Character A is monologuing a bit, and I want to break it up with some of character B's reactions. Question is, do I break the quotation with a simple comma, insert the reaction, comma and back to the quotation, or should I interject the reaction in its own paragraph. Not directly from the story, paraphrased for functionality: Or Or C) Something else. It didn't look right when I first typed it, and now I've stared at the options so long that none of them look right. Or wrong. Ugh.
