In True Blood: Authority Always Wins, Alexander Drew's character was great and fantastic, he was aged 9 years before being turned (according to trueblood.wikia). But it also says that he serves the Vampire Authority as a Chancellor.
According to trueblood.wikia:
Alexander Drew is an angelic looking, yet impetuous vampire. He was turned at the tender age of 9, and serves the Vampire Authority as a Chancellor. He enjoys smoking cigarettes and taunting everyone around him, including his fellow Chancellors.
Other vampires such as Salome and Godric are aged 2000+ years. So, how does it possible for Alexander to become a chancellor of the Vampire authority?
