There are many times when we are writing our stories that we have a big scene where a major event takes place between the characters. Does the scene shine in its execution, or fall flat? I myself find when I am rewriting a draft this can occur, and that a scene which should be prominent, adding to the action, and opening up other story possibilities, does not deliver this, but, this can be remedied very easily. The reactions of characters to an event in the story, or to each other, can add depth, and reveal more about the characters than we originally envisioned.
This is something, though, that should be picked up in subsequent edits after the first draft, when we are perusing the story cafefully for any inconsistencies or deficiencies. I believe the main key is that we put ourselves in the position of our characters, and think what they would do in these situations. Sometimes having a character not react to a situation immediately, or having this delayed for plot purposes, is also useful, but, in any which way, if it is true to the character and story, then all the better. What are your thoughts on this?
