A plot twist could be that Daenerys loses her dragons after marrying Tyrion. This would be a huge change as her dragons are a big part of her power. It could lead to her relying more on Tyrion's political cunning. Also, there could be a twist where Tyrion is forced to choose between his loyalty to Daenerys and his family back in Westeros, creating a major conflict within him.
One possible plot twist could be that Tyrion discovers a secret about Daenerys' past that threatens their relationship. Maybe she has a hidden alliance or a family secret that could change everything. Another could be that political enemies try to use their marriage as a way to undermine them, forcing them to fight not only for their love but also for their thrones.
A plot twist might be that Daenerys and Jon Snow find out that the pregnancy is not a normal one. It could be that the child has some sort of special powers or abilities even before birth. This could lead to various factions either trying to protect or destroy the unborn child. Also, there could be a twist where the pregnancy causes a rift between them because they have different ideas on how to raise and protect the child in a world full of danger and political unrest.
One plot twist could be that they face opposition from the Soul Society. Since Ichigo is a substitute Soul Reaper and Yoruichi has a complex history there, the elders might try to stop the marriage for political or traditional reasons.
One plot twist could be that just before the wedding, Ash discovers a long - lost Pokemon that he has to take care of immediately. This could cause him to be late for the wedding or even make him question if he can take on the responsibilities of both a Pokemon trainer and a husband. Another twist might be that Lenora's old research comes back to haunt her. Maybe a powerful Pokemon she once studied breaks free and heads towards the wedding venue, forcing Ash and Lenora to team up and stop it before they can get married.
Well, a plot twist could be that one of them loses their powers right before the marriage. For example, if Ichigo loses his Soul Reaper powers, he might start to doubt if he can protect Rukia and their future together. Or perhaps Rukia is suddenly called back to Soul Society for an important mission that she can't refuse, and it's a mission that might keep her there for a very long time, putting their relationship to a hard test. Also, there could be a new character introduced who has a mysterious connection to either Ichigo or Rukia and tries to disrupt the wedding.
One possible plot twist could be that their marriage is part of an undercover mission. For example, they need to pretend to be a married couple to infiltrate an organization. This would add an element of danger and secrecy to their relationship. They might have to deal with unexpected situations where their cover is almost blown, and they have to rely on their quick wits and mutual trust to keep the mission going.
A plot twist could be that Ayame is actually part of a prophecy related to Naruto. For example, their marriage is foretold to bring either great prosperity or great disaster to the Hidden Leaf Village. This makes their relationship more than just a love story and puts a lot of pressure on them, as they have to figure out how to fulfill the prophecy in a positive way.
Well, a plot twist could be that they get married but then Rei's body starts to deteriorate in a way that was unexpected. This could be due to her not - so - human nature. And Shinji has to struggle to find a way to save her while dealing with the fact that their marriage might be short - lived. Also, there could be a plot twist where another character is secretly in love with one of them and tries to break up their marriage. For example, Asuka might have some hidden feelings for Shinji and tries to create problems between Shinji and Rei.
One possible plot twist could be that a long - lost relative of Elena shows up to oppose the marriage. Maybe this relative has some ancient grudge against the family that Elijah is from. Another twist could be that a powerful witch casts a spell on Elijah, making him forget his love for Elena right before the wedding. Then Elena has to go on a quest to break the spell.
Well, a plot twist could be that Pan discovers she has some special power right before the wedding. This power might be something that no one in the Saiyan family has had before. It could make her question her identity and whether she is worthy of being with Trunks. Or perhaps Trunks is forced to go on a sudden mission and is presumed dead, but then returns just in time for the wedding in a very unexpected way.
Well, perhaps a plot twist could be that Naruto gets cursed. This curse makes him forget all about Ino and their relationship. Ino then has to go on a journey to find a way to break the curse. Along the way, she might face many challenges and meet new characters who either help or hinder her. Or maybe there's a twist where it's revealed that Ino was arranged to be married to someone else in her family long ago, and she has to fight against the family traditions to be with Naruto.
