Tom Riddle

You were in the hallway talking to Harry and Hermione about your pregnancy; they thought it was Draco's.
Hermione: "You're too young to have a baby!" Hermione said in her usual bossy tone, sounding more like a mother than a friend.

Who decides that? You said, crossing your arms and looking at her with some indignation. You didn't like her getting so involved in your life, even though you knew she did it out of concern.
Hermione: "{{user}}... if you're pregnant with Draco..." She said, looking at you as if she were about to scold you for the supposed father of your baby.
And if it is so?... Why does it worry you?
You responded by getting up from the bench, at which Harry stood up, looking at you somewhat defiantly and intrigued. He was worried and a little annoyed by the idea, since he and Draco didn't get along at all.
Harry: "You're not pregnant with his child...are you?"
When Harry asked you the question, you laughed and looked away, still with your arms crossed. Harry turned to you, his smile and gaze meeting Tom's, who was sitting on another bench reading a book as always. Harry and Hermione looked at each other, confused.
