Percy, Nico and Thalia were hanging out in the forest. Well technically they were rolling around in the forest. They got into a random argument about the shape of the clouds. No one really remembers how it started but next thing they knew they were all on top of each other trying to strangle one another.

It all ended when Thalia suddenly shocked both of them and jumped on top of the pile when they were temporarily dazed.

"I win."She said.

"No fair!" Percy said. "You cheated!"

"Yeah," Nico joined in. "If we could use our powers I would have won a long time ago!"

"Yeah right!" Thalia laughed. "And technically you never said anything about no powers."

"It was implied!" Percy screamed. "Neither of us were using our powers."

"That's why you lost." Thalia replied getting up. "Implying and assuming are pretty much the same thing. And they both take brain power which we know you don't have. So it's okay."

"I'm not stupid Thalia!" Percy's eyes flashed. Thalia backed up.

"Whoa. I never said that."

"It was implied." Thalia looked ready to strangle Nico again.

"Was not!" She yelled.

"It kind of was." Percy said.

"No it wasn't! You're impossible!"

"You're insufferable!"

"You'r-"

"-Giving me a headache! Both of you shut up!" Nico interrupted getting up and brushing himself off. They both glared at him.

"Whatever." They said.

Nico looked over to where Percy was fixing his shirt and briefly saw a white mark before it was re-covered by the shirt.

"Where did you get that scar Perce?" He asked.

"Another scar! Geez, Kelp Head, how many do you have?" Thalia exclaimed.

Percy looked to where Nico pointed and suddenly his eyes flashed with fear and remembrance.

"Nothing just a hell hound." He said.

"That's too big to be a hellhound Percy." Nico called his bluff. "Trust me, I would know."

"It's nothing. Just some random monster then."

"Too big to be a random monster either." Thalia's' eyes narrowed. "Plus you changed from your original story. Which means you're lying."

"Why does it even matter? It's over!"

"If it didn't matter you would tell us," Nico pointed out. "and it matters because we want to know what monster scarred our cousin/brother."

"Yeah, I've never seen a monster scar like that." Thalia added.

"Not all monsters are legends Thalia. Plus I'm fine so just Leave. It. Alone." With that Percy ran out of the woods to his cabin thinking about their conversation until he fell asleep.

*Olympus*

Up in the throne room Hestia was watching the two cousins interrogation of the third. She knew what happened. You can't hide things from the hearth. She wanted Thalia and Nico to understand what happened to Percy. But she knew he would never tell them himself. He wants them to know, but it's just too hard for him to talk about. So she started making a plan. She just hopes they don't ask too many questions before it's put into action.

*Camp Half-Blood*

The next day, Nico and Thalia approached Percy after lunch.

"You've been avoiding us." Thalia said.

"I have no idea what you're talking about. I haven't been avoiding anybody." Percy replied as he started walking away.

"Yes, you have." Thalia stated. "You've been avoiding us ever since our conversation yesterday."

"Yeah, what's the big deal about your stupid scar anyway?" Nico asked "Just tell us what happened."

"Nothing happened. It was just a monster. A very evil nasty ma-monster."

"You almost said something else instead of monster." Thalia pointed out.

"No I didn't. It doesn't matter just leave me alone." Percy said and then he walked away.

Thalia and Nico were about to follow him when there was suddenly a flash in front of them. They both instinctively covered their eyes. When the light died down they saw one of their favorite goddesses.

"Lady Hestia," They bowed.

"You do not need to bow to me children." She said. "I have come here to help you and your cousin."

"Are you going to tell us what happened?" They asked.

"No." They aw'd.

"Only he can tell you it is very personal."

"Families share personal stuff." Thalia pointed out.

"Yes, but this is a special case. He has to be the one to tell you."

"I think he made it pretty clear he's not going to tell us." Nico said.

"I know he has. That is why I have come up with a plan."

"What kind of plan?" They asked.

"A loophole. You will go back in time 5 years to one year before Percy came to Camp. You will go to the same school that Percy is and become his friend. Then you will get him to tell you." Hestia said.

"Why would he tell us then if he won't tell us now? Especially since it would have been a lot closer to the time it actually happened then." Nico asked.

"It will take time, but trust me he will tell you. Now would you like to or not?"

They each looked at each other and shrugged.

"It's not everyday you get the chance to go back in time and try to find out your cousins deep, dark secret." Thalia said.

"It sounds weird when you put it like that." Nico said. "But, yeah. We'll go."

"Okay. So, I will need to make each of you younger again after you get there so you will be the same age as Percy, eleven. I will enroll you in the same 5th grade classroom at his current elementary school as him. You will stay at Camp Half Blood when you aren't with Percy. You can explain anything or everything you want to anyone or everyone you want. It will not affect the future. I will erase the paradox once it's over. Only you two and Percy will remember when you get back."

"Wait, wait, we have to go to school?!" Thalia asked incredulously.

"That's where you'll find Percy."

Thalia sighed. "Fine."

"It's going to be hard to explain how you're not a tree anymore Thalia." Nico said.

"I actually forgot about that." She said.

"But wait, what about the Hunters? I'm only on temporary leave."

"Time will not go on here until you return. Except for me I will be watching and send help if you should need it."

"Okay let's do this."

"Be careful." Hestia warned.

"We will and thank you Lady Hestia." Nico responded.

"Just Hestia. Goodbye young heroes."

With that Thalia and Nico were sucked in a vortex. It felt like they were being ripped apart molecule by molecule but peaceful at the same time. After what felt like a millennium they found solid ground again.

"Ow! Get off me Death Breath!"

"You're on my leg Pinecone Face!"

"Well your other leg is on my arm!"

"Just move your leg so I can move mine and we can get up!"

"Don't tell me what to do! Why should I move first? You move your leg!"

"I can't! Your whole body is on my leg!"

"Then shadow travel!"

"Were at a campfire Thalia! There aren't exactly a lot of shadows right by the flames!"

"Ugh! Just...!"

When they finally got up, they looked around. They had landed right in the middle of the campfire. (The event not the flames *eye roll*). Just our luck. They thought. Everyone at camp was staring at them.

"Who are you!?" Someone shouted.

They turned to find blond hair and grey eyes.

Annabeth gasped. "Thalia?"
