2-Nico
Nico was absolutely ecstatic that his two best friends had made it safely—well, as safely as was possible—out of Tartarus. He was the son of Hades and he barely scraped by with his life.
Nico wasn't happy often, so the fact that he was actually ecstatic about something was kind of a big deal. Yes, he had his 'sister,' but she was Roman, a daughter of Pluto, not Hades… and she would never be Bianca. He'd brought Hazel back because it's what his father wanted and because it would seriously tick off Persephone, Queen of Evil Stepmothers.
Frank was alright, but kind of a big oaf and he didn't really like seeing his sister with a boyfriend, it was good that she was happy and all, but that guy was a son of Mars and could turn into a draken- not exactly the safety rating he wanted.
Leo was probably the most ADHD demigod ever and he could spontaneously catch fire, seemed to have a crush on Hazel, and take pleasure in annoying absolutely everyone around him. Even Nico had to admit though; he had some mad skill when it came to machine works. Nico doubted even Charles Beckendorf could have made a war ship like the Argo II.
Jason was like a super up-tight, almost as talented, Percy. He was all about leadership. Where Jason was trained to be a leader, Percy took it in stride. He was the son of Jupiter and Nico could just tell that his entire life that simple fact had been his defining characteristic, people chose him to lead because he was the King of the Sky's son. People chose Percy to lead because he was just good (a good person, a good fighter, a good friend, a good leader). Nico just didn't know about Jason. He suspected that Jason was jealous of Percy, but couldn't be sure. If spending all of his time with the dead and damned, which it did, it would be that he knew more about them than the living. It was hard for Nico to read people. It seemed like Jason tried to be a leader, and Percy just lead. They did work well together. Even Nico could see that. When those two put their powers together, giants barely stood a chance.
Nico wanted his strength back; he wanted to fight alongside his cousins. When he and Percy and Thalia had worked together, they had been practically unstoppable, the children of the three eldest gods. Nico wondered if that's why he wasn't sure about Jason, because Jupiter was newer than Zues.
And then there was Piper, daughter of Aphrodite, most powerful charmspeaker in a century, and, of course, girlfriend to the blonde Superman himself. She was seriously hot, even if she tried not to be. When your mother is the goddess of love and beauty and your dad is the "definition of old-guy sexy" (according to Thalia), Nico figured you really didn't stand a chance of not being gorgeous. Not that she noticed Nico as anything more than the death kid. Nico was destined to be alone, or so it seemed to him at least.
He imagined dating a mortal and telling her that he was a demigod. In his imagination, she didn't freak out, she simply exclaimed That's so cool! Who's your godly parent. To which Nico would reply: Hades is my father. And then she would run away screaming for her life.
Ya- that was really the most positive outcome he could think of.
When Nico was about ten, he'd had a huge crush on Annabeth. Hey! She'd gotten kidnapped to save him. He was almost three years younger than she was and there was Percy. Once those two finally got together, everyone at camp was like: duhhhh. Nico completely agreed with that. It's like they were made for each other: Percy making Annabeth a little more impulsive, getting her to not think things through so much and have more fun; Annabeth calming Percy down, bringing some logic into his life, and making him genuinely happy.
Anybody who can fall into Tartarus to save his girlfriend got a five-star rating in Nico's book, and any couple who can survive that place together, well- Nico knew that they loved each other more than anything in the world.
As he lay in Percy's cabin- his cabin now?- he thought about all of these things. He thought about how he had almost closed the Doors of Death just when Annabeth and Percy leaped through; he thought about his father and mother and stepmother; he thought about—BANG!
Nico was thrown out of his bed as the ship lurched sideways.
