This is an AU where Percy and Thalia learned Italian to help Nico feel welcomed with other Demi-gods. Percy was taught Spanish when he was younger.

Nico sat at the Hades table picking at his lunch when Thalia and Percy sat at their tables. Thalia sat with the other hunters, Percy sat alone, Tyson was with their father this month.

Thalia looked at Percy with a questioning look, pointing her head at Nico. Percy looked at Nico to see that he hadn't touched his food. Percy nodded at Thalia, they both got up and went towards the younger of the three.

"Nico?" Thalia asked as she sat down next to her cousin. Nico looked up noticing his two cousins sitting in front of him. The rest camp had stopped and was watching the three.

"Stanno tutti fissando.(they are all staring)" Nico told them. "That's okay." Thalia told him. "stai bene, respiro della morte? (Are you okay death breathe?)" Percy asked their cousin. Nico shook his head.

Everyone was staring in shock wondering when they learned Italian. That was jus the beginning of them realizing how close the big three kids were.

The second time they saw how close the big three kids were was when Percy was upset.

Percy entered the training arena quietly cursing. By the time he got his sword out he was talking loud enough for everyone in there to hear. Percy started hitting the dummy as he was cursing in Spanish.

Thalia and Nico entered the training arena noticing everyone staring at Percy. "Joder, este estúpido culo, egoísta corrió el mundo! (F*** this stupid a**, egotistic ran world!)" Percy was yelling. The two finally realized why everyone was huddling away from the angry Son of Poseidon.

"Perce!" Nico yelled earning his cousins attention. "Si la muerte respira? (Yes, death breathe)" Percy said as steadily he could muster at the moment. "¿Qué sucedió? (What happened?)" Nico asked him, slowly coming closer. "Hermes decidió que sería divertido enviarme una caja llena de peces muertos. (Hermes decided it would be funny to send me a box full of dead fish.)" Percy said in a deadly tone. Nico and Thalia tried their hardest not to laugh earning them glares from Percy.

"Perce. I am sure Hermes thought it was just a prank. He more than likely didn't mean any harm." Thalia spoke calmly. "He sent a box of dead fish to the Son of Poseidon. I talk to fish on a daily basis. I have friends that are fish. What in his right mind gave him the idea I would find it funny!" Percy ranted. Nico smiled when he thought of the perfect solution. "We can give them a bariel. I will even make sure they make it to fish heaven. Okay?" Nico told him. Percy nodded and they left the arena to go Barry the fish.

The third time they saw how close they were was when Thalia had some trouble.

A guy was flirting with Thalia as she walked through camp. "No. I have said this a million times. No, I don't want to go out with you." That was all it took for Percy and Nico to show up.

"She said no. That means walk the Fu** away.." Percy started. Nico came up next to him and finished the sentence. "Or we will personally send you to Hades." Nico and Percy started to pull out their swords when he ran away.

Thalia shook her head as her two cousins looked as proud as they could be.

After camp realized how close the big three kids were no one messed with them. They no longer got surprised when they all randomly started speaking Italian or Spanish.
