One way is to put them in life - threatening situations that force them to rely on each other completely. This could be like being trapped in an enemy base during the Age of Ultron chaos. They have to depend on each other's skills to escape. As they do, they start to open up more about their feelings, and their relationship grows deeper. Also, adding some emotional conflict, like Natasha being afraid to get close to Clint because of her past, and Clint trying to break down those barriers can further develop their relationship.
In fanfiction, their relationship could be developed by introducing external factors that test it. For instance, if a new villain targets them specifically because of their relationship. This would force them to fight together and protect each other even more. Another aspect could be their relationship with the other Avengers. If some of the Avengers are suspicious of their motives, Wanda and Pietro would have to rely on each other for support. Also, exploring how they handle Pietro's sometimes over - eager nature and Wanda's more cautious approach. They could learn from each other and grow closer as a result.
Their relationship could develop through shared experiences. For example, fighting side by side against Ultron's forces would build trust. Steve might admire Natasha's skills and her ability to adapt, while Natasha could be drawn to Steve's unwavering sense of justice.
They could have a deep conversation about their dreams. Aladdin could share his real long - term dreams beyond just being rich and marrying Jasmine, and Genie could talk about his desires if he were truly free. This would bring them closer on an emotional level.
One idea could be exploring Clint and Natasha's past missions more in - depth. Maybe there were some unspoken feelings that emerged during a particularly dangerous mission before the events of Age of Ultron. Another could be a fanfic where they get separated during the chaos in Age of Ultron and their journey to find each other again, facing new enemies and challenges along the way.
The relationship could develop through moments of vulnerability. For instance, Natasha could be injured during a mission, and the reader takes care of her. This shows a softer side of Natasha and makes the reader feel closer to her. Also, they could develop their relationship by having inside jokes. These little things can create a sense of intimacy. And then there are the serious conversations they might have about life, death, and the future of the Avengers. Through these exchanges, they come to understand each other on a deeper level.
The relationship can develop through their shared anticipation of the baby. Steve can become more in tune with Natasha's emotions, and they can have deeper conversations about their future as a family. For example, they might talk about how they'll raise the child, whether they want a traditional or more unconventional upbringing.
They could be given a task that requires them to rely on each other completely. Let's say they have to find a lost heirloom in a far - off land. Along the way, they share stories from their childhoods that they haven't told before. Rapunzel tells Flynn about her lonely days in the tower in more detail, and Flynn opens up about his early days as a thief. This deepens their bond.
Darcy can be developed further by being put in more high - stakes situations. For instance, she could be the key to solving a major crisis that the Avengers are facing. This would force her to step up and grow. Clint could be developed by having him make some tough moral choices. And with Darcy around, she could be the voice of reason or the one who challenges his decisions. Their relationship could also develop further by having them go through a rough patch. Maybe there is a misunderstanding between them, and how they overcome it would show their growth as characters.
They could have more deep conversations about their future as a family. For example, discussing how they want to raise their children, what kind of values they want to instill. Also, showing them supporting each other in small daily things, like Lucy helping Natsu with his reading skills and Natsu helping Lucy when she has a tough day at the guild. This would strengthen their bond on a more personal level.
A great way to develop their relationship further is to show them building a life together. They could start a project like building a lighthouse that has a special connection to both the land and the sea. It would be a symbol of their love and unity, and during the process of building it, they would face challenges, make compromises, and grow even more in love.
