Arrow lost quite a few recurring characters: Moira Queen (Susanna Thompson), Sebastian Blood (Kevin Alejandro), and Isabel Rochev (Summer Glau) were killed; Slade Wilson (Manu Bennett) was locked up in an A.R.G.U.S. supermax; Sarah Lance (Caity Lotz) left with the rest of the League of Assassins; and Thea Queen (Willa Holland) left Starling City with her birth father, Malcolm Merlyn (John Barrowman).
