A plot could involve a cultural exchange in their wedding. Since Scott has his own pack and cultural background, and Allison comes from a family of hunters, they could incorporate elements from both worlds into their wedding. For example, the werewolf pack could have some special rituals during the ceremony, and Allison's family could bring in some hunting - related traditions in a more symbolic way. This would show how they are bringing two very different worlds together through their marriage.
Scott could become more confident and stable. Marriage often brings a sense of responsibility, and for Scott, it might mean he becomes more of a leader not just in his pack but also in his family life. He might be more decisive and less impulsive. For Allison, she could become more empathetic. Being married to Scott, she'll be more involved in the werewolf world and will need to understand the pack members better. This could lead to her being more open - minded towards supernaturals in general.
