There might be some fanfiction that focuses on a more platonic or non - explicit relationship between Loki and Jane. You could search on fanfiction platforms and look for ones that are rated as general or teen - friendly.
One common theme is the 'opposites attract' concept. Loki, the complex and often mischievous Asgardian, and Jane, the intelligent and curious human scientist, are very different, but that draws them together.
One great Loki and Jane love fanfiction is 'Love Beyond the Realms' on Archive of Our Own. It beautifully weaves their relationship with elements of Asgardian magic and human emotions.
A Loki and Jane pregnancy fanfiction could explore how their different worlds collide during this time. Asgardian customs and Midgardian (Earth) customs would be very different when it comes to pregnancy and childbirth. Loki would have to adapt to Earth's ways, like going to doctor's appointments with Jane. Jane, on the other hand, would have to deal with the fact that her child will be part - Asgardian and all that comes with it, such as potential long life and special abilities.
There might be some fanfictions that focus on their relationship in a more innocent and family - friendly way. For example, some could depict their emotional connection, like how they support each other during battles or in difficult times. They might share tender moments like having deep conversations under the stars, without any inappropriate content.
Well, Loki might be overprotective. He has seen a lot in his long life, and now that Jane is carrying his child, he would not let any harm come to her. He could use his magic to create a protective shield around her at all times. This would also cause some friction between them as Jane might feel a bit suffocated by his overprotectiveness.
Well, cultural exchange is a common theme. Jane gets to experience Asgardian culture through Loki, and Loki gets to understand Midgardian (Earth) ways better. This can lead to some really fun and educational moments in the fanfictions. Another theme is the clash between science and magic. Jane is a scientist, and Loki is a master of magic. Their different worldviews collide and combine in interesting ways. Also, the theme of protection often comes up. Loki wants to protect Jane from various threats, whether they be from Asgardian enemies or from Earth - bound problems, and vice versa.
The theme of how different worlds (Asgard and Earth) react to the pregnancy also comes up often. There are cultural differences and power dynamics at play. The fanfictions may explore how they navigate these differences while preparing for the arrival of their child.
A recurring theme is the blend of two worlds. With Loki being from Asgard and Jane from Midgard, their baby represents a union of these two very different places. Fanfictions often explore how this affects the baby's upbringing, the couple's relationship, and the relationships between the two realms. For example, there could be cultural clashes or new forms of magic and science emerging from this union.
Another theme is the clash of cultures. Since Loki is from Asgard and Jane is human, their different backgrounds play a role in how they approach the pregnancy, like in some fanfics where Asgardian traditions around childbirth are introduced.
