One scenario could be at a party or gathering in the Sly Cooper universe. If Sly is dancing with or chatting up another girl, Carmelita will likely get jealous. Another is when Sly has to go on a mission with a female partner and Carmelita isn't involved. She might start to feel left out and jealous. And sometimes, if there's a female character who is overly friendly with Sly, like constantly complimenting him, Carmelita will get jealous.
A common scenario is when Sly is teamed up with a new female thief. Carmelita would see them working closely together and get jealous.
Well, in Sly Cooper fanfiction, a typical scenario for Carmelita's jealousy is when Sly is training a new female recruit. Since they have to spend a lot of time together during the training process, Carmelita might start to feel that this new girl is getting too close to Sly. Another scenario is when Sly is rescued by a female character. Carmelita might feel that she should be the one to rescue Sly all the time, and seeing another girl in that role can make her jealous. Also, if there's a female inventor or strategist who works closely with Sly on a new project, Carmelita could get jealous of their intellectual connection.
Perhaps Carmelita is investigating a lead on a major crime syndicate alone, against Sly's advice. She gets ambushed and hurt. Sly then has to infiltrate the syndicate's hideout to get the medicine or information needed to heal her. Along the way, he discovers some secrets about the syndicate that also relate to his family's past, adding more depth to the story.
It could also be a key to a locked area that holds important information. Maybe it's the key to a room in a museum or a secret lair where there are clues about Sly's family history. Carmelita might have unknowingly had this key, and Sly getting it from her could be a major turning point in his quest for knowledge about his past.
One common theme is the struggle between their two worlds. Sly being a thief and Carmelita being a law enforcer. Their love has to overcome this huge obstacle.
A fanfiction of Sly Cooper and Carmelita getting married could be full of twists and turns. For example, just as they are about to say their vows, one of Sly's old foes could show up with a plan to disrupt the wedding. But Sly and Carmelita, being the strong characters they are, team up to defeat the foe and then continue with their wedding. Their relationship has always been complex, with Carmelita chasing Sly in the past. Now, as they get married, it symbolizes a new chapter where they are on the same side, facing the future together, and their love overcomes all the past differences and challenges.
One common theme is the idea of redemption. Since Sly is a thief and Carmelita is a cop, sometimes fanfictions explore how Sly might redeem himself in Carmelita's eyes. Another theme is forbidden love, as their different standings in society make their relationship a bit of a taboo in the context of the story world.
The theme of family also pops up. Sly has his own family history and Carmelita has her own set of values influenced by her family or her role as a law enforcer. In fanfiction, their different family backgrounds can be used to create conflict or to bring them closer together. For example, Sly's family of thieves might be at odds with Carmelita's sense of justice, but they could also find common ground through understanding each other's family values.
One common theme is the 'forbidden love' aspect. Since they are often on opposite sides in the game, their love in fanfiction can be seen as something that goes against the norm of their world. Another theme is redemption, like Carmelita seeing Sly in a new light and him trying to change for her.
One of the main themes is the struggle between duty and love. Carmelita has a duty to uphold the law, but she's falling for Sly. And for Sly, he has to decide if he's willing to give up his life of crime for Carmelita. Also, the theme of trust is big. They have to learn to trust each other despite their differences.
After Carmelita gets hurt, Sly might become more protective of her. This could lead to a softening of their adversarial relationship. He could start to see her more as a person in need of protection rather than just an enemy chasing him. For example, he might bring her food or keep watch over her while she recovers.
Adventure is also a big theme. They often go on adventures together in the fanfics. Maybe they team up to stop a bigger villain that threatens both of them. This combines the action - packed nature of the Sly Cooper games with the relationship aspect between the two characters.
