And there could be a sub - plot about Harry being excited to become a big brother and learning how to protect his future sibling.
Another plot could be that there are some magical complications with the pregnancy. The healers in the wizarding world are stumped, and Lily has to seek out ancient magic or long - forgotten spells to ensure the health of her unborn child. Along the way, she discovers secrets about her own family's magic that she never knew before.
The Hogwarts faculty would also have a reaction. Professors like Dumbledore would be keeping a close eye on the situation. He might be thinking about how this new child could potentially play a role in the future of the wizarding world. And the other professors might be sending gifts or well - wishes, while also being a bit apprehensive about what it means for the balance of magic in the community.
