In the excerpt from "Pure" by Jennifer L. Armentrout, the narrator is perplexed about a fading blue tattoo on their palm that remains visible despite attempts to make it disappear. This tattoo represents a lingering reminder of their past experiences, prompting questions about its significance and persistence over time. The frustration with its presence illustrates a deeper struggle with identity and memory.

Seth's reaction emphasizes the futility of trying to erase the past, as he advises against shaking the hand like an Etch-A-Sketch hoping to reset it. This interaction highlights both the bond between characters and the theme of dealing with persistent elements in their lives, suggesting that certain marks, whether physical or metaphorical, are meant to stay and shape who they are.
