Perhaps a prophecy is revealed during Nala's pregnancy. It could be that their unborn cubs are destined for something great, like uniting all the animal kingdoms in the area. This would put a huge responsibility on Simba and Nala, and they would have to start preparing their cubs from the very beginning, changing the way they raise them and the values they instill in them.
One possible plot twist could be that there are difficulties during the pregnancy. Maybe there's a shortage of food in the pride lands which causes stress and potential problems for Nala. This could lead to Simba having to go on a dangerous journey to find a new source of food and ensure the survival of his family.
One common theme is the celebration of new life. The pride would be excited about the new cubs. Another theme could be protection. Simba and Nala would need to protect Nala during her pregnancy and then the cubs when they are born.
It could be about their adventures as young lions. Maybe they explore a new part of the Pride Lands together, facing some challenges like crossing a dangerous river or dealing with a tricky animal that tries to mislead them.
One possible plot could be that after Simba reclaims his throne, he and Nala start to focus on building their family. They could face some challenges like ensuring the safety of their future cubs from remaining threats in the Pride Lands. Nala might also have her own concerns about being a mother, and Simba would be there to support her. They would share tender moments and work together to prepare a safe and loving environment for their new family.
Well, a story could focus on Simba and Nala's journey during Nala's pregnancy. They could face challenges like finding enough food for Nala to ensure the healthy growth of the cubs. And also, they might have to deal with the anticipation and nervousness that comes with expecting new life in the pride.
One possible plot twist could be that the father of the baby is not who everyone initially thinks. Maybe there's a secret admirer or an old acquaintance who turns out to be the father. Another plot twist could be related to the safety of the pregnancy. For example, there could be a new threat in the world she lives in that specifically targets pregnant women. Or perhaps, Michonne discovers some special powers or abilities that are awakened during her pregnancy, which is completely unexpected and changes the course of the story.

Another plot twist might be related to Elizabeth's memories. Since she has had multiple reincarnations, there could be something in her past memories that affects the pregnancy.

A plot twist could be that an enemy from their past resurfaces because they hear about the pregnancy.
