A major theme is the power of knowledge. Since the time traveler has knowledge of future events, they use it to their advantage to fix things. Also, the theme of fate versus free will is often explored. Some stories show that despite the time traveler's efforts to change things, fate still has a way of working things out in a similar way, while others show that free will can completely rewrite the future. In addition, the idea of self - discovery is common as characters often learn more about themselves when they go back and face their past.

The idea of time travel as a form of spiritual journey could be explored. In the Hobbit universe, time travel might not just be about physically moving through time but also about the hobbits connecting with their ancestors on a deeper, spiritual level. For example, a hobbit could travel back in time and meet an ancient hobbit sage who imparts wisdom that is crucial for the future of the Shire. This would blend the fantastical element of time travel with the rich cultural and spiritual aspects of the hobbits' world.
One way to improve the plot could be by making the time travel rules more consistent. For example, if the hobbits can travel back in time, clearly define the limitations and consequences of such travel. This would add depth to the story and prevent plot holes.
