AN: Sorry for the wait, but I was on a school trip for a week so I wasn't able to upload, but I'm back now and so here's the next chapter.

Thalia lay awake in her bed in Cabin One. She had just finished her second quest to receive the Golden Fleece. When she had found out Percy's Pine had been poisoned, she had been angrier than she had ever been in her life. The fact that it was Luke who had done it hurt even more. The person she once looked to as an older brother had completely and utterly disrespected the sacrifice made by Percy for them four years ago.

She could still remember on her quest to retrieve her father's bolt the year before when she found out of Luke's betrayal. She had been chosen to lead the quest and had chosen Luke and Grover to accompany her, as Annabeth was only 10 and too young to go on a quest.

Ever since the death of Percy, Thalia had been very protective of Annabeth, protecting her from bullies and always helping her. She refused to let something happen to her, like what happened to Percy.

For the first few months after his death, they had all grieved, but Thalia was affected worst of all. She was in an almost catatonic state for three months. She barely ate and rarely left her cabin. Luke began to train harder and more ferociously, thinking that if he were stronger then no one he cared for would have to get hurt again. While they were both dealing with grief in their own way, Annabeth was left all alone. As she was only seven, she was one of the youngest at camp and was frequently picked on. During this time she became very close to Chiron, the activities director at camp, and he became a father figure to her.

Luke eventually learnt to better deal with his anger and began to look after Annabeth, Percy's last words to him still ringing in his head. He had promised to keep them safe and he would do everything he could to fulfill that promise. He made sure people stopped bullying Annabeth and was always by her side whenever he could be, but Thalia was still just as despondent as before until one day se snapped out of things.

It had been on one of the rare occasions she left her cabin when she saw Annabeth alone and surrounded by three Ares campers who were pushing her around. Luke had been at one of his activities and so Annabeth was alone. Thalia instantly charged at the group and attacked. By the end of it, the three campers were unconscious on the ground as Thalia stood over them. She still remembered what Annabeth had said to her next.

"Thalia. Can I have my sister back?"

That simple question snapped Thalia out of her state of mind as she realised how disappointed Percy would have been with her. He wouldn't have wanted her to let herself wither away over him. No! He had sacrificed himself so she could live and she would not disrespect his memory by not doing that. After that day she was back to being her old self. She still held a deep sadness within herself, but she accepted it and moved on, determined to look after her family.

That all changed on the quest the year before, when finally after retrieving the bolt and escaping Hades, after a very intense encounter, as both Thalia and Luke hated him intensely for the death of Percy, Luke revealed himself to be a traitor.

She still remembered it happening vividly.

Flashback

As Thalia, Luke and Grover appeared on the beach they saw a huge muscular man waiting for them. He had scars on his face from various battles. He was Ares, the god of war.

"You stole the bolt Ares! Why?" Thalia shouted.

"I didn't steal the bolt. Gods can't take each other's symbols of powers brat."

"Don't lie. It was in the bag you gave us." Thalia retorted.

Ares smirked, "That's true, but I just procured it off of the actual thief, who I believe you know very well."

"What are you talking about?" Thalia took a step forwards. Ares simply nodded his head towards Luke.

Thalia turned to look at him, "What's he talking about Luke?"

Luke looked up at Thalia and stepped away from her and Grover.

Thalia was stunned, "Luke. No."

"I'm the thief." Luke announced.

"Why?!" Thalia and Grover screamed.

Before he could answer Ares cleared his throat behind them. "While this is great and all I do have to kill you now." As he drew his sword he suddenly stopped, looking like he was listening to something. He turned back to them, "Well it looks like you kids are in luck."

Before any of them could say anything he had flashed away. Thalia and Grover both turned to face Luke again.

"Why Luke?" Thalia asked.

"It is time for the reign of the God's to end. They are unworthy to rule."

"What are you talking about Luke? The Gods and good to us. They're our family." Grover said.

"Family don't let each other die when they can do something!" Luke screamed. Thalia and Grover both took a step back in shock. They both realized he was talking about Percy.

"Percy chose to sacrifice himself. You know they Gods aren't allowed to interfere." Thalia argued.

"But Hades is allowed to send monsters to kill us? If they cared for us then we would get to see them sometimes. There wouldn't be any unclaimed campers in the Hermes cabin wondering if their parent's care for them at all!" Luke was screaming at this point.

"Luke stop please. This isn't you." Thalia was practically begging by this point.

"No Thalia. This is me. My master will make sure that the Gods fall and will pay for what they have done."

"Percy sacrificed himself for you and this is how you repay him." Thalia shouted.

Luke's face twisted in anger. "I'm doing this in his memory." He snarled, "Do you not remember what he went through before he met us? His father let that happen when he could have stopped that any time. He let his own son get tortured for years and you still think they care? If Percy were alive now he would be sided with me."

"Don't you dare say that!" Thalia screamed furiously. "Don't say that about Percy. If that's what you think then you clearly didn't know him at all."

"You know it's true Thals. You can still join me." He looked at Thalia with pleading eyes.

Thalia looked away with tears in her eyes. "I don't even know you anymore Luke." She then pointed the Master Bolt at Luke. Luke's eyes widened before they narrowed.

"Fine Thalia, but know that next time we face each other we will be enemies. Bye Thalia and Grover." With that he quickly pulled out a sword from seemingly nowhere and made a slash in the air that he then jumped through.

Flashback end

Thalia remembered how heartbroken Annabeth had been when she had been told of Luke's betrayal. She refused to believe it at first, but eventually accepted it and was distraught for weeks. She had now lost both of her big brothers and heroes. She then began to throw herself into training so that the next time a quest was issued she would be on it.

Thalia eventually had to stop her as she barely getting any sleep and looked terrible. Thalia wasn't holding up much better, but had to put on a brace facade as the de facto leader of the camp.

When this summer had come and Thalia had found out Percy's tree had been poisoned she was terrified. She thought she was going to lose the last part of him and that thought upset her to much to put into words. The fact that it was Luke who did it, hurt even more.

When Chiron was blamed and then Clarisse was chosen to go on the quest to retrieve the Golden Fleece ahead of her she was angrier that she had ever been, as was Annabeth. Annabeth quickly worked to deduce that the Fleece was in the Sea of Monsters and she and Annabeth, with some help for Poseidon, who also did not want the last remnant of his son to die, managed to get to the Sea of Monsters.

After narrowly escaping death numerous times, they managed to get the Fleece with Clarisse and also found Grover on the Island of Polyphemus. When they arrived in Florida they had sent Clarisse off with the Fleece to camp. They had then encountered Luke and a group of monsters, where they found out for certain that he served Kronos, who was rising. They had managed to escape with the help of the Party Ponies who Chiron had been staying with.

When the Golden Fleece was placed on the tree, they were all worried for a second that it wouldn't work, but as soon as it was placed down the tree glowed brightly before it began to heal.

It had now been three days since that and they had guard patrolling the tree until they could find something to guard it.

Thalia was about to fall asleep when someone barged into her cabin. She shot up instantly to see Grover standing in the door.

"Thalia! Come quickly."

Thalia immediately hurriedly got up and followed Grover. They ran towards the tree and the whole time Thalia was worried that something had happened to it. She expected to see the Fleece missing but instead they arrived to see Chiron and a group of campers around the tree as Annabeth, who had been on guard duty, was kneeling next to an unconscious boy on the floor.

"He… just… suddenly appeared…" She mumbled with tears streaming down her face.

Thalia took a closer look at the boy as realization suddenly struck her. She began to walk slowly towards the boy. 'It can't be.' She thought to herself.

She slowly knelt down next to the boy and lifted him up slightly as suddenly his eyes snapped open and she was looking into the most beautiful sea green eyes. Blue met sea green as they looked at each other.

"Thalia." He softly mumbled before his eyes closed.

Thalia began to hold him close to her as tears began to cascade down her face.

"Percy. Percy. Percy." She kept repeating as she held him close to her. She felt another pair of arms encircle her as she looked to see Annabeth as they both began crying together.

Percy Jackson, the Son of Poseidon, was back.
