Previously, Nyssa al Ghul returned to Starling in search of Sara. After learning of her death, Nyssa swore a blood oath to avenge her. Nyssa revealed Sara was in Starling to confirm rumors that Malcolm Merlyn was alive, leaving her and Oliver to believe Merlyn was her killer. However, when Oliver confronted Merlyn, Merlyn convinced Oliver of his innocence by swearing on Thea’s life that he hadn’t killed Sara.
