Disclaimer for entire story: Rick Riordan and DC comics own the characters, setting, etc. I only own most of the plot(ICan'tPickAFavFandom owns the beginning concept of Percy being Bruce's childhood friend and Bruce thinking Percy is dead)

Percy

After the giant war, I went home to find that mom and Paul had been murdered by Gaea. Since I was already eighteen, I could live alone. After that, a thought occurred. I felt the urge to visit my friend (who I secretly had a crush on) Bruce Wayne, whom I had met when I was nine. We had met when we both ran away- me from Gabe's abuse, and him from his parent's death. We had bonded quickly. I had told him about my heritage, and the prophecy that had been issued at that time. Bruce probably thought that I was dead.

Flashback

I was walking in the woods. Gabe had threatened to hit me, and mom... mom had told me to temporarily run away. Suddenly, I heard sobs of grief. It sounded like a young boy. Why was he here? I thought. I looked behind a colossal boulder to see a boy about my age sobbing.

"Are you O.K?" I asked.

"Yes. I ran away," he replied.

"Why?" I inquired.

"I... I just wanted a place to be away from adults," he explained.

"I also ran away," I said, surprised. "My stepfather is abusive. My name is Persephone but call me Percy."

"I'm Bruce,"

Flashback ends

Bruce... what if Bruce had been murdered by Gaea as well? She had taken the lives of the seven, Nico, Thalia, Clarisse, Reyna, Will, Katie, and my parents. What if Gaea had traced Bruce's connection to me and killed him? I thought. My heartbeat quickened, and I vapor traveled away to Wayne Manor.

Bruce

Dick and I worked alongside each other. Suddenly, Dick asked, "Dad, have you ever fallen in love?"

"Yes," I replied thoughtfully. I felt sorrow. Persephone had probably died. "Her name was Persephone, though she preferred to be called Percy. We knew she would die when she was sixteen."

"How?" my son inquired.

After debating whether I should tell him, I decided to explain Persephone's heritage to Dick.

"She sounds like she was a hero," noted Dick. "What did she look like?"

I wordlessly brought out a picture of me and her.

"Will you ever get over it?" asked Dick softly.

"No," I replied, remembering her eyes filled with love and loyalty. If only Persephone was still here...
