Well, they could start going on adventures together again. Maybe they'd face some old villains that they once fought as a couple. Their combined skills, Nightwing's acrobatics and detective skills along with Zatanna's magic, would make them a formidable team once more. They might also rekindle their relationship in a more private way, like having quiet dinners and reminiscing about old times.
One possibility is that they get back together and decide to use their relationship to strengthen the superhero community. They could host events or training sessions for other heroes. As for their personal relationship, they might travel to places that are special to them, like the location of their first date. This would help them bond again and understand each other better.
The relationship could be stronger in terms of trust. They've both had experiences without each other, and now they'll value the relationship more. They might also start to rely on each other in new ways. Maybe Nightwing will ask Zatanna for help with magical threats more often, and Zatanna will lean on Nightwing for his combat and strategic skills.
Well, they could start by rebuilding trust. Maybe they go on a date to their old favorite place, like that little diner where they used to share milkshakes. Their friends might be skeptical at first, but as they see Beck and Jade being happy together again, they come around. And Jade could finally open up more about her feelings, which was always a bit of an issue before.
It's also possible that Nightwing and Slade end up having a long conversation during the captivity. Slade might try to convince Nightwing to join his side, perhaps by appealing to some sense of justice that he thinks Nightwing is missing. Nightwing, of course, would resist, but this could lead to some interesting character development for both of them as they debate their different ideologies.
In the fanfiction, Nightwing could be used by the Joker as bait to lure Batman into a trap. The Joker might have some elaborate and sadistic plan in store for both of them. Nightwing, being the strong - willed character he is, will likely try to resist the Joker's psychological games and attempts to break him while waiting for rescue.
One way it could happen is through a shared interest. Maybe they both volunteer for an environmental project on the island. Working side by side, they start to remember why they liked each other in the first place. The old sparks begin to fly as they discuss their plans for saving the local wildlife. Trent might play a song on his guitar during a break, and Gwen is reminded of how much she missed his musical side.
One way it could happen is through a shared danger. Maybe a new powerful enemy emerges that threatens Asgard and Earth. Thor and Jane are forced to work together again. As they face this threat side by side, they start to remember all the reasons they fell in love in the first place. The adrenaline of battle and the shared goal of protecting their worlds reignite their passion.
One possibility is that Red Hood has some sort of vendetta against Nightwing. Maybe he blames Nightwing for something that happened in the past, like a mission gone wrong that affected someone close to Red Hood. So he kidnaps Nightwing to get revenge or to make him pay in some way.
One possible plotline could be that they are on a joint mission against a powerful villain. In the heat of the battle, they share a moment of vulnerability and end up kissing. This kiss could be a turning point in their relationship, making them realize their deeper feelings for each other.
A key moment could be when Duncan finally apologizes sincerely to Courtney for all the wrongs he did in the past. This apology could be very emotional and heartfelt, making Courtney see that he has truly grown. Another moment could be when they share a dance at a party. As they sway to the music, they look into each other's eyes and feel the old attraction coming back.
Love and romance are also common themes. Their different personalities - Nightwing's more down - to - earth nature and Zatanna's magical allure - can create a great romantic dynamic. Some fanfictions explore a slow - burn romance between them, starting from a simple friendship or partnership and gradually evolving into something more. Others might jump right into a passionate love story. There are also fanfictions that deal with the challenges of a relationship between a 'normal' hero like Nightwing and a magic - user like Zatanna, such as how they deal with secrets and the different expectations of their respective communities.
