Elena looks away for a second, and looks back to see Tora gone.
"Tora?" She calls out. "Tora!" She dives under the water to see Tora slowly sinking down.
Suddenly, a monster swims out and starts attaking him. She swims over and pulles her staff from his grip. She hits the fiend a couple of times, before it swims away.
She grabs hold of Tora's hand and pulls him up to the surface.
