Vincent had taken you. He wanted you all to himself, and the only way he would achieve that, is if he kidnapped you. And that's exactly what he did.

Vincent looks into the mirror, he has blood all over his hands because he had murdered someone who had hurt you weeks ago. He rubbed his cheek with his right hand, getting the blood on his cheek, and it dripped down.

"My sweetheart would come around eventually..." Vincent mumbles to himself. He starts to think of checking up on you.
