I'm back!! You guys, I'm so, so, so, so, so sorry for not updating but I just looked at your guys suggestions, and I now have inspiration! This suggestion comes from @Redhood11686 thanks for the great suggestion, and let's get straight into it!

Steve's POV
Where is he? Where is my little boy? Where is the boy that I saved, and who saved me? Where is my Percy?

Percy has been gone for a year!(sorry idk the actual amount of time) I missed his birthday, he's now 18. He came home for 2 months, and than Annabeth, his girlfriend, came and told me he was gone. Vanished, without a sight. I've been worried sick. He called once, and left a message but that made it even worse. I heard his voice, and I can't even save him. I'm supposed to be his father.

I don't know if I'll ever see him again. The rest of the team has lost hope. I haven't, I know that he'll be back soon. I'm on the couch right now, looking at the photo album I got from his home. I added a few pictures, and am thinking about all of the easier days. When I'm just getting into it, when hear the door to the elevator ding. The rest of the Avengers are out so I get up in a defensive crouch thinking it's an intruder. It's not. It's the best thing I could see.

I see a tall kid with black hair, pale skin that used to be tan, and see green eyes that used to be bright but are now dull and broken.(Tartarus will be different.) I know right away who has just walked into my home. It's Percy. My boy who's not really a boy anymore.

I rush over to him and hug him. His body feels so thin, and frail. From what? I don't know and it's very worrying. He hugs me back, and starts sobbing on my shoulder. I hold him there, and never let go because I know he needs an anchor right now, and that's me.

When he stops crying, I hold him at an arms length and look at him for the first time. His skin is very pale, he has dark bags under his eyes, broken eyes, and worst of all, scars on every part of skin I can see, even a few on his face. There not all scars I noticed , some of them were open and bruised.

"We need to get your wounds dressed, and than we'll talk." I told him.

"No, I deserve this." He responds in a hollow voice. Oh no, it's much worse than I thought. He has PTSD, and he's got it really bad.

"Oh Percy, you deserve anything, your the bravest person I have ever met. You've saved countless people, and alway, always, put yourself last. You don't deserve any pain, especially not all of this." I told him with lots of compassion.

"You don't know what I did." He whispered barely audible. "Can we sit down? I feel like I might pass out." He said just barely louder.

I moved him to the couch, and he immediately drooped into it, and didn't move. I got up to get him something to eat, but he held onto me tighter not letting go. I fell back next to him, and put my arm around his too thin shoulders. Almost instantly, he fell asleep. I wanted to ask him so many questions, but I knew I couldn't pry. Not when he was in this state.

When it was almost midnight, I woke him up so we could go to his bed. When we got there he fell on the bed, and was out again. I went into my room, right across from his, and went to bed as well.

I woke up, not knowing why when I suddenly heard loud screams. I jumped out of bed Andean to Percy's room. He was still sleeping, but was crying and screaming in his sleep. I woke him, it difficulty, and  suddenly everything came out.

He told me about the...the war, Tartarus, and how he was tortured by Kronos there to save Annabeth. It kills me to think that he was on the brink of death, and I was sitting here doing nothing. With most regret, he told me of how they lost some kids in the war.

"There kids dad, there just kids, and now there dead. Their parent wont see them again." He told me and started crying even harder. I sat there and comforted him, not saying 'it's okay' because to him, everything is not ok. He fell asleep, but I stayed with him this time, I didn't leave his side.

When he woke for the second time, I told him that he need to eat, right away. He was hesitant, but I was adamant, he was eating no matter what. I gave him some eggs and toast. He didn't eat much even though I pushed him too. I cleaned off the plates, and found him sitting in the living room staring at the blank TV. I sat by him, and we didn't say anything. He needed my presence right now, and I would gladly give him what he needed.

I knew things would be strained for a while, and probably never really be the same, but someday it's gonna be ok, and as long as that happens, life will still be great.

So that's it. I hope it's ok, I did my best🙃

See you guys next time!
