Let me explain:
An episodic plot is one that is divided into distinct episodes or segments, each of which tells a self-contained story. In contrast, Frankenstein has a continuous plot that follows the development of the main characters and the consequences of their actions. While the novel can be divided into different sections, such as the creation of the monster, the monster's encounter with the De Lacey family, and the pursuit by Victor Frankenstein, these sections are all interconnected and contribute to the overall narrative. Therefore, the plot of Frankenstein is not episodic.
