the same reasons as the Austrian branch. The only nations of note that back Gaspar's claim to the Cathedra are Spain and France under Gaston.
