Because I can easily relate to his character. We're very much alike, Jason and I, you know, apart from him being a demigod, of course. You see, I'm a child of divorced parents. Much like Jason, I had two sides to pick, too. I don't know of any other PJO character who's more like me than Jason. So, you see, Jason and I are much more alike than you can think of. I'm not a demigod, or son of Jupiter like Jason, and I don't get to throw lightning bolts or fly on air like he does, but we both share the same personality. In short, Jason is divided inside, much like me. I can understand exactly how he feels, and that's what makes him so special. Now you know why I like Jason Grace so much.
