Hello my name is Talulah, heya!
I realised a while ago that writing an episode story is much easier when you really plan things out bit by bit. I also recently made a thread on cliches and realised a lot of them could be changed if new writers were taught how to plan a story from the beginning. It can also limit the amount of stories that are cancelled. Anyway I built a thick story planner from scratch on google presentations. You can download the planner into a powerpoint, pdf, odp and more. This way you will have a clear representation of what you’re writing and it’s organised to help you build the story from the foundations up. Starting with a rough idea into a fully flushed exciting story that anyone will want to read. I hope it helps, if you have any questions feel free to ask just PM me and I’ll respond within a couple days I should think.
P.s. I’ve been reading episode for 5 years and writing too. I added notes all over the planner to help guide you away from cliches and flush out your story more, I really suggest you read them for the full effect and guidance.
