First, focus on character development. Give your OC a unique backstory, personality traits, and goals. For example, if your OC has a troubled past, it can add depth to their relationship with Kaldur. Second, understand Kaldur's character. Know his values, his Atlantean heritage, and how he interacts with others. Then, create a plot that throws them together in interesting situations. It could be a mission where they have to rely on each other. Also, don't rush the relationship. Let it develop naturally over time through shared experiences and conversations.
One great Young Justice Kaldur x OC fanfiction is 'The Unseen Bond'. It delves deep into the relationship between Kaldur and the OC.

It can symbolize protection. Batman is the mentor, and when he carries Nightwing, it shows his instinct to keep Nightwing safe from harm, whether it's physical harm from villains or other threats.
In this fanfiction, often there's a power struggle. Nightwing, with his own set of skills and experiences independent from Batman, might oppose Batman on certain principles. Maybe it's about different approaches to crime - fighting. Nightwing could be more lenient while Batman is strict.
One great 'Nightwing' romance fanfiction is 'Love in the Shadows'. It beautifully portrays a relationship between Nightwing and a new character.

Well, perhaps in this fanfiction, Shield Tris is being misinformed. She might believe that Harry is in possession of something extremely valuable, like a powerful magical artifact. So, in her mind, kidnapping Harry is the only way to get that item. It could also be that she's part of a group that has a radical ideology and they see Harry as a threat to their plans, so they order her to kidnap him.

They think that by taking her into their custody, they can protect that knowledge and keep her safe from the real enemies who might want to use her.
