He hears the door open downstairs, and the sound of a young woman sobbing-her and Vincent talking
It's a teenage girl, eyes wide and panicked. She has deep scratches on her arm and she's bleeding heavily, sobbing. Some books got knocked off of a stand-there are books cluttering nearly every surface in this house-making the crashing noise that Viktor heard.
Vincent: Shh...shhh...I know, I know...it's ok...I promise-he's not going to hurt you again...shh...
He's hugging the girl, not putting any pressure on her arm, comforting her. She gradually calms down
Vincent: Ok...I'm going to treat those scratches for you-you're absolutely sure he didn't bite you, right?
???: Y-yeah...
