They start to learn from each other along the way, with Hermione teaching the Doctor some basic spells and the Doctor showing Hermione the wonders of the universe outside her own world.

One idea could be that the reader is a time - traveler from the future who has come back in time to prevent a great disaster that the 11th doctor is unknowingly about to cause. This would create a lot of tension and mystery as they both try to figure out what's really going on.
A more emotional plot could be that Clara discovers she's pregnant and is initially scared about how the Doctor will react. She's worried he'll leave because he's always been so independent and on the move. But the Doctor surprises her by being overjoyed and they start preparing for a life together with the baby, facing all the challenges that come with it.

One plot idea could be Naruto facing a new threat from an old enemy who has found a way to return stronger. For example, Orochimaru could have created a new form of jutsu that allows him to possess multiple shinobi at once and Naruto has to figure out how to stop him without harming the innocent. Another idea is Naruto dealing with political unrest within the Hidden Leaf. Some clans might not be happy with his new policies regarding ninja training and he has to find a way to keep the peace. A third idea could be Naruto going on a diplomatic mission to a far - off land where they have a very different view on ninjas and he has to convince them that the Hidden Leaf means no harm.
Perhaps the 8th Hokage has to deal with internal political unrest within the Hidden Villages. Some ninjas might be unhappy with the new leadership and try to undermine the 8th Hokage's authority, leading to a complex web of intrigue and conflict.
