Maybe Bilbo is known for writing a lot of fictional stories, so he got the 'scribe' part, and 'fanfic' might imply that his stories are related to some pre - existing works or fandoms in a way.
One possibility is that Bilbo has a habit of documenting his adventures in a rather fictionalized way. His writings could be seen as a form of fanfic because they might be inspired by the events and characters he encounters. Since he is constantly writing these accounts (hence'scribe'), and they have a fanfic - like quality to them, perhaps due to his creative interpretations or added fictional elements, he has been nicknamed scribe fanfic.
Well, if we take the given information at face value, Bilbo is the one with the nickname scribe fanfic. It's not clear from just this statement why he has such a nickname, but it could be something related to his character's penchant for writing or documenting things in a fictional context, perhaps in a story or saga where he is involved in some sort of fan - created lore that has earned him this moniker.
One possible plot is that Dwalin and Bilbo are on a journey and they need to cook to survive. Dwalin has his dwarf recipes in mind, but Bilbo is skeptical. They first have to find the ingredients in the wild. Bilbo uses his knowledge of the land to find things like wild berries and mushrooms, while Dwalin hunts for small game. When they start cooking, they learn from each other. Dwalin teaches Bilbo how to cook the game in a dwarf - style stew, and Bilbo shows Dwalin how to make a delicious berry tart. Their relationship grows stronger through this cooking experience.
In this fanfic, perhaps Bilbo, who might be an orphan or in a difficult situation, is taken in by the Dwarves. The Dwarves could see his potential, like his cleverness or his ability to think on his feet. They might raise him as one of their own, teaching him Dwarvish culture, combat skills, and the value of loyalty within their community. This could lead to Bilbo growing up with a different set of values and skills compared to his original upbringing in the Shire, and it could also set him on a different kind of adventure, one more intertwined with Dwarvish affairs.
Well, perhaps the fanfic could be about Bilbo using the gems he acquired during his adventures to adorn himself in a show of newfound wealth and status. Maybe he wears them to a grand event in Middle - earth, causing quite a stir among the other characters.
Well, perhaps Bilbo uses his wits and the One Ring to get the upper hand on Azog. He could set a trap using his knowledge of the terrain and the orc's weaknesses.
One possible plot could be that Bilbo discovers a magical artifact during his adventures that has the unforeseen consequence of causing Orcs to rapidly grow in size and strength. This throws Middle - earth into chaos as the Orcs become more formidable foes. Bilbo then feels responsible and embarks on a new quest to find a way to reverse this effect.
Well, perhaps the plot could involve Bilbo hiding her true gender identity in a world where being a girl might bring unexpected challenges or opportunities. Maybe she has to keep it a secret to be able to go on adventures like the male hobbits do. She could be constantly worried about being discovered while also having to deal with her own self - discovery and acceptance of her femininity.
One possible consequence could be that Bilbo's injury makes him more cautious in his future adventures. He might be slower to trust or more aware of potential dangers around every corner.
There could be the company's CEO, who might be initially hesitant about adopting Bilbo but later sees his potential. Another character could be Bilbo's mentor in the company, someone who helps him understand how things work.
Maybe she just wanted to have some fun. Sisters can be quite mischievous sometimes and dressing you as a girl might seem like a hilarious idea to her.
