In the story "Apollyon" by Jennifer L. Armentrout, a character named Deacon reveals his concerns about his changing nature by jokingly referring to himself as a "fire bug." His playful comment highlights a struggle with internal conflict and a sense of transformation, yet the humor behind it does not resonate with Aiden, another character who seems more serious or troubled by the implications of Deacon's words.

The interaction underscores the tension between the two characters, suggesting that while Deacon tries to lighten the mood with humor, Aiden is focused on the deeper, more serious consequences of their circumstances. This exchange reflects the broader themes of identity and change present in the book, showcasing how humor can sometimes fail to bridge the gap between different emotional experiences.
