But then they realize that it's just their fears getting the best of them, and it actually strengthens their resolve to have a perfect wedding. This can also show the support of their friends and family as they help the character through their doubts.
One idea could be a long - lost relative showing up at the wedding and causing chaos. Maybe they claim to have a right to some family heirloom that was supposed to be part of the wedding decor.

One idea could be a wedding between a wizard from Gryffindor and a witch from Slytherin, which could cause a stir among the Hogwarts alumni.

One idea could be that Merlin has to hide his magic even on his wedding day to Arthur.

One idea could be that they face a series of challenges while planning their wedding. For example, they might have trouble finding a venue that suits both their spooky and sweet natures. Maybe the place they initially choose gets haunted by a more malicious spirit who doesn't want them to get married there. Another plot could involve their families and friends coming together. Sally's rag - doll friends could be helping her with her wedding dress, while Jack's skeleton crew could be in charge of the music and entertainment. They could also have a unique wedding ceremony that combines elements of both the Halloween Town and Christmas Town traditions.
Well, perhaps in the fanfiction, Serena could design her own wedding dress inspired by her Pokemon performances.

A great plot for Harry and Hermione's wedding fanfiction could be that they face some sort of dark magic threat right before the wedding.

For the actual wedding, Hermione could wear a dress that has some magical properties, like changing colors to match her mood, and Harry could have a special wand that he uses to create a unique display of magic during the ceremony.
