- —Malcolm Merlyn tells Oliver about the Lazarus Pit
|Ra's al Ghul finally makes Oliver an offer he can't refuse. The team joins Oliver on his journey to Nanda Parbat where a heartbroken Felicity decides to take matters into her own hands.|
The episode opens with Thea on the floor, clinging to life after Ra's' attack. Oliver gets to her and rushes his sister to the hospital. Thea briefly flat lines, but doctors are able to bring her back. Later the doctors tell Oliver that while Thea is technically alive, she may not ever regain consciousness and asks him to consider taking her off life support. Malcolm arrives at the room and weeps at Thea's side.
In our Hong Kong flashback Oliver, Maseo, and Tatsu watch General Shrieve arm the bioweapon.
Diggle and Felicity arrive at the hospital and try to comfort Oliver. He looks out the window and sees purple smoke. He tells them "He's won." Oliver goes to Maseo, who tells him that if he becomes the next Ra's, the current Ra's will save Thea. There are apparently special waters in Nanda Parbat that can bring back the dead. Malcolm says that if even if Thea is brought back to life, she will be fundamentally changed.
Felicity asks Palmer if they can use his jet to bring Thea to Nanda Parbat. He tells her that he now realises she still has feelings for Oliver. She doesn't deny it.
Against Malcolm's wishes, Oliver, Malcolm, Diggle and Felicity head for Nanda Parbat in Palmer's plane.
In the flashback Queen, Maseo and Tatsu pursue the truck carrying the bio weapon in a stolen car. He and Tatsu take control of the truck but find the weapon is missing.
The party arrives at Nanda Parbat and find Ra's and the entire League waiting for them. A ceremony begins and Thea is lowered into the waters. Within moments she comes flying out, acting almost like a wild animal. She is sedated and Ra's tells Oliver it's time for him to fulfil his end of the arrangement. When Thea wakes up she doesn't recognize Oliver, but she immediately calls Malcolm "Dad." Both Malcolm and Felicity think what they've done is wrong.
Felicity tells Ra's she and her friends are not going to let this happen to Oliver. Ra's tells her that she needs to tell Oliver how much she loves him, followed by "good-bye."
Felicity tries to remind Oliver how much good he's done, followed by expressing her love for him. They kiss and begin to undress.
In the flashback one of Shrieve's men tells them the weapon is in a food cart.
Felicity and Queen share a drink. She immediately apologies, and Oliver loses consciousness. She says "I can't lose you. I won't." Diggle and Malcolm think she's made a huge mistake, and there's no way they can get out alive. Malcolm suggests their only chance is through the catacombs. As they fight their way out, Maseo decides to help them by suggesting the best way out. They end up surrounded by League soldiers, but Oliver gets them to stand down by telling them he's the heir to Ra's and will return. He put the rest of them on the plane and says he must stay behind.
A confused Thea wakes up the next day and Malcolm explains what happened with her brother and the League. Felicity is tasked with telling Laurel that Oliver will not be returning.
Oliver warns Ra's to leave his close friends alone. Maseo then confesses to helping Oliver and offers Ra's his life. Ra's spares him, in part because Oliver will need him during the transformation process.
In the flashback, Oliver, Maseo and Tatsu end up in a huge fight in the market. But ultimately the vial is launched up in the air and smashes into the ground.
A cleansing ritual to wipe out Oliver Queen's past begins. He is given a large brand on his back. Moments later we see him in the garb of a League of assassins member.
