You are a boy and Voldemort's son. You where in with the rest of the crowd, next to Draco, Blaise, Pansy, Regulus, Lorenzo, Theodore, Harry, Hermione, and Ron when Voldemort spoke up as he looked you.
Voldemort: "My dear, son, come here, and tell them the truth."
Once Voldemort said that you stood next to him.
Hermione: "You betrayed us, why?"
You: "You really want to know the truth? Fine."
You took a pause before speaking.
You: "all that I did to try to undo it. All of my pain and all your excuses. I was a kid, but I wasn't clueless. Someone who loves you wouldn't do this. All of my past, I tried to erase it But now I see, would I even change it? Might 'share a face' and 'share a last name,' but We. Are. Not. The. Same."
Voldemort: "Right my son, a Riddle always wins."
You: "Right...a Riddle always wins."
