In a story, they could be involved in a local community project in Ooo. Maybe they help build a new playground for the Candy People. Working side by side, they discover new things about each other. Marceline might learn that Jake has a hidden talent for building, and Jake might find out that Marceline is really good at motivating others. This would lead to a more profound understanding and a closer friendship.
They could go on a long - distance journey together. Along the way, they face various hardships like running out of food or getting lost. Through these experiences, they learn to rely on each other more. Jake might use his body to shelter Marceline from a storm, and Marceline could use her vampire powers to find their way in the dark. This would not only strengthen their friendship but also show their loyalty to one another.
Their friendship could be developed by having them share secrets. For instance, Marceline could tell Jake about a time she was really scared as a vampire. Jake, in turn, could share his fears about losing his family. This would deepen their bond.
Another way is through music. Since Marceline is a talented musician, she could teach Ice King how to play an instrument. This shared activity would be a fun way for them to bond. As they practice together, they would get to know each other better on a more personal level. It could also lead to them creating their own unique music that reflects their relationship and experiences.
In fanfiction, their relationship could be developed by having them teach each other things. Finn could teach Marceline about his simple but effective survival skills, like building shelters or finding fresh water. Marceline, on the other hand, could teach Finn more about the complex magic that exists in the Land of Ooo. This exchange of knowledge would not only bring them closer but also make them respect each other more. Also, they could get into some light - hearted arguments about different ways of doing things, which would then lead to a better understanding of each other's personalities.
Their relationship could be developed through music. Marceline could teach PB how to play the guitar, and in the process, they open up to each other about their past traumas. PB might share her insecurities about ruling the Candy Kingdom, and Marceline could talk about her loneliness as a vampire.
Their friendship can be developed by having them share their deepest secrets. For example, Max could tell Eleven about her family issues, and Eleven could open up about her past in the lab. This would create a stronger bond between them.
One interesting plot idea could be Jake and Marceline teaming up to explore a new, mysterious part of the Land of Ooo. Maybe they find an ancient relic that has the power to change the world. Another idea is that they get caught in a time - loop and have to figure out how to break it while dealing with their own personal issues.
One way to develop their friendship is through facing challenges together. Let's say a big storm hits their area. They have to work together to find shelter for all the small creatures. During this time, they rely on each other's strengths. Littlefoot's knowledge of the land and Ali's agility help them succeed. This shared experience would strengthen their friendship. Also, they could have little arguments along the way, like about which direction to go, but then learn to respect each other's opinions and grow closer because of it.
Their characters could be developed by putting them in challenging social situations. Maybe they attend a high - society medical event together. Addison, being used to such events, could help Jake navigate through it. Jake, on the other hand, could introduce Addison to a different side of the medical community. Through these interactions, their personalities would shine and develop further.
They could face a really tough situation together, like being stuck in a game world where they have no powers. They'd have to rely on each other's wits and personalities. Ralph could use his big - heartedness and Vanellope her cleverness to get out. This would deepen their bond as they see new sides of each other.
One way is by having them go through a really tough trial together, like being wrongly accused of a crime in Auradon. They would have to prove their innocence and during this process, they would rely on their trust in each other. Their friendship would deepen as they see how far they are willing to go for one another.
Their friendship can be developed by having them face a really tough challenge together. For example, if they are trapped in a dangerous magical maze. They would have to rely on each other's strengths. Lucy's intelligence and Aquarius' power could be combined to find a way out. This would deepen their bond.
