He was running, but he didn't know why. There was no way they could have noticed he was missing by now. No way they could have found the note this soon. And there was definitely no way they could guess where he was going. He was safe, and his plan was safe.
Yet, there was a nagging sense that maybe, just maybe, he underestimated how much they cared, or how much they knew about him. But he pushed that thought away immediately. They didn't care. They had to have realized that they don't need him anymore. Al has his body back. Winry has the job she always wanted. As for Mustang, well, Ed had helped out enough. There was no reason he needed to stay. They would easily forget him.
After everything he had gone through, every homunculus he fought, every obstacle he jumped over, he managed to keep moving forward. But now it was time to rest. He only kept going because, with everything going on, he was able to ignore what was happening in his head. Things that no one would understand. He was Edward Elric, the famous Fullmetal Alchemist. He was a hero, the best alchemist Ametris knows. He saw the Truth, and bargained with it, sacrificing his only chance for a normal body to give his brother one. Yet here he was. Standing at this spot. A cliff with the most beautiful of views. A golden river stretching into the distance, towards the setting sun. After he and Al had finished their quest, and there were no more fulltime adventures and rescues, this had become his favorite place. Away from Central and Head Quarters and assignments and…everything. It was perfect. Nestled in the forest and practically secret, as no one else seems to go there. Here was the only place Ed felt happy and free. The best possible place to kill himself.
He respected the place too much to jump, though he felt that was a little ridiculous. He wanted the last thing he saw to be this horizon. And so he transmuted his metal arm into its all-too-familiar blade and he pressed it into his flesh. It dug into his wrist, and he could feel his pulse pushing back. He took one last look at the sun sinking behind the distant mountains. With one last breath, he jerked his arm away, and smiled as he felt his skin give way to the blade.
