In fanfiction, their relationship development often involves facing external threats together. When they are married, they become a united front against new evils. This makes them rely on each other more, strengthening their bond. Also, they start to share their innermost feelings and secrets, which deepens their relationship on an emotional level. For instance, Spike might share his past traumas with Buffy, and she in turn might open up about her fears as a slayer.
