If I was writing Fanfiction, I would need a team to help me, that's how bad I am.
Then don't ask me if its LBT. You'll have to find a new[er] helper.
I could give you a few ideas, but that's about it if I wasn't working on a fanfiction write now, and I'm writing it like it is an acutally book more than a fanfiction, I'm putting my brain into overdrive, so it'd be a bad idea asking me.
Anyway, if you are writing a fanfiction, I wish you luck with it. When I write an Farthing Wood fanfiction, what I do is: watch a few episodes of the tv series, and I normally get inspiration to write something different.
Maybe you could watch an LBT movie for inspiration if you need anything for a fanfiction? Watching a movie or tv series before writing a fanfiction about it is the best thing that you can do, it sometimes even helps you come up with OC's of your own, and expand on your character.
Maybe that's why I have more than thirty Farthing Wood OC's. Coming up with names for OC's is the hardest part of writing a fanfiction sometimes, especially if you already have plenty of ideas for a story or chapter, but you don't have any characters to add when you are already using every main character in the movie, tv series or franchise.
Like for my second AOFW fanfiction, I used one of the characters names from the tv series as [partial] inspiration for another. I used the name Ranger to come up with a name for another character called Stranger. I admit the name wasn't very original, but it worked for him only appearing in one story.
