Aubert is a rather glum and quiet child who hates it when his parents Baptiste and Armelle yell at each other. He tends to try to avoid Nolwenn as she is always trying to get him to lighten up and he tends to gravitate toward Calixte or Dorian who allow him to be serious and cynical. The latter two will often discuss life with him when he finds them during stays at the palace. Aubert is often trailing after his sister Brigitte, who has been the main person taking care of him in all reality. Aubert enjoys staying with his aunt Arlette, and it is often with her that he can be seen smiling at all.
