Okay, so this one's a little inconsistent to the series, but my friend told me this was a good idea so I'm doing it. I like Frank too much to put him in this situation. We came up with it while watching Disney's Hercules. So here it goes…

Nico was walking down a busy New York sidewalk. Today he had traded his signature Aviator jacket for a regular grey hoodie. He had the hood pulled up over his head, hiding his shaggy black hair and pale face. He had his eyes focused on the couple in front of him.

One of the people was a dark skinned female. She had curly brown hair. She was short, only about 5'3''. She appeared to be 14 or so, but Nico knew better. She was nearly 70 years-old. The girl was Nico's sister, Hazel. He'd brought her back from the Fields of Asphodel about a year ago.

The person with her was her boyfriend, Tyler. He was tall, way taller than Hazel. He was nearly 6 foot and had a muscular build. He had short, blond hair and chocolate brown eyes. Nico didn't trust him. It was something about him. His hair? His eyes? His smile? The fact that he was 16? Nico couldn't exactly put his finger on what bothered him about that guy.

He was always quiet around Nico. He barely uttered a sentence in his presence. Nico felt proud of that. He scared Tyler. He was only about 5'6'', built like a stick, and he scared a guy that was competing with the Hulk in size.

Hazel and Tyler were out on a date. They went to see a movie. Nico followed them into the movie, blending into the shadows- an art Nico was perfecting. He sat 2 rows behind them. Close enough to keep an eye on them, but far away enough to not be caught.

As the lights dimmed, Tyler put his arm around Hazel. Nico wanted to jump over the seats and rip his arm off, but restrained the urge. He didn't pay any attention to the movie. Instead, he chose to stare at the back of Tyler's head so intensely that Nico thought he would burn holes into it.

At some point, in the middle of the movie, Nico noticed Tyler's head move. He turned to look at Hazel. Nico saw the look on Tyler's face. Nico could tell he didn't like the look he was giving Hazel. It was the look someone gives a piece of cake when they haven't eaten anything in 3 days. He didn't care who it was, Nico didn't want anyone looking at his sister that way. EVER. Nico had the clench his fists around the armrests. He squeezed his hands so hard the armrests crumbled and fell off. Nico, startled, dropped the pieces and kicked them aside, acting like he'd done nothing wrong.

After the movie finished, Nico snuck out of the theater, still following Hazel and Tyler. He didn't know Hazel was a demigod, so he dropped Hazel off at the bus stop. He went to kiss Hazel, but he must've sensed Nico there because he just gave her a hug, waved, and walked away.

After seeing Hazel got safely on the bus, Nico shadow traveled back to Camp Half-Blood He was sitting on his bed, in the Hades cabin when Hazel returned.

"Hey, Hazel, where you been?" Nico asked casually.

"Out," she said. "With Tyler."

"Oh," he said, as if he didn't already know. "What did you guys do?"

"We went to a movie."

"He didn't pull anything on you, did he?"

"No, Nico," she sighed, exasperated. "I promise you, he's a good guy."

"A good guy?" Nico asked, disgusted.

"Yeah, 'a good guy' He's different from other guys. He's sweet and he cares about me," she defended, raising her voice.

"HE'S A GUY!" Nico nearly yelled.

Hazel flinched back. They've had little arguments before, but they've never yelled at each other.

"Look, Hazel. I'm sorry for yelling," Nico started in a soft voice. "I just want to make sure you're okay. It's just that I don't trust that guy."

"Nico, I'm 14. I'm not a little girl anymore. You don' t need to protect me all the time."

"I'm your older brother, it's my job."

"You're not going to be able to protect me from everything. I'm going to have to fight my own battles sometimes. Trust me."

Nico sighed.

"Fine, but he does one thing wrong, I swear to the gods-"

"He's toast," Hazel finished, smiling.

"And you know I'm only trying to warn you because I know how teenage guys are. I love you and I want to protect you."

"I love you too, Neeks."

Nico walked over to Hazel and hugged her. She stretched up to kiss him on the cheek and walked out. As soon as the door shut, Nico's smile faded. He sighed and flopped back on his bed. No matter how much she reassured him she would be fine, he would never trust Tyler.

'He's still a guy," Nico thought.
