It would change the fanfic's direction completely. The story might shift from a more complex exploration of different moralities and the gray areas of the underworld to a more straightforward, violent tale of survival among a group of killers. Revy herself would also change as a character. She would have to deal with the consequences of killing Rock, which could lead to her becoming even more hardened or, in some cases, having a moment of self - reflection that could change her in unexpected ways.
The dynamic between the other characters would change drastically. For example, Dutch, who has some sort of father - figure relationship with Rock, would be deeply affected. He might turn against Revy, or the whole crew could fall into chaos and disarray. Also, the story's themes of redemption and the struggle between good and evil would be altered. Without Rock, there would be less hope for any of the characters to find a way out of the violent underworld they are in.
Their relationship can be developed through shared danger. For example, if they are in a shoot - out together, Rock could save Revy in a non - traditional way, like using his knowledge of the environment to outwit the enemy instead of using guns. This would make Revy see Rock in a new light.
One possible motive could be that Rock discovers something dangerous or unethical about the underworld operations that Revy is involved in. Maybe he threatens to expose it, and Revy, being a character who often acts on impulse and to protect her own interests, decides to kill him to keep the secret.
I'm not entirely sure as it could be a very specific or even a made - up fan - created concept. It might be a fanfic related to 'Black Lagoon' that involves something about 'rock kills' which could potentially refer to a rock - themed or rock - music - related violent or dangerous element within the fan - written story.
Dialogue is key. Have them have deep conversations during quiet moments on the boat. Rock could ask Revy about her life before coming to Roanapur, and Revy could share some of her experiences, albeit reluctantly at first. This would slowly build a bond between them. Also, small acts of kindness like Rock bringing Revy a coffee in the morning when she's in a bad mood could contribute to the relationship development. It shows that Rock cares about her well - being despite their differences.
One great fanfiction could be 'Revy's Redemption'. It delves into Revy's character, exploring her past traumas and how she might overcome them. It has some really well - written action scenes that are in line with the tone of Black Lagoon.
A common theme is the exploration of their complex relationship. Revy is tough and Rock is more of an ordinary guy in a sense, so the fics often play with how they interact and grow closer. Another theme could be adventure, as they are in the dangerous world of 'Black Lagoon' and fanfics might send them on new and exciting escapades together.
For Rock, the kiss might make him more confident in his relationship with Revy. He could become more assertive in the group and in their missions, no longer just the 'civilian' among them. For Revy, it could soften her tough exterior a bit. She might start to open up more to Rock and show a more vulnerable side, which is a big step in her character development as she has always been so guarded.
Perhaps a fanfic where Rock and Revy get stranded on an island during one of their smuggling runs gone wrong. They have to rely on each other to survive, and in the process, they start to understand each other better. Revy learns more about Rock's ideals and Rock gets a deeper insight into Revy's survival instincts.
Another plot could involve Rock and Revy getting stranded on an uncharted island during one of their jobs. They must rely on each other to survive. Rock uses his wits to find food and water sources, while Revy protects them from any threats. This situation could also lead to a deeper understanding between them.
Common themes in 'Black Lagoon Revy and Rock fanfiction' include the idea of loyalty. Despite their differences, they often show loyalty to each other. There's also the theme of moral ambiguity. Rock has to grapple with his own morals in the immoral world he now inhabits with Revy, and this is often explored in fanfiction.
