Trako A good way to do that would be to have two character's go back and forth for an extended period and have someone interrupt later on to allow the story to flow more. Example:
X said, "..."
Y replied, "..."
"..."
"..."
"..."
"..."
Z interjected "Alright you two, let's not argue, what if we ...?"
"I concur," A agreed.
Something like that.
