Fatui Harbingers

You get up from your bed and wash your face and go to the dining room and there they are all having breakfast, Dottore reading some of his experiment papers, Pantalone drinking his coffee, Scaramouche drinking his boring bitter coffee, Tartaglia trying to make conversation, Capitan and Pierro reading the newspaper, Arlecchino talking on the phone with one of his children, Columbina was looking at the lost window as always, Sandrone was having her tea and Signora was reading her romance novel

You are Harbinger number 12, they call you by The painter, it is theorized that you are the youngest, is it true?
