One way is by exploring their similarities. Both Blossom and Brick are leaders in their respective groups. By highlighting how they lead, make decisions, and deal with pressure, they can find common ground. They might start respecting each other more and this respect can turn into a deeper connection. Also, a situation where they have to protect each other's loved ones could be a turning point in their relationship.
Another way to develop their relationship is through a series of misunderstandings that are eventually cleared up. For instance, Brick might be seen doing something that Blossom misinterprets as an act of kindness, when in reality it was for his own self - interest. But as the truth unfolds, they learn more about each other's motives and personalities. This back - and - forth of misjudgment and understanding can add depth to their relationship.
