In Darren Shan's novel "Wolf Island," a conversation takes place that suggests an internal struggle with one's sanity. One character makes a light-hearted comment about the possibility of going insane, but the exchange reveals a deeper, more serious sentiment underneath the humor. Kernel, acknowledging the remark, shows that he is aware of the gravity of the situation they are facing, even if he tries to mask it with joking.

This dialogue highlights the tension between humor and reality, illustrating how people cope with difficult circumstances. The shift from jest to a more somber acknowledgment implies a profound disquiet that characters experience as they navigate their challenges on Wolf Island. Both humor and candor in this exchange serve to portray the complexities of human emotions in the face of adversity.
