Nightmare Fuel / Jack The Grey Reef Shark

• Though this scene is Played for Laughs, when Jack first sets off on his journey, he is all alone with nothing but darkness everywhere he looks. And if that wasn't nerve-wracking enough, his electroreception means he can pick up every little thing moving through that darkness and he has no idea what any of it is. And since he was just recently wounded by the sailfish, the scent of his blood could easily attract larger sharks.
• Shark-finning is a gruesome and disturbing practice. To put it in perspective: Imagine if an alien abducted you, cut off your arms and legs and then discarded the rest of your body, where you either bleed out or become food for another predator while you lay there helpless. That is basically what finned sharks go through, such as Karen. All the while, everyone, including Tyler, watches in horror. No child should ever have to witness their mother’s death at such a young age, let alone in such a gruesome way.
• Like Karen, Ken’s death isn’t just sad, it’s also extremely unsettling. The pain from the harpoon is so intense that he is sent into a state of shock, and all we see of him is a blank stare as Jack and Jay desperately try to save him.
• When it comes to killing other sharks, Ben does not discriminate. Hell, the only reason he chose Sage as one of his victims was because he was within range while Ben was trying to get his point across about listening to his advice. That could have easily been anyone else in the school who was simply in the wrong place at the wrong time. Another one of his victims is a hapless mako shark whom he killed just so he could steal the mako’s sailfish and present it as his own catch. It just goes to show just how merciless Ben really is.
• The sad truth is that the threats Jack faces in the story are very real threats that sharks face in real life, and since sharks are considered apex predators, they are one of the most vital parts of the ocean’s ecosystem and, to an extent, the world’s. Without sharks and other apex predators, there wouldn’t even be an ocean.
• In Seeking Conversance, Jack learns about humans from a whale who tells him stories of the atrocities humans have committed against the ocean. One of them being the mass slaughter of dolphins. The dolphins were chased into a shallow area by humans and then butchered mercilessly. Only one dolphin survived, but not for long, as she was Driven to Suicide. Another sad case of Truth in Television, with places like the Faroe Islands having this as a routine practice.
