They might be shocked. In many cases, when a character like Jaune is betrayed in fanfiction, the RWBY characters could initially show disbelief as they've come to know him. It would disrupt their view of the group dynamic.
It can show the depth of their friendships. If Jaune is betrayed, it tests how far the RWBY characters are willing to go for him. For example, if Ruby really considers Jaune a close friend, she'll do whatever she can to support him and get to the bottom of the betrayal.
Well, it's a bit of a strange concept. Ruby might be really confused and blush a lot. Weiss would probably be scandalized and immediately condemn it as improper. Blake might be more understanding of the existence of such fanfiction but still a bit uncomfortable with it.
Well, Jaune in RWBY fanfiction can vary a lot. Sometimes he's the underdog who overcomes huge challenges, and other times he might have unique powers or a special backstory.
It could be because Jaune is a relatable character. He starts off as a bit of an underdog in RWBY. So, fans like to write stories where the other characters notice his potential and become obsessed with him as he grows.
One idea could be that Ruby and Jaune are partnered for a special mission outside of Beacon. Ruby's speed and combat skills combined with Jaune's strategic thinking could make them a great team. For example, they might be sent to investigate a mysterious Grimm activity in a far - off village. Ruby can quickly scout the area with her speed, while Jaune plans their approach based on the information she gathers.
One possible secret could be about his family heritage. Maybe in the fanfiction, Jaune has a hidden connection to a powerful family in the RWBY universe that he's kept under wraps for some reason, like to avoid unwanted attention or because of some family feud.
His character could become more self - assured. Jedi are known for their confidence in their abilities, and Jaune might gain that as he masters Jedi - like powers.
In the 'rwby reacts to the future fanfiction', RWBY might have a range of reactions. Ruby could be full of curiosity, eager to learn more about what the future holds for her and her friends.

Yang, on the other hand, might be more vocal, either expressing her approval or her doubts loudly. They would all be influenced by their own personalities and experiences up to that point in the story.
