One possible reaction could be Tony's heartbreak. He might feel betrayed and angry, leading to a rift in his relationship with Steve. He could also become distrustful of others in the future.
One way could be through communication. Steve could come clean to Tony about his feelings for Bucky and apologize sincerely. Tony might be able to forgive Steve over time if he sees that Steve is truly remorseful.
One possible reason could be Steve's strong sense of loyalty to Bucky. Maybe he feels that he owes Bucky so much after all they've been through. He might be so focused on helping Bucky or being there for him that he unconsciously ignores Tony.
I think this kind of fanfic can be quite controversial. In the Avengers universe, Steve and Tony have a complex relationship, and adding such a plot of 'cheating' with Bucky can change the whole dynamic. Some fans might like it for the drama it creates, but others might feel it goes against the original spirit of the characters' relationships.
One reason could be Steve's long - standing friendship with Bucky. They have a deep history together, and in the fanfiction, that bond might be portrayed as stronger than his relationship with Tony. Maybe Steve feels a sense of loyalty to Bucky that he can't ignore.
At first, it might be a bit rocky. Tony, being used to his own space, might feel smothered by Steve and Bucky's over - protectiveness. But as time goes on, he'll start to see their good intentions. Steve's moral compass will inspire Tony to be a better person, and Bucky's loyalty will make Tony feel secure. Eventually, they'll become like a real family, with Tony looking up to Steve as a father figure and seeing Bucky as a cool older brother.
There's also 'Forging New Bonds'. This fanfic focuses on the post - conflict relationship between the three. It explores how they start to understand and accept each other better. The writing style is quite vivid, making it easy to picture the scenes in your head.
One reason could be jealousy. Maybe Tony has been spending more time with one of them, and the other feels left out and jealous. For example, if Tony has been helping Steve with some high - tech projects and Bucky feels ignored, it could lead to a fight. Another reason might be a misunderstanding. They could misinterpret Tony's actions towards each of them. Say, Tony gives Steve a special gift, and Bucky thinks it means something more than just friendship, leading to a fight.
The fanfic alters the perception of the characters in multiple ways. Steve's reputation as a trustworthy and noble character is at stake. His actions of 'cheating' are not in line with what fans usually expect from him. Tony, who already has a complex personality, now has another layer of being wronged added to his character. Bucky, who has his own set of issues in the official stories, is now part of this love triangle that further complicates his image. It shows how fanfics can reshape the understanding of beloved characters in unexpected ways.
In Steve and Bucky and Tony fanfiction, the relationships themselves are a major element. Steve and Bucky's long - standing friendship, Steve and Tony's often - tense relationship, and Bucky's role in relation to both. Their backstories play a huge part too. For example, Bucky's time as the Winter Soldier. The stories might also focus on how they deal with power, like Tony's high - tech power, Steve's super - soldier strength and Bucky's combat skills. And of course, the setting, whether it's in the Marvel universe or an alternate one, can add different flavors to the story.
Friendship is a very common theme. These three characters often form a strong bond in fanfiction, relying on each other for support, whether it's during battles or in dealing with personal issues. For example, in many stories, they help each other overcome their past traumas.
