Heir to the Demon

"Heir to the Demon" is the thirteenth episode of the second season of Arrow, and the thirty-sixth episode overall. It aired on February 5, 2014.

Synopsis
As Laurel continues to unravel, Oliver and Lance try to convince Sara to stay in Starling City and finally reunite with Laurel and Dinah. However, Sara's fellow League of Assassins member, Nyssa, comes to bring Sara back to the fold, but when Sara refuses, Nyssa kidnaps Dinah. Realizing she's putting her family in danger by staying in town, Sara considers re-joining the league.

Plot
The episode begins with a woman at an airport going through security. While her credentials are being checked, an A.R.G.U.S. alert pops up on the computer screen telling the airport guard that there is a security threat. Another guard appears behind Nyssa, telling her to place her hands in the air. Complying, she does so, only to instantly disarm the guard, and take down other security personnel who attack her.

In Queen Consolidated, Moira, with Oliver, Thea, and Walter, is being introduced to what is going to happen now that she is starting a mayoral campaign against Sebastian Blood. In another room, Felicity approaches Walter and states that Tempest had made a monetary withdrawal into Starling National Bank. Walter says he will ask Moira about it, and thanks Felicity for bringing it to his attention. Mark Francis approaches Oliver and says that he will need to withdraw his support from Sebastian, to which Oliver says he will tell him. Oliver then receives a call from Quentin Lance.

Oliver arrives at a hospital room where Laurel, Quentin, and Dinah are in. Laurel refutes her Dad's belief in that she overdosed, but that she merely fell unconscious. A nurse comes in and states that they need to check Laurel's eye, as there could be some hemorrhaging from her hitting her head when she passed out. As Oliver departs, he kisses Laurel on the cheek, and a briefly glances into her "damaged" eye (and seeing a yellowish reflection in the pupil). As they depart, Laurel holds Quentin back, and tells him that she vividly saw Sarah, even though she espouses that she was only hallucinating.

Back at the Arrowcave, Oliver comes in to see Sarah is doing pull-ups on the salmon ladder as Felicity and Diggle watch. Felicity mentions to Oliver that Sarah has been doing that for an hour. Oliver states to Sarah that she saved Laurel's life. She asks how he found her, to which he replies that he would never lose her again. She then says that she has to leave, as the League of Assassins will be coming after her. Oliver tells that her family needs her, including him. He then asks that Felicity retrieve Laurel's blood-work from the hospital.

In a flashback six years ago, Quentin is on the phone with something work related and cooking dinner, as Dinah cheerfully tells him to hang up and spend time with the family. Sarah arrives from college for a 3 day weekend, and is warmly greeted by her family. She then quickly texts Oliver that she has arrived home.

Back in the present, Quentin is sitting at a diner, and Sarah arrives. Quentin tells her that she just can't keep popping up every time one of her family is in trouble, as it's not the way to live, and that she need to face things. Sarah hugs him, and then walks out. While walking down an alley, Oliver watches her leave, and is surprise when Nyssa appears from the roof. She walks towards Sarah with a dagger in her hand. Oliver steadies his bow, prepared to shoot. When Nyssa is close to Sarah, she kisses her. Oliver lowers his bow.
