I actually feel for him a little. It's like having that one sweet high school crush so close to you and you're so close to being able to date her and then one day something happens that wasn't necessarily your fault, but you feel guilty and now she doesn't want to talk to you ever again. (True Story) You can see the effects of the master dictating what goes on in his life and its almost as if Vincent were just a puppet. Is he not able to live independently? Can't he make decisions for himself? Can he ask his master to stop forcing these interactions?
