Should we start another dialogue in the novel?
Whether the dialogue in the novel needed to be re-written or not usually depended on the nature and situation of the dialogue. If the dialogue is an exchange between characters in an independent story, you can add another paragraph between the dialogue to increase the cohesiveness and legibility of the story. This would allow the readers to better understand the dialogue between the characters and the development of the plot. However, if the dialogue is part of a plot, such as dialogue between characters, background introduction, or narrative language, then the dialogue can be used directly as part of the story without the need for another paragraph. In writing a novel, you should try your best to use dialogue to show the character's personality, emotions, and thinking process so that the reader can better understand the plot and the relationship between the characters. Therefore, they could decide whether or not to start another conversation based on the specific situation.
