We swam in silence, I lost the energy to speak, and my mind was numb for everything that happened. Why was Voldemort calling me 'Potter'? Is Marcus Voldemort's son?

We got to the shore and started walking to the main tournament grounds, everyone was still at the tournament, even Professor Dumbledore and Professor McGonagoll.

I had a flashback to the night Cho died, the same cold feeling when the Death Eaters came, the sudden darkness in the sky. The guy who killed Cho, the guy with the curly black hair. My mind was spinning with thoughts, am I a Potter? I've been an orphan as far as I know, I never had a home outside of Hogwarts.

"Y... Your, Voldemort's son?" I asked Marcus once I thought hard enough.

"I am, but I swear, I'm nothing like my father." Marcus said, I could feel him facing me but I kept my eyes on the ground.

"How do I know that for sure? Your father's Death Eaters go around and kill literal children who don't deserve to die at all. How do I know that you're not like him?" I asked, I felt my voice getting higher.

"Because I don't support him, I'm basically forced to spy on you. Or I'll get killed." Marcus said, his voice cracking.

"Why me? What did your dad mean when he called me a Potter?" I asked Marcus, this time looking directly at him.

"Because you're Harry Potter's sister. Didn't you know that?" Marcus said, looking right at me.

"N...No, I don't have a family. I'm an orphan. All I had was the Slytherin gand and... Cho, my best friend. But now she's dead." I said, looking back at the ground and I felt tears forming in my eyes.

"Cho... Cho Chang?" Marcus asked, stuttering.

"Yea, how do you..." And I realized. Marcus or Mattheo Riddle, was the one in the forest that night, who killed Cho Chang.
