Brice sighed and drank more of his butterbeer, staring at the table for some seconds before raising his head and looking at her with an penetrating look, trying to see if she was just curious, or something else. After a couple seconds of that awkward staring, he finally said:
"Well, I'll say it. Dark Arts is a weapon, not something everyone should have and use in free will. Everything related to it, they're weapons, and that includes curses, poisons, herbology, and basically every other thing you have here. I suggest you stick to the things you're taught here, but if you really must know, you should use the Dark Arts to protect yourself, and your valuable others. There isn't much to say, you have weapons, and if you use them the wrong way, you're done. Oh, and before you ask, I do know the curses. They're not something that you should play with, in any means. They were not made for good things, and I can't think of any good way to use a torturing method, or a killing curse, or even something that makes someone get completely controlled by you. Poisons are a less delicate topic though, since it mainly involves poisoning people, but can also be used to get rid of pests, defend a secret, and much more. And of course, I think everyone has the topic of herbology with carnivore plants. I just hope we have more here, since most Dark Arts classes were the same things... and they are not nice. Mark my words."
Upon finishing, he took another sip of his butterbeer and looked inside her eyes with the penetrating look again, which made most people instantly turn away from him. He was sure she was a Ravenclaw, the only ones that would want to know that other than Slytherins. He kept staring, and internally let out a grim smile to her resistance to turning her face away.
