Blood is seen talking to a nurse at the home where his mother is being kept. He finds out that Laurel has been to visit his mother. He goes in and asks his mother what she told Laurel and she admits that she told Laurel everything about him killing his father and looking her up in the home so that he would not be caught. He then comes back with the skull mask on and he kills his mother.

Oliver is still looking to find the man that is wearing the skull mask so that he can make sure that doesn't have anymore Mirakuru. He is not having any luck though.

Laurel later comes home and see that police have been going through her apartment and they have found that she has pills, so she is arrested for using drugs.

"I knew that was not going to end well." Laurel said.

"I am sure that you get yourself straight at some point." Sara said.

Roy goes and shows Sin his powers and he decides that he wants to use them to help people. Later that night Sin is being used as bait while Roy goes after the man that is trying to have sex with her and he nearly kills the man because he doesn't have control over himself.

Laurel is kidnapped by the man in the skull mask and Oliver comes to save her. While they are fighting Laurel finds a gun and shoots the man. They take his mask off and find out that it is the policeman that arrested Laurel, Officer Daily. Laurel finds out that the charges have been dropped against her, but the DA's office will not let her work there because of her drug problems and drinking.

Later Roy meets up with the Arrow and he tells Roy that he will train him because he knows how to deal with the Mirakuru.

"Well, I guess I am done at the DA's office then." Laurel said.

"Not necessarily." Conner said.

"I am glad I will finally get to work with the Arrow." Roy said.

"It doesn't go well for a while, but it turns out ok." Mia said.

The next scene shows Ben Turner in prison and he gets a new cell mate. The cell mate starts removing Turner's claws from his skin. Turner then attacks the guards when they come in and check on the other men. He is then able to escape the prison and go and find the man who was responsible for his release.

Later Turner is told what he is going after and he goes to Malcolm Merlyn's mansion. In the basement it is seen that Malcolm had another earthquake machine. Oliver and Roy find them there and try to stop them. Roy loses control and Oliver has to stop him, which allows Turner to get away with the device.

Laurel is seen going to have a meeting with Joanna so that she can get a new job. Joanna lets her know that she can't hire Laurel because she is possibly getting disbarred for her drinking and drug use. This causes Laurel to get even more out of control.

Later Oliver and Roy are going after the device and Oliver finds that the device is in a shipping container. Turner drops in to fight them and Roy gets a hold of Turner and will not stop beating him. Oliver tries to get in the container to stop the device but none of his arrows will work. He ended up having to reveal himself to Roy to get his attention. Roy punches a hole in the container and Oliver throws in an explosive arrow and blows the device up.

Oliver is seen talking to Sara over the phone telling her that she needs to come back and help Laurel out because she is spiraling out of control. Laurel is then seen passing out because she is actually poisoned. Before she loses consciousness, she thinks that she sees Sara.

"Wow, stuff just keeps getting worse for me." Laurel said.

"At least I am on my way back now." Sara said.

"That stuff really does make me strong. I mean it takes a lot to get through a shipping container." Roy said.

"Yeah, it is a little disturbing to know what we will be up against one day." Diggle said.

At the airport, there is shown a beautiful woman of middle eastern decent going through customs. Her passport comes up as a person who is not allowed in the country. She then kills all of the officers and leaves the airport.

Sara is back in town to try and help Laurel with her problems. She finds out that Nyssa is in town. One night she is walking down the street and Nyssa drops down and Sara doesn't know what is going to happen. She knows that Nyssa might kill her, but she ends up kissing her. This is when Oliver shows up and sees them kissing and finds out that they are in a relationship. Sara does tell Nyssa that she is not going back to the League though.

Felicity finds some information on Moira that she thinks she should talk to Moira about. She goes and confronts Moira about Thea being Malcolm's daughter and Moira tells her that she will not tell Oliver about this because it will hurt Oliver too much.

Later while at the hospital with Laurel, Dinah is kidnapped by the League and will be killed if Sara doesn't go back.

Moira is about to have a news conference where she is going to announce that she is running for mayor. Felicity brings Oliver to the side and tells him about Thea being Malcolm's daughter, which makes Oliver mad, and he tells his mother that he will support her campaign but will not be a part of a family with her anymore.

Sara then goes to save her mother. When her mother is free, she takes some poison so that she will die and not have to go back to the League. Oliver comes in and fights Nyssa and he then goes and gives Sara the cure. Nyssa releases Sara because she knows that Sara would rather die than go back to the League. Laurel shows up once this is all over and see that Sara is alive and she doesn't take that well. Later they are at Laurel's apartment and Laurel yells at Sara and tells her to get out.

Later Oliver and Sara are in the lair and they are talking. Sara tries to see about starting a relationship with Oliver. "I would say no because I know that it would most likely piss Laurel off if we got together, but she did tell me that she couldn't trust me anymore in a relationship so I guess we could give it a try." Oliver said. The two then kissed and had sex.

"That's not going to go over well." Thea said.

"I doubt it either. Although, I wouldn't try that now because I know Laurel is going to go after him when he gets back." Sara said.

"I don't blame you in the old timeline. I did tell him we couldn't be together. But you are damn right he is mine in this new timeline. By the way, what the hell is Felicity doing telling Oliver that, when she knows that it is just going to make things bad for everyone." Laurel said.

"I was wondering the same thing. That was kind of stupid." Sara said.

A man named William Tockman is giving instructions to men who he is having rob a bank. He has everything timed out and one of the men makes a mistake and ends out endangering his operation. Tockman ends up getting something called the skeleton key that can open anything.

Later Oliver and Sara go after Tockman and his people when they rob a bank. Tockman sets it up so that a train is on a collision course with a bus. He doesn't realize that there are two of them there, so Oliver goes and stops the bus while Sara tries to stop the robbers. She throws a part of her bow staff and gets some of Tockman's blood on it. They test it and find out that he has a disease.

Later the Lances are having dinner at Laurel's apartment. Oliver shows up with Sara and Laurel finds out about them being together. She gets up and storms out of the apartment and Oliver follows her. They end up having a fight and Oliver says that he is not going to chase her any longer and that she is going to have to help herself if she is going to get any help.

Felicity is looking into Tockman and he ends up getting into her computers because of the skeleton key and ends up blowing them all up. Felicity has been feeling like the odd man out now that Sara is a part of the team, so while she is trying to fix the computers, she has an idea to go to a bank and try to stop Tockman from stealing anything from there. Oliver, Diggle, and Sara get there in

time to help her. Diggle goes down to the basement to stop the gas from exploding. Sara and Felicity are in a room and Tockman aims at Sara and shoots his gun which Felicity jumps in front of, taking the bullet for Sara while Sara takes Tockman down.

Later Laurel is seen entering Verdant and she talks to Sara who is working as a bartender. They reconcile and then we see Laurel going to an AA meeting with her father.

"Looks like Ollie finally talked some since into me and I got my sister back." Laurel said.

"He seems to be pretty good at that." Sara said.

"Yes, he does." Quentin said.

Oliver goes to his house because Thea sent him a text telling him to come by the house. When Oliver walks in he sees his mother in the living room talking to someone. Moira introduces the man as Slade Wilson. This is not something that Oliver was expecting, and he was shocked that Slade was alive, and you could see it on his face.

Slade is there to help fund Moira's campaign. Moira leaves the room and Oliver tries to stab Slade with an ice pick. Slade block him and Oliver drops the pick. Thea then comes into the house and Moira talks her into giving a tour of all the painting in the house. Oliver dials a phone number and let it ring and when Felicity picks it up, she puts it on speaker and Sara realizes that Slade is there.

The team leaves and arrives at the mansion with Diggle getting into a sniper position. Sara went in through an upstairs window and Roy went in the front door. Roy got everyone's attention walking in, then Sara came down the stairs surprising Slade, because he thought she was dead. Now Slade knew that Oliver had backup, so he decided to leave. On his way out Oliver walks with him and he tells Oliver that he is here to keep his promise and then he leaves.

It is later found out that Slade planted cameras all over the house so that he can spy on Oliver and everyone else.

"This is not good at all. Slade is not going to be easy to stop with Mirakuru in his system." Sara said.

"I am sure Ollie finds a way though." Thea said.

"I hope so." Tommy said.

Amanda Waller is now seen walking down the hall of ARGUS to get to an office. When she enters, she sees that all of her people are knocked out and she sees Oliver standing there in his Arrow suit. She asks what he is doing there, and he tells her about Slade. Waller then tells him about a man that they have been tracking named Deathstroke and we see a picture of Slade in his armor.

"I do have to say that his suit is pretty cool." Tommy said.

"Yeah, but it won't be cool to go up against him while he is wearing it." Sara said.

"Let's go take a break and then we can come back and watch what happens next." Conner said and everyone got up and went to the break room.
