Percy v river gods

I dove into the murk and sank to the bottom. I tried to find the spot where the two rivers' currents seemed equal — where they met to form the bay. I figured that was the best place to get their attention.
"HEY!" I shouted in my best underwater voice. The sound echoed in the darkness. "I heard you guys are so polluted you're embarrassed to show your faces. Is that true?"
A cold current rippled through the bay, churning up plumes of garbage and silt.
"I heard the East River is more toxic," I continued, "but the Hudson smells worse. Or is it the other way around?"
The water shimmered. Something powerful and angry was watching me now. I could sense its presence ... or maybe two presences.
I was afraid I'd miscalculated with the insults. What if they just blasted me without showing themselves? But these were New York river gods. I figured their instinct would be to get in my face.
Sure enough, two giant forms appeared in front of me.


They floated toward each other, ready to fight.
"Hold it!" I yelled. "We've got a bigger problem."
"The kid's right," East snarled. "Let's both kill him, then we'll fight each other."
"Sounds good," Hudson said.
Before I could protest, a thousand scraps of garbage surged off the bottom and flew straight at me from both directions: broken glass, rocks, cans, tires.
I was expecting it, though. The water in front of me thickened into a shield. The debris bounced off harmlessly. Only one piece got through — a big chunk of glass that hit my chest and probably should've killed me, but it shattered against my skin.
The two river gods stared at me.
"Son of Poseidon?" East asked.
I nodded.
"Took a dip in the Styx?" Hudson asked.
"Yep."
They both made disgusted sounds.
"Well, that's perfect," East said. " Now how do we kill him?"
