Draco/Sirius
Sirius stared at Malfoy dead on for a solid three seconds, near furious at the pure cheek of such hippogriff shit from someone who'd only known Remus for five seconds.
And then a flip switched, and he threw his head back and laughed. "Fuck me, he does like his condescending and protective purebloods, does Remus," he said, the amused light in his eye not entirely unfriendly. "Not intended as an insult," Sirius said, offhand, though he wouldn't be surprised or particularly bothered if he took it as one anyway. "I'm like that myself. I'd dislike me, too, if my new friend's shitty old friend turned up and acted like he owned the place."
A casual flick of his wand saw the chocolates that Draco had recommended fly onto Remus's plate, though Sirius made no move to put back the pewter jug of melted chocolate; it wasn't like there weren't other jugs for others to use. "Making someone laugh is its own kind of kindness, and me acting the ridiculous idiot does it for him more often than not. Take it up with him, if that's confusing for you. How is Narcissa?" He said, without pausing to give a space between these wildly different topics, his wand drawing far-flung foods to add to the pile of James's plate. "Genuinely. I've always wondered if she'd try and make it up with 'Dromeda if she could get away with it."
