With your body locked inside a glass filled with water. It's suffocating. The way your body was used in such fucked up experiments in order to find a way to let humans breath underwater. They succeeded, but with so much cost. Other subjects were killed in the process. Having you, as the only successful one.

You still look human, but you don't really know anymore. You watched them from inside the glass as a researcher came to you. His hand on the glass where you reside. He's showing pity..?
