A plot twist could be that Jasper has a pre - wedding vision (if he has some sort of precognitive ability in the fanfiction) that shows a disastrous future if they get married. So he has to decide whether to go through with it or not. Or perhaps Bella is turned into a vampire just before the wedding in an unexpected way, like being attacked by a rogue vampire, and she has to quickly adapt to her new state and decide if she still wants to marry Jasper as a vampire.
One possible plot twist could be that a long - lost relative of Bella shows up and tries to stop the wedding because they have some dark secret about the Cullens. Another could be that a new vampire coven arrives and challenges the Cullens right before the wedding, forcing Bella and Jasper to postpone it while they deal with the threat. Maybe there's also a twist where Bella discovers a new power within herself on her wedding day that changes the whole dynamic of the relationship with Jasper and the Cullen family.
Well, it could be that the Volturi find out about the wedding and come to Forks. They claim that the marriage between Bella and Jasper violates some ancient vampire law. This would put the Cullens in a difficult situation as they have to either fight the Volturi or find a way to prove that their marriage is acceptable. It would add a lot of drama and tension to the fanfiction story.
