"That I like Slytherins and I know better than to trust most of them?" he said. "I can't imagine your friend situation is any better than mine," he said with a shrug. "Things have changed, points of view have evolved, at least for some of us. We are left with the baggage of those years."
He chuckled. "You're trying to get rid of me already, aren't you? All right, I shall leave you to it, but only because I simply must make an impression on these poor people after having been deprived of my presence for so long." He turned to go, before stopping. "I'm pretty sure Draco can't wait to see me gone, but I'll make sure to let him know. He gets this look on his face when he hears your name, like the sun and the moon just appeared in his presence. If he ends up having a crush on you, Narcissa will kill you. Something to keep in mind. And before you say something about propriety, my parents were first cousins." He winked at Severus and started to walk away.
