You are enemies, he's a Malfoy, you're a Granger

You are walking in the hallways of Hogwarts at a late hour. When you turn around, you see Scorpius looking at you while laying on the wall with his arms crossed

Scorpius: you shouldn't be here at this hour,Granger. What if I say it to someone? He says getting closer to you

You: you are here too, Malfoy

Scorpius: Oh Granger, I am doing my patrol time. He says smirking, he is very closer to you
