By the sound of the voice coming from the hallway and Alice's panic expression on her face, Andrei could only guess that it was her father coming up to check on her. He couldn't help but laugh out loud at her suggestion, but then quickly covering his lips with his hands afterwards when he realized that he should stay silent. "Don't be ridiculous Alice! It's just your father, not the boogie monster", he said with a chuckle. He got up on his feet and straightened out his shirt. If nothing he could at least make himself more presentable.
"Besides, I work for him remember? Not like I'm not use to seeing your dad around", Andrei said trying to calm her down. He didn't understand the reason to panic. He was just a guy sitting in a girl's room. Both of them were decently dressed and proper even. Merlin knew his own mother caught him in much worse situations than this. Neville might not have liked him, but as he didn't know what was truly going on between them, he posed no real threat. In his mind, all Neville knew was that Andrei was a Slytherin troublemaker which naturally made him worried about his daughter. If he played his cards right, things could very well stay like that forever. Which in the end suited him brilliantly. "Relax, parents love me", he added to Alice with a grin. This was true, but only pureblooded ex-Slytherin parents. He forgot to mention that part.
