A plot hole is a gap or inconsistency in a storyline that contradicts the flow of logic provided by the plot. Plot holes are frequently unintended, either as a consequence of editing or the writer just forgetting that a new event would contradict prior ones.
Mila doesn't know why suddenly the strange being is claiming to be the plot hole of the novel they are in.
"Plot hole? You say you're a plot hole?"
Mila stopped massaging her temples and looked at the strange being blankly. The strange being's appearance supported how she claimed she was the plot hole.
From its unknown name and peculiar body structure, it seems the author didn't even write anything about the strange being's physical description at the time it appeared as only a genderless mannequin-like being.
Mila was reviewing what she knew about the novel and her previous world while the strange being didn't show her surprise at what she had read in Mila's mind.
