It had been four years… four years since his parents had been killed by Zeus… four years and he didn't even get in trouble because of it. At this point only two Olypians knew where he was and one other that knew he wasn't dead. Apollo and Hestia had helped him over the years and Hades knew that he would sense if Percy died. He had changed more than they thought in the last war and would change even more during the next one
\\FLASHBACK\\
Percy had left the Egyptians a month ago. He had been helping a kid to the warehouse with one of the kids he was training to fight when it happened. A monster somehow got behind him and stabbed him in the back. Somehow he wasn't dead but luckily, or unluckily, Apollo just so happened to be riding his sun car over the fighting. He felt that this kid was important to a prophecy, but when he got to the kid he was already half healed and was helping the other kid repare the wood they had accidentally destroyed.
That's when he chose to inform them of something else in the area
"Ahum"
"Do you need something Apollo?" the kid that was injured a couple seconds ago asked.
"I want to ask you something… Who are you and how do you know who I am?"
"Do you seriously not remember your own Hero of Olympus… or are you just scared that it's me"
"Percy?" Apollo said hope in his voice.
"In the flesh" Percy answered
"I thought… I thought"
"You thought I was dead, didn't you?"
"I hoped not but still…. Wow… You've grown into a man...You're… you're still saving demigods?"
"Yeah, and added bonus I have a nickname… Steel"
"You're steel?" Apollo asked\ screamed
"Yes… now please don't scream" Percy said wincing when Apollo had screamed
"Sorry… but what happened to you… last we knew was that Hades had seen you… and the curse… do you still have it?"
"The curse? No… I thought Hades would have told you."
"Why would Hades tell us something he doesn't know?"
"Eh… he does know because he helped…"
"Where have you been?"
"Hiding… or I was, for like… a month… and then I found out that with this" he showed the metal bracelet on his arm" I could go around without anyone being able to track me."
"Hey, have you heard of the Prophecy that Rachel spoke before you left?"
"Uh… Yeah… I was the one that was with her but I didn't have time to tell anyone because two minutes later I was in Olympus being judged…"
"Did you understand it?"
"Swear on the river Styx not to tell anyone"
"I swear on the River Styx not to tell anyone about whatever you are going to tell me"
"good... Well, I can understand the prophecy... it says" After that Percy went on to tell the prophecy to Apollo
"Interesting... Who else knows?"
"Nico, Thalia, Will, Hestia. Annabeth Jason Piper and Leo have heard it but don't know if it's the real translation or the language... So they can't know for sure."
"Thank you, Percy... I must ask... Why are you still running?"
"The gods still hate me and the other's that don't are safer from Zeus rage."
"Even your dad?"
"Yes even him... Only you and Hestia know where I am now and Hades knows I'm not dead but that's it"
"Thank you, Percy, for telling me this... I swear I won't tell anyone"
"Thank's"
\\END FLASHBACK\\
Apollo did know but no one else had figured it out... But Percy had figued out his own things...
