Well, a plot could involve Alfred trying to stage an intervention for Bruce. He invites all of Bruce's old friends from his pre - Batman days. But Bruce, in his mad state as Batman, thinks it's a trap and things go haywire. Or perhaps in the fanfic, there's a strange occurrence that makes Bruce and Alfred swap minds for a while. Bruce as Alfred has to deal with the day - to - day tasks while Alfred in Bruce's body tries to understand what's driving Bruce's madness as Batman. Another idea is that a mysterious figure from Bruce's past resurfaces and Alfred has to help Batman deal with it while also dealing with his madness.
In this context, Alfred's character could be developed through his relationships. His relationship with Mad Bruce could be shown as a struggle between his love for Bruce and his concern for Gotham. He might also form new alliances in the fanfic, for example, with other members of the Bat - family or even some of the villains who he realizes can be useful in curbing Bruce's madness. His skills as a strategist and a medic could be enhanced, as he uses them more frequently to deal with Bruce's erratic behavior and the resulting chaos in Gotham.
Another possibility is that Bruce is making moral decisions in the fanfic that Alfred doesn't agree with. As Alfred has his own set of values and he has been around Bruce for a long time, if Bruce starts to cross certain ethical lines in the name of justice, Alfred would be disappointed.
One possible reason could be that Bruce is being too reckless in his Batman activities. Alfred, being the caretaker, might see Bruce endangering himself unnecessarily and decides to punish him to make him more cautious.
One reason could be Bruce's increasing isolation. Alfred sees Bruce pushing away friends and allies in the fanfic. This makes Alfred disappointed because he knows that Batman needs a support system. Without it, Bruce is more likely to burn out or make hasty decisions that could have been avoided with some input from others.
Maybe Alfred is disappointed because Bruce in the fanfic makes some unwise decisions as Batman. For example, he might take excessive risks that could endanger his life or the safety of Gotham in a way that goes against Alfred's advice.
One idea could be that the OC is a childhood friend of Bruce's who has a unique skill, like being an expert in ancient martial arts from a far - off land. They could influence Bruce's training and view on justice in a different way. For example, they might introduce him to more spiritual aspects of combat and self - discovery.
Another form of punishment could be emotional. Alfred might give Bruce the cold shoulder, refusing to offer his usual words of wisdom or emotional support. This would make Bruce feel isolated and force him to reflect on his actions.
A more complex plot could involve Barbara creating a new technology that could potentially change Gotham for the better. But there are those who want to steal it for evil purposes. Bruce and Barbara then have to protect the technology while also trying to figure out who is behind the threat. This could lead to some intense action scenes and also some tender moments between them as they grow closer through the shared experience.
One reason could be that Bruce is being too reckless in the fanfic. Alfred has always been there to keep Bruce safe and if Bruce is constantly putting himself in unnecessary danger as Batman, Alfred would be disappointed. For instance, if he jumps into a fight without proper preparation or a well - thought - out strategy.
One possible plot could be that Batman and Alfred have a fundamental disagreement about Batman's increasingly dangerous methods. Alfred, fearing for Bruce's life, tries to stop him from a particularly risky mission. This leads to a physical altercation where Batman, in his single - minded determination, lashes out at Alfred. However, they soon realize that their fight is born out of love and concern for each other.
