Adventure is another theme. Since they travel through time and space together, many fanfics have them going on all sorts of exciting adventures, whether it's saving a planet or exploring a new era. It adds to the overall charm of their relationship as they face these challenges together.
Separation and longing are also common. Given their story in the original series, fanfiction often plays with the idea of them being separated and how they long for each other. This can create some really heart - wrenching and beautiful stories as they try to find their way back to each other.
One popular theme is the adventure aspect. Fans often write about the baby growing up in a world full of time - traveling and alien encounters, just like the Doctor and Rose had. Another theme is family. It could be about how the Doctor, Rose, and their baby form a unique family unit, dealing with the challenges of being part of different species. Also, the theme of protecting the baby from various threats, both from within their own universe and from other dimensions, is quite common in these fanfictions.
A great idea for this fanfiction could be that Rose starts having dreams about their future child. These dreams could give them clues about the baby's purpose or the challenges they will face. The Doctor would be very interested in these dreams and try to analyze them scientifically.
In these fanfictions, a frequent theme is time - related chaos. Since they are both time - traveling Doctors, they might accidentally disrupt the time - space continuum and have to fix it together. There's also the theme of self - discovery. As they interact, they might learn new things about themselves. For instance, the Tenth Doctor could learn to be more carefree from the Eleventh Doctor, and the Eleventh Doctor could learn about the importance of taking things seriously from the Tenth Doctor. Additionally, the theme of nostalgia can be present. The Tenth Doctor might remember his past adventures, and the Eleventh Doctor could be intrigued by them.
In the fanfiction, Rose's pregnancy could be a catalyst for the Doctor to finally settle down in one place for a while. Maybe they find a peaceful planet where they can build a home and prepare for the arrival of the baby. Their friends from their adventures might come to visit and offer their support. It could also lead to some interesting cultural clashes as they combine their different upbringings and knowledge to raise the child.
Love and friendship are common themes. Their relationship is often explored in terms of how they care for each other deeply. Another theme is adventure.

Love is a common theme. The doctor and Rose may fall in love during the course of the story. Another theme is healing. The doctor's skills are used to heal Rose both physically and emotionally.
Another theme is the insecurities within their relationship. Despite their strong bond, both characters have their insecurities. Rose might feel insecure about not being as intelligent as some of the Doctor's other companions, and this can fuel her jealousy. The Doctor, on the other hand, might be insecure about his ability to truly love and be loved, which can make him react jealously when Rose shows interest in someone else. It's all about exploring these hidden aspects of their relationship through the lens of jealousy.
