In the days after the Undertaking Oliver and Laurel tried to give a relationship a try. Oliver ended up not being able to deal with the pain of the loss of Tommy and also failing to stop the Undertaking, so he left Laurel and Star City to go back to Lian Yu to be alone.

"Why would Ollie leave all of us like that?" Thea said.

"He thinks that he failed the city just the way that all of the criminals had, and he thought that the city would most likely be better off with out him." Laurel said.

"Oh, I guess I can see that." Thea said.

Diggle and Felicity end up going to Lian Yu to talk Oliver in to coming back to Star City because of his mother's trial and the fact that Queen Consolidated is falling to pieces and it needs someone from the Queen family there to pick up the pieces. There is a person who is about to get ownership of the company if Oliver doesn't come back.

Once Oliver gets back to town, he hears about the mayor getting shot by a group called the Hoods, who are trying to take up where Oliver left off. Oliver went there that night to check on Laurel who was there because she now worked at the DA's office.

"Are you ok?" Oliver asked.

"Yeah, I am fine. I guess those martial arts classes came in handy." Laurel said.

"I think we need to talk." Oliver said.

"If this is about us, Oliver I can't do that again. You left me and I can't trust you in that way again." Laurel said.

"I understand. I just need to know that you will always be in my life. I don't think I could live without you being my friend." Oliver said.

"I will always be there for you Ollie." Laurel said.

"Well, I better get going. I have a company to save after all." Oliver said and he hugged Laurel and left.

Oliver then goes and checks on Thea who is now running Verdant. They talk about their mother who Thea wants nothing to do with after what happened with the Undertaking.

Oliver goes to QC the next day and meets Isabel Rochev who is trying to take over the company. While they are in a meeting the Hoods come in and try to kidnap Oliver. They do not get him and so later they go to Verdant looking for Oliver again but then they decide to take Thea instead. This finally get Oliver to put the Hood back on and go and save his sister. He saves Thea and then takes the Hoods to where Quentin is and leaves them there.

"You left them alive for a change." Quentin said.

"I am trying to do things differently this time around." Oliver said.

Later Oliver visits his mother and tells her that he doesn't know how to keep the company and she gives him an idea of what to do to save the company. The next day Rochev thinks that she is going to have a majority of the shares for the company when Oliver comes in with an investor who helps him buy 50 percent of the shares. This person was Walter.

Thea goes and visits her mother later because the attack earlier made her see things differently and she wanted to make amends and they did.

Roy is out in the Glades later and he see a woman getting cornered by a guy and he goes to help but he isn't able to take them all on. That is when a new female vigilante helps him out and then leaves.

"Was that you Sara?" Laurel asked.

"Yep, that was me." Sara said.

"That is a cool suit." Thea said.

"Don't you think you are showing off a bit much?" Quentin asked.

"Dad, it distracts the bad guys which helps sometimes." Sara said.

The next day Oliver goes by a hospital in the Glades and when he comes out, he is ambushed by the Alderman, Sebastian Blood, who tells everyone that he is not there to help. Oliver finds out about who shipments of medicine are being taken by the Triad, so he decides that he is going to try and stop them. Roy goes out and tries to help with the medicine, but he ends up wrecking his car. Laurel and Oliver both talk to him to try to get him to stop trying to throw his life away going after the vigilante.

Later when Oliver is going after China White, he finds that she has hired someone to fight the Arrow as Oliver was now called. Ben Turner aka Bronze Tiger and The Arrow fought until the police showed up and they had to run in order to escape.

Oliver then decides that he wants to work with Blood to help the Glades. Oliver sets up a party and invites all of his well to do friends to help with the cause. It just so happens that the Triad attacked when the party was about to start, and Oliver was not able to make it. This causes Blood to talk bad about Oliver in front of his friends and the press.

The one thing that did happen that was good that night was that Oliver was able to stop the Triad and China White and Ben Turner were arrested. Later that night the Arrow goes to visit Laurel, but he finds out that she blames him for Tommy's death, and she has called in the police to surround him.

"I don't understand why I would do something like that." Laurel said.

"I am sure it has something to do with the fact that Tommy died, and you might have seen the Hood there and you blame him for not saving him." Sara said.

"Maybe." Laurel said.

Sara ends up coming in and saving Oliver before he can be taken into custody. Later Oliver talks to Roy and gets him to help with getting intel from the streets.

Oliver gets Roy to try to find out any information that he can on the new female vigilante that is in town. This is where Roy meets Sin, who happens to be a friend of the vigilante.

During the Undertaking some of Iron Heights was damaged and some of the prisoners escaped. Barton Mathis was one of those prisoners. Quentin had brought him down years ago so who knew a lot about the case, but his boss wouldn't let him on the case because he had been demoted because of working with the Hood.

Quentin gets in touch with the Arrow and gets him to help with the case. They finally find the link between the victims and it turns out that it is make up that the girls used. The send Felicity in to buy the make-up and Mathis about gets he but they are able to save her. Mathis does end up killing several girls before they try this though.

Later Quentin and Laurel are both kidnapped by Mathis and he is going to kill Laurel like he had all the other girls. Oliver finds them and saves them. He goes to stop Mathis and the female vigilante ends up killing Mathis with part of her bo staff. After the ordeal is over Laurel realizes that it wasn't the Arrows fought that Tommy died and she starts to blame herself.

The DA is going to try to get the death penalty for Moira because of all the lives lost during the Undertaking. She decides that she doesn't want to fight this because too much will be revealed about her dealings with Malcolm if she does.

It is later shown that the female vigilante is in a fight with a man in a uniform that looks like Malcolm's. She kills the man which will send a message to the leader of the man who had just come after her.

"Me blaming myself like this is not going to be good." Laurel said.

"Why do you say that?" Thea asked.

"I can see myself self-destructing if I go down this path." Laurel said.

"And what are you hiding mom?" Thea asked.

"Just keep watching and you will find out." Mia said.

It is found out by Felicity that the Female vigilante had not been following Oliver like they once thought that she was. She was actually following Laurel. Oliver was able to catch her one night and he was surprised to find out that she was really Sara.

Oliver and the rest of the team are going after a man who has been stealing guns from the army and he gets Felicity to track down the latest stolen shipment by turning the tracking beacon back on. He gets there and tries to take them down but fails.

Later Oliver decides to host a gun drive where people would sell their gun for money. Blood is pleased that Oliver is doing this, and they finally start to respect one another. The mayor as people were calling him, came in and shot up the place, and Sin happened to be hit and Roy and Thea helped her and went to the hospital with her.

Later Oliver gets Felicity to find out when the next shipment of the guns were going out and he then goes and talk to Sara about helping him out. They get to the place where the shipment had already been ambushed. They end up taking the gang down.

Oliver also tries to get Sara to come back to the living because he knows that her family would want her back. She isn't so sure because of the person she has become while she was gone. Oliver is also trying to do this because he nor Quentin can get through to Laurel who is now starting to drink a lot.

It is shown that a policeman who is assumed to be dirty, brings the mayor to where a man in a skull mask injects him with some kind of liquid. The mayor ends up dying from it. The man takes his mask off and we see that he is Sebastian Blood.

"Something always seemed off about him, and what did I tell you about me drinking." Laurel said.

"Yeah, he does seem a bit weird." Quentin said.

Oliver continues to try and get Sara to reveal herself to her family, but she is still reluctant to do so. Oliver lets her stay at the mansion because it is just him there most of the time anyways. While they were there they were attacked by a man from the League of Assassins.

Later when Oliver and Sara got to the lair and were getting Felicity to try and track this man down Sara told Oliver what was really going on.

"I don't know why that man was after me?" Oliver said.

"He wasn't. He was after me." Sara said.

"Why is that?" Diggle asked.

"Have you ever heard of the League of Assassins?" Sara said.

"So, that is where you have been." Oliver said.

"Yeah, I heard rumor of the organization. I just thought they were a myth." Diggle said.

"Well, they are really and one of them saved me when I washed back up on Lian Yu. I was brought back to health and in return I had to serve them. I left after the Undertaking to check on my family and now they are here to get me to return, but I can't deal with the killing anymore." Sara said.

"Well, we will try to help you." Felicity said.

"If they can't get me to go back with them, they will go after my family." Sara said.

"Well, I will track your family down as well as look for this man." Felicity said.

Oliver decided that he would see if Laurel wanted to go to dinner or something. He realized that she had drink some, but he didn't think it was too much. He then walked her home. When they got there Laurel tried to kiss him, and Oliver pulled away.

"Laurel, we can't, you don't trust me in that way anymore." Oliver said.

"Why is it that everyone leaves me. I mean Tommy, my best friend dies. You leave me. Everyone leaves. Is there something wrong with me?" Laurel asked.

"There is nothing wrong with you. I am just trying to respect your wishes." Oliver said.

Oliver then noticed that the door was slightly open, and he went in to check everything out. He found a knife in the wall and he took it down before Laurel could see it. At the same time Felicity was trying to get Quentin to leave town for a couple of days just to be safe. He wouldn't listen to her. Once everyone was back at the base, Oliver decided that he would watch over Laurel and Conner who he had picked up from the daycare and taken back to Laurel's, and Sara was going to reveal herself to Quentin to keep him safe.

Sara and Quentin ended up at the clock tower which was Sara's hideout. While they were there three of the men came in and attacked. Sara took out the leader and Oliver came in and took out another one. They let the last one go with a message to Ras Al Ghul. Sara decided at this point that it would be better if she left town because that would most likely protect her family.

Oliver and Thea then go to the prison to talk to there mother. They tell her that she needs to fight the charges and that no matter what comes out they would still be on her side. Moira agrees to this once her children let her know that they are truly on her side.

"I am really starting to get bad. I mean I don't know why I would give up Ollie like that, but the drinking is really getting bad." Laurel said.

"I am sure that something will happen that will get you straight." Tommy said.

"I hope so." Laurel said.

"I wonder if I come back again?" Sara asked.

"You do and you reconnect with everyone." Conner said.

"That's good." Sara said.

"So, What's next?" Thea asked.

"Well, I think we will reveal a little bit about what happened to Diggle's brother and then we will get to Grandma's trial." Mia said and everyone turned to the screen again.
