Yes, I'm talking to you

"I see by your eagerness and the wonder and hope which your eyes express, my friend, that you expect to be informed of the secret with which I am acquainted... I will not lead you on, unguarded and ardent as I then was, to your destruction and infallible misery." pgs 51-52

One clear benefit of writing a frame story becomes the ability of conveying messages to the audience through the narrator. For instance, since Victor Frankenstein, as the novel's second narrator, relays his story to Walton, he indirectly speaks directly to the audience. As he warns Walton of the indefinite tragedy that will arise if he continues down the same path, Frankenstein also foreshadows much misery to come. This interaction sets both a tone of suspense for the evident unknown and sheer wonder as to how Frankenstein created his "monster."

The frame story set up gives Shelley leeway and the flexibility to utilize different characters as different narrators, offering glimpses from opposing viewpoints. Walton, Frankenstein, and Creature thus far have exposed the readers to the continuous eloquent language but drastically different personalities and objectives.
