I'm telling a story in third-person objective, the first part being basically an objective description of events around a certain character. I got to a brief action scene, and it fell flat. What the character does is of interest to the progression of the story, but the more interesting stuff (I think) is her decision-making and brief thinking and emotions.
Only the first part of the story will be about this character. There will be later scenes where she is not present, including one where the characters involved will be dead at the end of the scene.
So, how do I present thoughts and emotions in an action scene in third-person objective? Or should I switch to a more personal third-person viewpoint (I'm not above rewriting everything I've written in another viewpoint)?
