The scene emphasizes a sense of foreboding as Dan observes the eyeless sockets of skeletons, drawing his attention to the macabre allure of collecting something as dark as human bones.

However, Amy quickly intervenes, reminding Dan that such a collection is inappropriate and not something they can pursue. This exchange highlights the dynamic between the siblings, with Dan's curiosity clashing against Amy's sense of morality and practicality as they face the challenges of their adventure.
