Surprised by her resourcefulness nature and snarky comments, Andrei couldn't help but let out a dry chuckle of his lips. He wasn't use to being opposed like this, but he certainly enjoyed it. It brought up a competitive side of him he had almost forgotten. More often than not, people let his mistakes slide by simply because of his name or reputation. Which was rewarding at first, but soon it became rather boring. He had to find other ways of entertainment since classes certainly weren't doing it for him. Trouble was mainly his calling, as it diligently followed his side wherever he went. Not like a bad thing, but more like a partner or enhancer of his mood. And when it did not follow, Andrei did his best to stir up something by himself. It seems that this time, he wouldn't even need to lift a figure. It came to him by itself.
"Are you sure we are not related?", he asked through a playful smirk that was on his lips. But now that the fun was over, the true game was about to begin. "No I don't think I'm done with you yet. Let's play a little game, shall we? And see who wins.", he challenged her in a way he knew she couldn't refuse. Slytherins were too proud and vain to let someone else beat them without a fight, even if it was in the most silliest things such as this one. But in order to win, he would need to use his knowledge again.
Being a Dark Follower certainly had it's perks. Beside the reputation it brought, it also gave it's members a large database of files and knowledge that was stored. Obviously, information about people who were possible treats and traitors were kept diligently. From their family, to their personal interest to their love life. Andrei wasn't part of this intelligence gathering team thank Merlin, but those who were did their job quite damn well. Now if he could only remember something about her. Montague, Montague..... There must be something about her, since her name seems familiar from more than just family balls. And then with a grin on his face it finally came to him. "It's quite a burden, being born into families such as ours. Don't you think? A privilege of course, which some take for granted, but a burden nonetheless. How is your family, by the way? I haven't seen your mother and father in a long time. Hope they are doing well. Must be quite disappointing with you though - or do they not know how far you have fallen? Their precious little girl, having been raised the right way, still chose a delusional group of Potter's followers instead her family legacy. Guess that's their sanity off through the window. Makes for many awkward Christmas dinners, don't you think?"
