Their relationship could develop through shared experiences. For instance, if they face a common threat together, like a group of bandits attacking the diner. This would force them to rely on each other and build trust.
The waitress might be the one to help Qrow deal with his inner demons. Since he has a lot of baggage due to his past and his semblance. She could offer him a listening ear and kindness, which gradually turns into a deeper emotional connection.
One good example could be a story where Qrow stumbles into a diner where the waitress works. She initially mistakes him for a regular drunk, but as the story progresses, she realizes there's more to him. Maybe she helps him when he's injured after a Grimm encounter near the diner.
Ruby, on the other hand, would probably see Qrow as not just a mentor but also a friend. She might start looking out for him more, especially if Qrow has any lingering physical or mental wounds from the war. Their relationship could shift from a more teacher - student dynamic to a more equal partnership where they support each other in rebuilding their world.
His character might develop by learning to be more open and communicative. In the RWBY series, Qrow is often a bit of a lone wolf. As a father, he has to break out of that shell. He could start sharing his past experiences and stories with his child, which not only helps the child understand the world better but also deepens their bond.
Well, in many RWBY fanfictions, Qrow and Clover's relationship is complex. Clover's positive and rule - following nature contrasts with Qrow's more jaded and self - reliant self. Sometimes, they start off as just colleagues in the fight against the Grimm, but as the story progresses, there could be a deeper understanding or even a friendship developing between them. Their interactions can also be influenced by the overarching story of the RWBY universe, like the power struggles and the secrets that are being uncovered.
You can also develop their relationship through shared secrets. Maybe the OC discovers something about Glynda's past that no one else knows. Instead of using it against her, the OC keeps it a secret. This act of trust makes Glynda more open to the OC. And then they can start to have deeper conversations, which in turn strengthens their relationship.
The relationship between Qrow and Winter in RWBY fanfics can be quite fascinating. Qrow, being a bit of a rogue figure, might initially view Winter as just another Atlas elite. However, as the story progresses, they could find common ground. Maybe they both realize they are fighting for the same ultimate goal, just in different ways. Winter's cold exterior could start to thaw in the presence of Qrow's more easy - going personality, leading to some unexpected alliances or at least a better understanding between the two characters.
If Qrow was gender - swapped, her personality could have a different kind of charm. She might use her femininity in a way to manipulate situations to her advantage, but also be more empathetic. For example, she could be more patient when dealing with the younger characters, understanding their struggles on a deeper level. And instead of the gruff exterior the male Qrow has at times, she could have a more approachable and warm exterior while still being a tough fighter.
First, study the characters well. Know their personalities, backstories, and relationships in the original RWBY series. For example, Qrow is a bit of a loner with a drinking problem but is also very loyal. Amber was a Fall Maiden, so her powers are important. Autumn might be a more mysterious character if not much is known about her. Then, create a unique plot that involves all of them. It could be a quest, a mystery, or a character - driven drama.
There would also be a shift in their dynamic. Instead of just being an acquaintance or someone she looks up to in a way, he would become a parental figure. This could lead to some interesting conversations. For example, Qrow might start giving Weiss advice not just on fighting but also on life and how to deal with her family issues. He could share his own experiences growing up and how to handle the pressure of being part of a powerful family like the Schnees.
In the fanfiction, Ruby and Blake's relationship might develop as they discover new things about each other in Volume 5. Maybe they find out they both have a secret hobby or interest. This new knowledge could bring them closer. Also, if one of them gets injured, the other could take care of them, which would strengthen their bond. For instance, if Blake gets hurt, Ruby could use her leadership skills to ensure Blake's safety and recovery, and this would show Blake how much Ruby cares about her. As a result, their friendship would deepen.
