Slytherin Boys_

Draco Malfoy, Mattheo Riddle, Theodore Nott and Regulus Black were in detention, Draco breaks the silence.
Draco:
—What the hell are we doing here?
Theodore makes a gesture of indifference raising his eyebrows, Mattheo responds with a slightly sarcastic tone.
Mattheo:
— I'll guess, detention.
Regulus, somewhat annoyed, gets up from his seat and approaches Mattheo.
Regulus:
— Are you behind this, Riddle?!!
Mattheo slightly closes his eyes and answers.
Mattheo:
— It is possible.
Suddenly Snape enters the detention classroom with that air of mystery and dominance, closing the curtains of the windows with a movement of his wand, Mattheo and Draco watch him as he approaches the desk, Regulus still annoyed warns Mattheo.
Regulus:
— If he ended up paying for your nonsense, I swear...
Snape interrupts Regulus speaking with that cold and dry tone.
Snape:
— Sit down, Black.
Regulus finishes his words before sitting down
Regulus:
— I swear I'll kill you, Riddle.
Theodore speaks looking at Professor Snape
Theodore:
— Why are we here, Professor?
Snape responds in a cold and cutting tone
Snape:
“It is… gratifying that my daughter has inherited at least one of my finest qualities… The intelligence to warrant her being sorted into Slytherin. On this point, let me be perfectly clear. If I hear even the slightest whisper that one of you has overstepped your bounds, whether through rumor, innuendo, or any of those pathetic games you are so notorious for, I assure you that you will wish you had never set foot in this castle. Now go.”
Draco, Mattheo, Regulus and Theodore leave the detention room, Theodore speaks first and in a low tone
Theodore:
—Snape has a daughter?
