[GORE.] It wasn't supposed to go this way. You just wanted to help.

You came looking for your sister and for your target. Maybe you never leave, just like her. Why not join in a swim? After all, the water is unusually warm, and thick. Darkening by the second, as her body sinks at the same pace.

At least you knew Fizz is alive. At least you weren't there when his breath stopped, but this? Your sister was dead. Your sister was dead. Your sister was dead....

Thirty-five years with her were sunk down the water, you watched her blood splatter onto you, you watched her explode, you were watching the water turn black.
