First, this is a group of good, strong ideas and they can be developed into something beautifully entertaining. Is Dr Sarah Chen the central character, or is Webb/APEX the central character? There’s a couple of different ways I can help suggest depending on which way you want to lean. Or do they share the spotlight? Second, I need to help you decide what the ultimate goal is, so we know essentially what you feel like the ending should be. We can fill in the rest from there and help you decide if these are truly separate chapters that need expanded upon, or if they’re ideas that belong to the first chapter and need to be left alone or worked in differently.
