Stephen Amell says that the upcoming sixth season of Arrow will focus more on family than legacy. The CW?s flagship superhero series concluded season 5 last week, which united series veterans ? Nyssa al Ghul (Katrina Law), Malcolm Merlyn (John Barrowman), and Deathstroke (Manu Bennet), as well as Captain Boomerang (Nick Tarabay) ? in a conflict with newcomers Prometheus (Josh Segarra) and Talia al Ghul (Lexa Doig), among others. The writers and producers sought to conclude one chapter of Oliver Queen?s (Amell) story arc with the finale episode, titled ?Lian Yu?.
