Nico's POV

"My-my name is Nico," I stammered. Darn, I was so stupid. She turned and regarded me with her beautiful green eyes. She smiled. Her eyes widened.

"Deo? Is that you?" She asked hopefully, seemingly staring straight into my soul, like an old friend.

"N- No. I am Nico, but I can be Deo if you want-" Percy snickered behind me. I am such an Idiot! But it seemed to amuse her. She turned back to Percy and Annabeth.

"My name is Annabeth," she announced calmly. "And apparently this is your brother!" Percy gave Annabeth an urgent glance then smiled nervously at Sirena.

"Hey. I'm Percy. So you're an Olympian huh?"

"Yup. Speaking of which, I have some duties to attend to in the underworld. How is my dear Uncle?" What was she the goddess of? I would insult her if I asked, I learned that the hard way. (Sorry Persephone) Luckily, Percy took that one for me.

"So what are you the goddess of anyway?"

"I am the female equivalent of our father and Hades, the goddess of death and the sea."

"That's pretty cool!" He said, clearly impressed by his sister. She gave him a grateful smile, and turned to Poseidon. Her raven black hair shimmered as she turned.

"Father, where is my crown?" she asked. Poseidon smiled, and a crown with onyx and sapphire crystals appeared in her hair, but morphed quickly into a headband.

"Your beautiful," Why did I just say that? I felt their eyes boring into me, surprisingly Sirena smiled kindly at me.

"I hope you were referring to me," she said.

Sirena's POV

Deo's, I mean Nico's, cheeks were bright red. It was so cute! He reminded me so much of Deo. At this point you are probably wondering who Deo was. Billions, maybe even trillions, of years ago, Deo was my boyfriend. Being so long ago, I don't remember anything but his face, and that I saw it every time I stole a glance at Nico. And every time he stared into my eyes, it was like seeing Deo again.

"I mean, the crown is beautiful, and so is your hair, no I mean-"

"Don't apologize" I said, smiling. "So are you." His blush deepened. Annabeth laughed, while Percy shifted nervously.

"I must go see Hades. Would anyone like to join me?" I said clearing my throat.

"How do you plan to get there?" Percy asked, I laughed.

"Percy, my dear brother. I am a goddess, am I not?" I said laughing. Nico dissapeared in a blur of shadow, taking Percy with him.

"Looks like they can shadow travel. Bye, Lord Posiedon. Annabeth, would you care to join me?" She nodded, and took my arm, and we swirled into nothingness.

Underworld

"What? She's back? No, she can't be! Do you know how long she has been gone?"

"Hello, Uncle? How is life in the underworld?" Nico, Percy, and Annabeth laughed. Hades smiled.

"Father, have you heard from Bianca?" Nico asked, who is this Bianca?

"Who is Bianca?" I asked politely. Nico's face darkened.

"My sister. She died awhile ago." Nico glanced at Percy, who was suddenly interested in his converse.

"Oh. I'm so sorry."

"S'okay. I can still see her, and I don't blame Percy anymore." Hades cleared his throat.

"Sirena, where have you been? You abandoned your duties here-"

"Where do you think I was Uncle? Off Galavanting with horses? If you only knew what torture- Never mind." Nico became more alert than he had before, Percy and Annabeth broke off from their own conversation and looked at me.

"What happened" Nico was the first to ask.

"Nothing. Nevermind." I whispered "I can't talk about it. It would be torture just talking about it."
