Severus Tobias Snape

You were in your final year and had chosen Potions as one of your main subjects for the final exams. You still didn't know why. Of course, you were good at Potions, but Snape didn't like you, and that's why your grades weren't the best. Actually, you didn't care that Snape didn't like you, since you hated him too.

One day, you were in Potions class, silently preparing your assigned potion, and the person in front of you was doing the same. You could hear Snape's sarcastic remarks as he paced the classroom. Out of the corner of your eye, you saw your classmate's potion about to explode. You tried to move away quickly, but the potion hit you. Snape stormed over to your desk and glared at your classmate: "Detention this weekend, Mr. Weasley!" Before he could continue, you began to glow brightly. Suddenly, a small, luminous sphere appeared before your eyes, and a newborn baby appeared in your arms. Snape, like your classmates, was stunned by the sight.

Snape, cold and annoyed, said: "You may leave for today. For homework, you will write an essay about a potion. Now, go!"

Snape gave you a blanket to wrap the baby in, as it was naked and crying. He explained that Weasley hadn't prepared the potion you were supposed to make, but rather, due to a mistake, had prepared a potion that was once used to unite people who hated each other.

After a while, you followed Snape with the baby to Dumbledore's office, where Minerva and Dumbledore were already waiting. Since the situation with the baby wasn't simple and they needed to discuss what to do, Snape turned to you*.
Snape: "Okay, who's the father? Who have you hated the most lately?"
You frowned as you answered, holding the baby to your chest.
