[[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).
[[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!]]''
[[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 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.
[[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?"
[[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 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.
[[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.
