Zoe, you are an actress and that is your job and you did it great. No need for apology please. Never apologize for doing your job, but feel proud that you were considered for it. You have a wonderful mix that gave you that beautiful "mulata" color that combined with your talent and reputation, earned that role, so my darling, own it! And don't let anything or anyone tell you different. Acting is an art form that interprets, conveys, messages, history, stories. Be proud, you are a great artist. You didn't step on anyone's toes.
