Jay’s second-hand diving gear is a symbol for his fraught inheritance from his father. The equipment is old, damaged, and conspicuously lacking in modern technology, representing the burdensome and dangerous aspects of the legacy that Jay has received. The rough, scarred, imperfect gear becomes a physical manifestation of Mitt’s harsh, outdated worldview, a legacy that is both essential for survival in his father’s world and a constant source of peril to Jay’s psychological well-being. This connection is established early when Jay reflects that putting on the gear is like carrying “seventeen years of being Mitt Gardiner’s son, the expectations and disappointments, all of it on his back one more time” (17). The faulty wetsuit zipper and the improvised battery weights highlight the flawed and precarious nature of this dubious inheritance even as the early references to the cheap, risky “suicide clip” (19) ironically emphasize the manner of Mitt’s death. This specific clip, a symbol of makeshift carelessness, snags on the giant squid’s tentacle and seals Jay’s fate, demonstrating that the flaws in his father’s legacy are precisely what force him into a life-or-death reckoning that he might otherwise have avoided.

Once Jay is trapped inside the whale, the meaning of the diving gear shifts, embodying The Bitter Lessons of a Father’s Harsh Love. The same flawed inheritance that endangered Jay now becomes his only means of survival, as when he uses a fin to brace the stomach walls and prevent himself from being crushed by the flesh of a whale that has become synonymous with Mitt himself. Thus, Jay’s survival depends on his willingness to adapt his father’s lessons to fit his current situation. This transformation shows that even a painful, damaging inheritance contains necessary tools for survival. Jay’s ultimate triumph lies in mastering his father’s various lessons and gifts in order to forge his own path out of the darkness.
