Hearing her talk about her family and her last name, he wasn't surprised at what she was saying at all. In fact, he was counting on it. Andrei knew that before he could even start working with Alice, he had to slowly pull her away from her family. He was sure they were the main reason she was part of the Potter's Army and that whole world that came with it. One of the main perks of being a Dark Follower was knowing this kind of information about pretty much all of the members of PA. They were closely followed of course, because of their tight connections to the Order of the Phoenix. In fact, Alice being friends with anyone from PA was also a problematic thing, but he would deal with that later.
If he could somehow distance her from her family, things would go much easier from there. Anyway, how hard would it be to manipulate a fourteen year old Hufflepuff girl who is out of touch with her family. Quite easy, thought Andrei. The thing was, she could be very good and useful indeed. Is she trusted Andrei fully, Alice could be a valuable source of information not just for him but for all of the Dark Followers. He could only imagine what things she knew or could find out, with her family and friends being who they were. Alice wouldn't know anything about this at all of course. Besides, in his mind, Andrei was only helping a little lost girl finally find her right path.
"You don't have to tell me about that. You're not the only one with a reputation to withhold", he said with a sigh. Something it was difficult being a part of the Dolohov family, but he learned it has brought him more good than bad. "You don't have to do that you know, follow someone's path. Make your own. It's your life anyway. Not your family's. You should live the way you want to. And as for your parents, wear the necklace I gave you. You'll see how well it works.", said Andrei with a wink.
