Over an ocean, birds were flying and porpoises were swimming happily. From the fog a ship appeared crashing through the waves.
Castiel stood on the ship with Bobby, the wind blowing through his trenchcoat.
"So you said that you received a distress signal from Atlantis?" Bobby said.
"The crystal alerted my grace, yes." Castiel said.
Sam looked down into the sea. "So you and Cass time traveled to Atlantis and stayed there for a year?"
"We prevented Rowena from capturing the crystal the first time, but it resulted in the sinking of the whole island." Bobby said.
"Why does Rowena want Atlantis?" Sam asked.
"She wants power. Always power." Dean said, rolling his eyes. "You really believe in mermaids then?"
"They ain't mermaids, boy!" Bobby said. "They are perfectly human or were—"
"Until they had to evolve." Castiel finished. "If they return to land they will become human again."
"So Rowena wants the crystal of Atlantis." Sam said. "How do we stop her?"
"The Heart of Atlantis lies in the Eyes of her King." Bobby said.
"So we find the king?" Dean asked.
"I am the king." Bobby said. "I went down there and took up leadership to save them. Down there...fathoms below."
