His friends would be very worried. Shiemi, for example, would probably bring some herbs that she thinks might help with the fever. She would be gentle and try to make Rin comfortable. Izumo, on the other hand, would be a bit more brusque but still concerned. She might scold Rin for not taking better care of himself while also trying to find a solution to his fever.
A fanfic that stands out is 'The Three - Voiced Ensemble'. This one delves deep into the relationships between Rin, Len, and Miku. It explores not only their musical collaborations but also their personal growth. The author does a great job of showing how they support each other, like when Miku gives advice to Rin on how to improve her high - notes, and Len encourages them both during a tough musical competition. It's a long and engaging fanfic that really captures the essence of these three characters.
One possible reason could be fear. Rin might be afraid of his own powers and the potential harm they could cause to Yukio. Since he cares about Yukio, he may choose to run away to protect him.
Well, without reading the specific fanfiction, it's hard to fully analyze the plot. But generally, if Rin runs away in this story, it could be due to various reasons. Maybe he has some inner conflicts or misunderstandings with Yukio. It could also be related to his identity as a demon and the pressure that comes with it in the context of their relationship.
Naruto would probably be very surprised. He has heard about Rin from Obito and Kakashi. So when he actually meets her, he might be at a loss for words at first.
One characteristic could be the exploration of an unlikely relationship. Since Naruto and Rin are from different storylines in a way, it makes for an interesting exploration of how their personalities might interact. For example, Naruto's determination might contrast or complement Rin's own qualities.
Often, these fanfics highlight the contrast between Rin's modern - day mage nature and Saber's chivalrous, medieval - like essence. They play on the idea of two very different characters coming together.
Both of them might also feel a sense of unease. Seeing a version of themselves from the future could make them realize how much they are changing and how uncertain their future really is. It could also make them question their current identities and goals. They might start to have an internal struggle as they try to reconcile their present selves with the potential future versions they are seeing.
The idea of sacrifice also pops up a lot. Given the nature of the Fate series, the characters may be in situations where they have to sacrifice for one another. In fanfics, this can be explored in different ways, like Saber sacrificing her power to protect Rin and Shirou.
One popular 'Saber x Rin x Shirou' fanfic is 'The Three's Bond'. It beautifully weaves their relationships together in an alternate universe setting. The story shows how they support each other through various challenges.
