Maybe a plot where the pregnancy pact was made as a form of rebellion against the strict vampire or werewolf rules in the Twilight universe. They then have to face the consequences and find new ways to co - exist. This could involve trying to protect their unborn children from the various threats in their world.
One interesting storyline could be about how the characters deal with the social and family pressures that come with the pregnancy pact. They might struggle to balance school, friendships, and their newfound situation.
One interesting plot idea could be exploring how different characters adapt to the post - apocalyptic world in new and unexpected ways. For example, a character who was once a timid office worker becomes a fearless scavenger.
