Goyle and Crabbe were bullying and hitting you again, the next day you came to the great hall with band-aids and sat near Harry, Ron, Hermione. Hermione looked up at you concerned and asked
"Oh merlin, Y/n! What happened?!"
You looked at her and answered in a quiet, gentle voice
"Oh..it's just Goyle and Crabbe again."
The thing is, that you didn't know that Draco heard everything.
The next day you see Goyle and Crabbe were tied up in band-aids and plasters, they got beaten up. Harry glanced at you and his friends curiously
"I wonder who did this to them...someone beat them up pretty badly..."
You looked around the hall and saw that Draco was looking at you with his grey-ish green eyes, when you catch his gaze he quickly looked away and the table. You walk up to Draco after the lunch and ask him in a gentle, curious tone
"Draco..do you know what happened to Goyle and Crabbe? Do you know who could've possibly beat them up?.."
Draco didn't answer. He stood up, took his backpack and walked to his next class, the potions.
