Aaron has been waiting so long to be his own man. Be an adult. Grow up. He was getting a bit left behind what with Adam and Vic being all grown and domestic. Say what you want about Robert. But knowing him and loving him has given Aaron that independence and courage to strike out on his own. Without Paddy or Chas hovering behind him to catch when he falls. Mr Sugden is Aaron's bravest and most mature incarnation.
