A really interesting plot twist might be if Arya discovers that her pregnancy is part of a political plot against her or her family. This would force her to use her skills and wits to protect herself and her unborn child, similar to how she had to survive in the original series. It could also lead to her reuniting with long - lost family members or making new alliances. Well, in this fanfiction, she would have to navigate through a whole new set of challenges with the added responsibility of a pregnancy. She might even have to pretend to be someone else to keep her pregnancy a secret from her enemies. This would be a great way to see her character develop further in a different context.
A great plot twist would be if Arya's gag was part of a larger scheme by the Faceless Men. They could be testing her in a new and extreme way. Maybe they want to see if she can still carry out her assassinations without being able to speak or use her normal methods. This would put her skills and training to the ultimate test.
In some fanfictions, there might be a plot where Jaqen actually has a deeper connection to Arya's family than she initially realizes. Maybe he was secretly tasked with protecting her all along. This could lead to a series of revelations and a change in their relationship dynamics, from mentor - student to something more like comrades in a grander scheme.
A plot could involve Arya getting injured on one of her adventures. Gendry, who has a soft spot for her, takes it upon himself to nurse her back to health. During this time, they share stories of their past experiences. Arya tells Gendry about the strange and dangerous things she saw while being a Faceless Man. This closeness could lead to a romantic relationship as they both realize how much they mean to each other.
A possible plot twist could be that the dragons in Game of Thrones are actually the result of some ancient ninja jutsu from Naruto's world. Maybe a long - ago ninja experimented with a powerful jutsu that created these creatures. Another twist could be that Jon Snow has some hidden ninja blood in him, which gives him unexpected powers and abilities that no one in Westeros has ever seen before.
Well, perhaps a plot twist where the White Walkers are not the ultimate villains. Maybe they are being controlled by a more powerful and hidden force within Westeros. This would turn the whole 'fight against the White Walkers' narrative on its head. Also, a character like Tyrion Lannister could discover he has some sort of magical ability that has been dormant all his life, which would add a whole new layer to his character and his role in the story.
One plot idea could be that Arya, in her guise as a servant in King's Landing, catches Tywin's attention not for her identity but for her sharp intellect. Tywin, always on the lookout for useful tools, begins to test Arya in subtle ways. For example, he might ask her opinion on various political matters in a veiled attempt to see if she has any insights that could be of use to him. Another idea is that Arya, while still hating the Lannisters, realizes she can use Tywin to gain access to information that could help her in her long - term revenge plans. She has to balance her hatred and her need for secrecy while Tywin remains oblivious to her true nature.
One plot idea could be that Daenerys and Arya meet on the road. Arya, being the assassin she is, is initially suspicious of Daenerys. But as they start talking, they realize they both have a common goal of bringing justice to Westeros. Daenerys offers Arya a position in her court, which Arya hesitantly accepts. Together, they plan to take down the corrupt lords and make Westeros a better place.
One interesting 'Game of Thrones Arya' fanfiction could be one where she travels further east than she did in the show. In this fanfic, she might encounter new cultures, learn different fighting styles, and maybe even find a new purpose that's different from her revenge - driven one. It could show her growth not just as a fighter but also as a person understanding the world around her.
One interesting plot twist could be that a previously unknown witness emerges with evidence that completely exonerates Tyrion. Maybe it's a servant who saw the real culprit all along but was too afraid to speak up until the trial.
A great plot twist in such fanfiction could be that there is a hidden underground society in Westeros that has been secretly developing modern technology all along. When they finally reveal themselves, they use things like laser weapons to take over King's Landing. Also, what if Bran Stark's warging ability could be enhanced by a neural - link technology? He could control multiple animals or even people at the same time, which would give him an incredible amount of power and change the balance of power in the story.
