To develop both characters, you can put them in situations that force them to rely on each other. For instance, if they get lost in a strange part of town. Huey would use his street smarts and Jazmine her charm to get help. Through this, they would see new sides of each other. Huey might see Jazmine's determination and Jazmine might see Huey's protective side. This would deepen their relationship and also develop their individual characters.
For Huey, you can focus on his intellectual side more. Have him spout out facts and historical references during his interactions with Jazmine. For Jazmine, emphasize her dreams and her somewhat naive view of the world. Show how Huey's practicality contrasts with her idealism.
Their relationship would likely become more serious. They would have to rely on each other more, especially as they prepare for the baby. There would be a new level of intimacy as they share the experience of pregnancy.
For Huey, his character could be developed by showing his softer side more. Maybe when he's with Jazmine, he lets his guard down a bit and shows his sense of humor. He could also grow in his ability to communicate his complex ideas more simply. For Jazmine, she could develop by becoming more independent in her thinking. Instead of always following the mainstream, she starts to question things more like Huey does.
