I like dialog; it's usually the first part of a scene that comes to me. When it's clicking, I can hear those voices in my head
About introspection, I was thinking... I was taught in school that drama is all about conflict -- man vs. nature, man vs. man, or man vs. self. And introspection can be a scene of internal conflict, where the character thrashes out an issue and decides to change something. It's not always that, of course, but quite often it is.
