Nyssa is back in town with news that will shock Team Arrow: Malcolm Merlyn is alive.
Of course we know that, and Thea knows that, but it's news to everyone else. Even worse, they decide he's to blame for Sara's death.
Whether he is responsible or not, he is Thea's father and Oliver has vowed to kill no more. Will he change his tune if it's proven Malcolm killed Sara? Will it even matter? Surely Nyssa has made no such vow and she's just as angry about Sara.
Laurel will have to come to terms with Nyssa, who she blames for Sara's death due to her involvement with the League of Assassins. That just might happen -- at Sara's grave.
Malcolm's reappearance will certainly throw off the plans of Roy and Oliver as they try to rebuild their relationships with Thea. How will Thea take to Oliver hunting down her father?
We'll also get our first look at Ra's al Ghul when Nyssa talks to him about Oliver. What will she have to say? We'll have to wait to find out.
