Arrow, Speedy, Nyssa, Spartan, and Roy go to the warehouse at the address. They set off a trap and narrowly avoid it, and Nyssa figures that they're close. Nyssa sets off a bomb with magnetic powder attracted to the same metal that Ra's put his relics in. The powder indicates the spot in the floor where the box is hidden, and they realize that its lock is encrypted.

Nyssa calls Oliver "husband", and he points out that Felicity doesn't like her saying that. She says that Thea must find her own truth, and Oliver says that Thea shouldn't be charged with righting Malcolm's wrong.

She uses a scanner on the paper to duplicate it digitally, and tells Nyssa not to distract her. Nyssa doesn't take the hint and calls Felicity "sister wife".
Thea finds Roy, who wonders why she thinks that it's her responsibility. She says that Malcolm died for her and she feels like she can't run away from it. Roy figures that they're running toward something, and points out that she keeps finding excuses to stay. Thea assures him that Roy is her future, not the map.

Oliver tells Thea that the team will stop Athena and Thea can go with Roy. Thea points out that Oliver was going to retire but hasn't, and Oliver admits that he doesn't know why he came back.

Thea tells him that being Arrow makes him feel complete, and Thea hopes that she'll be the best version of herself as well.

The team goes to the plant and Overwatch detects an energy spike indicating that they've activated the bomb. Thea calls on Athena to come out if she wants the map, and Athena and the assassins step out. Athena says that the map is meaningless without spilling Thea's blood.

Athena knocks Thea down and says that she's won. Thea threatens to burn the scroll, and when Athena goes for it Thea stabs her in the stomach. Nyssa arrives and they realize that Athena has slipped away. Thea says that she would have burned the map, and realizes that the blood from her cheek has brought out the hidden writing on the paper. Nyssa realizes where it leads to.
At the bunker, Felicity says that Malcolm used bleeding-edge technology to create the map.. The maps show ley lines that intersect on three spots on map. Nyssa says that there are three Lazarus Pits. Disgusted, Thea walks off and Oliver advises Roy to give her some space.
The next morning, Curtis goes to the situation and finds Anastas. He asks the officer out on a date and Anastas agrees. Once Anastas goes, Dinah comes over and Curtis says that he's getting back in the saddle. She tells Curtis that there aren't any Vertigo cases because Hill released all of the evidence. They figure that Diaz is pushing Vertigo.
At the apartment, Thea apologizes to Roy for storming out. He wonders if she's going with him or Nyssa, and Thea tells him what she discussed with Oliver. Thea figures that she could right her father's wrongs, and Roy tells her that he'll go with her so that they're together.
That night, Oliver says goodbye to Thea and tells her to call him. Roy says that he'll keep her safe, and Nyssa says that Thea needs less protection than Oliver thinks.

They hug and Thea assures Oliver that he'll always be with her.
