Well, a popular plotline is the exploration of their different powers. Frisk has their unique abilities and Betty has hers. In some fanfictions, they end up teaching each other about their powers. Also, there could be a plot where Frisk and Betty are from different timelines that somehow merge. This creates a lot of tension and also opportunities for their relationship to grow as they navigate this new, chaotic situation.
