Minecraft wiki entry for dialogue, associated text: Dialogue can be branched with the use of a scene file. The scene file is a json file located inside the dialogue folder in the root directory of the active behavior pack (%localappdata%\Packages\Microsoft.MinecraftUWP_8wekyb3d8bbwe\LocalState\games\com.mojang\development_behavior_packs\<your behavior pack folder>) that contains all the information needed for branching dialogue. There is no limit to the amount of scene files, as the game will read all the files in the folder and call based on scene_tag property indicated in the given scene data.
