 is creating something we call Big Sheets, which is a sort of scene-by-scene breakdown of each episode and each storyline. So a linear breakdown of each storyline and then a linear breakdown of each episode, sort of working out how all the storylines best weave together and where all the various characters are going to, arcs are going to end up. You've got that. Some writers do it on post-it notes and cover walls with different colour post-it notes.
