Well, it could be that Varys thought Dany was becoming too much like the tyrants she opposed. So he tried to take actions against her. Dany, being a powerful and often ruthless character in these stories, wouldn't tolerate such betrayal and thus killed Varys. For example, if Varys was spreading rumors about Dany's sanity or her ability to rule, Dany would see him as a direct threat to her claim to the Iron Throne.
Their relationship could also develop in a more complex way where Sansa starts to play Littlefinger at his own game. She may start to use his own tactics of manipulation against him, leading to a shift in the power dynamic between them. It could be like a cat - and - mouse game where Sansa is slowly turning the tables on Littlefinger.
In some fanfictions, after killing Varys, Dany may start to question her own actions more. Varys was a complex character, and his death might make Dany realize the extent of her power and how easily she can take a life. This could lead to internal conflict within her. On the other hand, it could also make her more determined to achieve her goals. She may think that by eliminating threats like Varys, she is one step closer to the Iron Throne and ruling Westeros. But at the same time, she might lose some of the support she had from those who respected Varys or saw him as a necessary part of the political landscape.
One great 'Game of Thrones' Varys fanfiction is 'The Spider's Web'. It delves deep into Varys' past and his motives in a really interesting way. It shows his early days in Essos and how he came to be the master of whispers in Westeros. The author does a wonderful job of staying true to his character as we know it from the show and books.
One key element is the power dynamic. Varys is a powerful figure in Westeros, so how the reader character relates to his power is important. Another is the element of secrecy. Varys is full of secrets, and the reader may be trying to uncover them or be drawn into them. Also, the political backdrop of Westeros is essential. It provides the context for their interactions.
There are fanfictions that focus on Varys' true motives. Maybe he wasn't just a power - hungry manipulator but had a grander plan for the realm, like trying to bring about a more democratic form of government in Westeros. In these fanfictions, he could be secretly training young minds to be future leaders who would break the cycle of war and tyranny.
Well, in A Dance with Dragons, Varys's story concludes in a rather unexpected and dramatic way. He's caught in the middle of power struggles and his actions catch up with him, leading to his demise.
Common themes in these fanfics include the corruption of innocence. Sansa starts as a somewhat innocent girl, and Littlefinger's influence is a form of corruption. Her journey to resist that corruption is a big part of the story. Another theme is the search for identity. Sansa is trying to find out who she really is in the midst of all the chaos and Littlefinger's manipulations. And finally, the theme of loyalty is there. Sansa has to decide where her loyalty lies, whether it's with Littlefinger for a time or with her own family and the North. Littlefinger, on the other hand, has no real loyalty except to his own power - hungry self.
The relationship between Sansa and Littlefinger in fanfic can be seen from multiple angles. Littlefinger is a master of manipulation. He thinks he can control Sansa easily. But Sansa is not as helpless as he believes. In some fanfics, their relationship is a battle of wits. Sansa is learning the ways of the game of thrones from Littlefinger, whether she likes it or not. And Littlefinger, while trying to use her, also has to deal with Sansa's growing independence and intelligence. This complex relationship can lead to various plot developments in fanfic, such as Sansa outsmarting Littlefinger in political intrigues or Littlefinger making a last - ditch effort to regain control over her.
