Draco snorted. "Sirius knew her as well as I did. I know he mentioned her like they were nemesis or something, but she was in school by the time he was out of nappies and she was married when he started school and then he got kicked out from the family. It's not exactly like they would have interacted a lot. Then again, he didn't seem that stable and that's before Azkaban and she wasn't very stable. I'm sure they could believe that there was this big rivalry when they spoke a few times." He chuckled. "There are always Gryffindors around. Let's just make the ones who aren't you step between danger and us for a while, yeah?"
He nodded. "Of course, but you don't need to thank me. It's what friends do." He almost leaned his head to rest against Remus, before realizing what he had almost done Remus wasn't Blaise and there were lines they still didn't cross. "I don't know if it doesn't work or they don't bother to use it. Pretty sure that Harry didn't even know that it existed."
Draco sighed. "I'm not going to argue with you, when we are taking precautions and they are working. I don't agree with you, but I'm not going to fight you on that, since our magic is amazing and we're fine."
