A great way to make character interactions in a Gravity Falls Reverse Falls crossover fanfiction engaging is to explore their relationships. Maybe there's a family connection that's different in each world. For instance, Mabel and her Reverse Falls counterpart might initially dislike each other because they're so different, but as they face challenges together, they start to understand and respect each other. You can also play with cultural differences between the two worlds. If Gravity Falls has a certain set of values and Reverse Falls has a different, almost opposite set, how do the characters react to those differences? This can create a lot of tension and also opportunities for growth and change in the characters.
To create a compelling character interaction, think about the goals of the characters. In a crossover, a character from Gravity Falls might be trying to save their world, while a Reverse Falls character could be trying to take over the other world. When they meet, there will be conflict and negotiation. Let their different motives drive the conversation and actions. Also, use their unique abilities or powers in the interaction. If one can read minds and the other can manipulate shadows, how do those abilities play off each other when they interact? It can lead to really interesting scenes.
