Francis will get poisoned.A guard mentions he doesn't let people taste his food for poison since he don't want it to get cold. Sounds like Foreshadowing to me...
The masked wizard is Turkey!I mean look at him! That or he's his unknown evil twin, since in that universe, the canon characters have that are not based on nations.
The jar that Italy got from Gupta? It will stop Natalia's death curse.The jar is said to ward off evil, after all.
Arthur's two living brothers are in league with the masked man.Well, he certainly seems convinced David is out to get him, so why not Jock and Patrick? Maybe one of them even is the masked man. (I presume it's David that is dead, but this could work whatever.)
- Not to mention Natalya told Alfred to blame the head wizard when she killed him. Does she know about the curse?
Why did Natalya take Feliciano and Alfred's bodies.Is there anyone suspicious of the fact that both Feliciano and Alfred's bodies were taken away by the villains? There must be planning to do something with them.
- This Tropette believes that Natalya wants to use them to help ressurect her and Ivan's dead big siser Either that, or turn them into Nobodies and send them after the main characters, either way, really.
The stone that made the Green Jewel is the same stone that made the jewel on Malachite's HandIf this troper recalls correctly, the Green Jewel greatly increases one's magical power and abilities. The jewel on the hand did more or less the same thing, and it's green to boot. Malachite could have found out about the alternate world and the powers of the stones, traveled through dimensions, and got a piece of the green stone to enhance his own magic. And considering the fact that he existed an incredibly long time ago, it was very possible for him to procure it before the stones were destroyed.
Italy, Kiku, and Ludwig are not really deadActually, Italy would be fine, since Natalya's death curse most likely would not effect him as a nation. On the other hand though, Ludwig and Kiku are probably Only Mostly Dead, and just "dead" enough to lose their status as users and, in the beginning of the third part, Italy will have to find a way to revive them
More of the characters will be replaced with nationsObvious WMG, one or more of the characters will be killed off and their nation counterpart will replace them.
Arthur's wife, Elizabeth, was Queen Elizabeth I in our world.One of her famous quotes was "I have already joined myself in marriage to a husband, namely the kingdom of England."
