Friendship is often a common theme. They might explore how Morag and Brighid become friends, what they learn from each other, and how their friendship grows. Another theme could be adventure, if they are characters in a game or story with an adventure - based plot.
I'm not sure of a specific one off the top of my head. But you can try looking on fanfic websites like Archive of Our Own. There are often many fan - created stories for various pairings, and you might find some great Morag x Brighid fanfic there.
Maybe they stumbled upon it by accident. For example, they could have been searching for something related to a favorite book or movie and came across fanfiction websites.
The story is likely about Katie Morag and something to do with a new pier. Maybe she has adventures around it, or it could be about how the new pier affects her island life.
One common theme could be the exploration of unexpected relationships. Since mpreg is involved, it often delves into how the characters deal with the non - traditional situation of male pregnancy. For example, how the relationship between Harry and Draco might change due to this new development with Zeke in the mix.
Pulp Fiction is a complex and iconic movie with a lot of memorable characters. However, Zeke and Zeb are not characters that are typically associated with it. It's possible that there is some sort of misinformation or a very niche interpretation where these names are related, but in the general understanding of the movie, they don't exist within its world.
