Hol' up, so the guy who's been saying to change the portraits isn't the one who actually made the decision? I thought the assassin agreed to kill the person responsible, not just any guy involved.
@Malte I think the artist did provide the name of who she wanted killed, it's just that further dialogue seemed to have become less specific. I was just trying to sort out whether it was the case that the person that the artist named, whom she thought was responsible, actually was getting orders from someone else.
