We spent about half an hour in silence since Bianca left. No one wanted to comment to what we had learned from her. Apparently, I had an inner devil who had gotten loose...

/flashback\

"...Nicole di Angelo"

"What are you talking about, Bianca? I'm not evil and you know it! I've proven it! No one can doubt it!"I exclaimed enraged as Thalia tried to soothe me

"Relax, Nico, she never said you were evil. Let her finish"

"Right. As I was saying, you have an evil half, Nicole di Angelo. Every Hades kid has one. If you manage to live until the age of 14, it separates from your body. Until then, you are one. That's why when we were younger you had those...mood swings. Since you are now 16, your evil half - who, by the way, is of the opposite gender - lives freely as a real person. My evil half, Paul, died with me. You and your evil half have the same likes and dislikes, only since she left you, you are happier and she took all your misery. She was that miserable part of yours. The evil halfs get stronger when bad things happen to you. That's why you were mad at everyone when I died, you evil half had taken over.

Since during the war you had turned 14, she had to leave your body to move to her own. Which meant, she could die. And that made her furious and she blamed you. She somehow managed to survive the war but, even though she was neutral, she did kill many demigods. The gods thought she did it because she was helping the Titans and imprisoned her at dad's palace. Where she found you. And since you still - and always will - share your thoughts and know what's in each other's minds, she found out about Helen. Nicole always wanted to take her revenge, ever since I and Paul died. Paul was considered her brother, as you are my brother. So the best way to start was from you. Her plan was easily made from there and she kidnapped your girlfriend, knowing it'd hurt you more than any physical pain." The ghost girl explained.

"Why didn't your father inform Nico?" Percy asked, even though Nico still tried to process everything.

"I thought he had. He had told me he would even since he explained it to me, a bit after I died. But gods aren't known to keep their promises. Oh, and, something I forgot to say before. When she said trophy, Nicole meant she took your girl as her mate. Because as I already mentioned, you have the same likes. I'm not sure though if she truly likes her that way or she just wanted something her half had." Nico's sister answered the Sea Prince

"What can we do to beat her?" The huntress made the next question

"Not beat her, it wouldn't be advisable. Calm her down, that'd be better. You see, there are still rebels against the gods. And a demigod like her would be very valuable to them. She has the same powers as Nico and, since while they were together his life was full of pain, she's even stronger than him!

Be friendly with her and care. Deep down she's just a hurt little girl. And she needs someone to love her. Another reason why she took Helen, she was jealous of Nico."

They were all shocked by the sound of the dinner horn.

"I must go, my time is up. Meet me in the Underworld as soon as you can. Bring Annabeth and any other who can help us. Not Clarisse though. She's too mean for this work" The spirit advised and disappeared.

/end of flashback\

They returned to reality from the horn signaling the end of dinner. But no one cared. They exchanged looks and Thalia stood.

"I'm going to find the others and let my Mistress know. Percy, stay with Nico for the night." The daughter of Zeus instructed them, glancing worried at her younger cousin before exiting the cabin. Nico let out a shaky sigh and looked up at the other boy with watery eyes.

"Don't worry, Nico. We will make it and you'll have Helen back in no time. Don't worry about it, we will help you. All of us"
