Below is a letter from Jason to Piper after he returns to the Roman Camp Half-Blood... It was once a one-shot, but imma add more fluff :) Enjoy!
Dear Piper,
As you know, I left a month ago to return to my "home" at Demigod Training Camp in California. I can't seem to wrap my mind around the fact that I grew up here; then again, I can't imagine being raised anyplace else. I'm discovering so much in this camp about my past. It's really a lot to take in.
One of the biggest things that I have learned is that… well, there is this girl named Reyna, and… She's really an amazing person. She knows me really well, she understands my predicament, she is very nice, and she makes one hell of a curry. I learned that we had had something before I had been abducted and brainwashed, and… well, she wanted to continue to be together after I got back here. She said that it would all be the same, and that we could go back to what we had been.
It was the same for her. It wasn't for me. With every kind word I said to her, and every time I kissed her lips, I only thought of you, Piper. It wasn't fair to Reyna. I left her heartbroken, Piper! I just couldn't keep on living that lie!
That's why I am telling you that I'm coming back. I just can't take this Demigod Training Camp anymore. I want to live with you on the Eastern Coast Camp Half-Blood! I need to! I need to see you and Leo again! But mostly you… Because, seriously, Leo can get a bit annoying. I have already been conversing with Percy, who, as you know by now, is regaining his memory within the confines of this hostile camp, to see if Chiron will allow me to stay there, even if Lupa doesn't know. I'm coming home!
It'll be great. We can learn and train together, just like you have always wanted! I don't even care if the other kids there look at me like I'm a freak. I don't care that I'm all alone in that scary Zeus cabin. I just want to see you again.
Nothing can keep me from you, Piper McLean. Nothing. I'll be seeing you within the week if the plans go through. If they don't, well, I'll still be seeing you. I'll run away, far away, all the way to New York so I can find you and have you to myself.
We can do this, Piper. You and I, I'll find a way for us to be together.
Yours,
Jason Grace
Fluffy? Yes. Response in the next chapter.
