Felicity met with Oliver and showed him that somehow Walter had found a copy of the list in his mother's room before Walter had been kidnapped. This didn't sit well with Oliver because he didn't know why his mother would be involved in something like this, like his father was.

Oliver went to confront Moira about the list, and she told him that he needed to drop it and then she burned it. Oliver then went to the foundry where he told Diggle what had happened, and Diggle told Oliver that his mother might be involved in this. Oliver didn't take that well, so he told Diggle to drop it.

Diggle then decides that he is going to drive Moira around for a couple of days and find out what she is up to without telling Oliver about it. He takes Moira to what looks like a restaurant and finds out that it is a friend's party. Later on, he takes her to a building that looks like an office building. While Moira is inside, Diggle sneaks in as well and listens to her conversation through the wall. He recorded what he could of the conversation, and it sounded like she was talking to a man about something called the undertaking and it also sounded like she knew about the Gambit being sabotaged. Diggle would take this to Oliver after he was done with his mission that he was helping Laurel with.

Meanwhile, Laurel is getting the Hood to help her with an prisoner who was released on a technicality. When she meets up with the Hood the cops show up as well, because it just so happens that Quentin snuck a bug in the phone so that he would know where they would be meeting up. The Hood had to use Laurel to shield him so that he could get away.

Oliver then went to see how the defenses for Vanch were. He got through most of it, but he was not able to get to him on that night. Vanch seemed to have someone inside the police because he found out that Laurel knew the vigilante and so he had her kidnapped to lure the Hood out and also because Laurel put him in jail. The Hood and Quentin then decided to work together to get Laurel back. The Hood got passed all of Vanch's men and was about to take him out when he realized that he had used all of his arrows. Vanch had researched the Hood and knew how many arrows he carried so he just made sure to have more men than the Hood had arrows. Luckily Quentin came in and took Vanch down.

Later Laurel and Quentin are talking, and Laurel tell him that she needs sometime because he betrayed her trust. Oliver had also decided that he was not going to work with Laurel again as the Hood because it put her in danger.

Diggle let Oliver listen to the recording he had made of his mother talking to someone else. Oliver couldn't believe it because it sounded like his mother was involved with the people that he had been after since he had come home. Another thing that got him was that it sounded like his mother knew about the Gambit being sabotaged. Oliver decided to go and talk to his mother as the Hood.

"Moira Queen, you have failed this city." Oliver said as he broke in through the window of her office.

"What the hell are you up to mom?" Thea asked.

"I got pulled in once your father was killed. I had to do it to protect you." Moira said.

"You know me better than that mom. I would never want someone else to get hurt because you were trying to protect me." Thea said.

"I know. I just didn't know what to do. Now I know what Oliver's plan is. I will be able to help him." Moira said and everyone else could agree on that.

"Please don't kill me. I have two children." Moira said to the Hood.

"I am not going to kill you." The Hood said as he let his bow down. That was a bad mistake because it gave Moira enough time to get her gun and shoot him.

"Shit, did you just shoot your son?" Roy asked while looking at Moira.

The Hood ended up escaping and found his way to Felicity's car and waited for her to get there. When Felicity got in the car, she heard a grunt from behind her and she turned around to see the vigilante laying in her back seat bleeding. Oliver revealed himself to her and told her to take him to the foundry. Once she got there, she got Diggle to help her get Oliver down to the lair and lay him on the table. Diggle removed the bullet and although Oliver about died a couple of time, Diggle was able to stabilize him. Later after Oliver woke up, he told Diggle to back off of his mom for a while. Diggle agreed but he wasn't happy about it.

Oliver then went over to Felicity and told her Thank you and she told him that she had no interest in joining the team full time but would stay around to help find Walter.

"I can't believe that I just about killed my son." Moira said.

"I think most people would have done that in that situation. You didn't know it was Oliver. If you didn't you wouldn't have shot him." Laurel said.

Thea had just started her community service at CNRI when she and Laurel went out for lunch on day and she has her purse stolen by a kid with a red hoodie. The girls chase after him and they are able to get a chain off of his pants but weren't able to catch him.

It is later shown that Moira and Frank Chen have a meeting to discuss getting out of the organization that the both of them had been forced into. Frank will reach out to the Triad to have them set up the hit on Malcolm Merlyn who ends up being the leader of the organization.

"So, dad is the bad guy in all of this? What is it that he is trying to do?" Tommy asked.

"That will most likely be described later. The why he is doing it though is because he is getting revenge for your mother." Moira said.

"How long has he been planning this?" Tommy asked.

"Since he came back from his two years away." Moira said and Tommy just shook his head.

Oliver is now shown taking out a man on a helipad who is a hitman. He finds out that it was the Triad who had contracted the hitman so he would have to find out who the target was because he knew that this was not over. He later found out that the Triad had contracted another hitman. He found out that they had contracted Deadshot who it turns out was not killed by Oliver earlier in the year.

Later we see Tommy, Laurel and Oliver celebrating Tommy's birthday and Malcolm shows up for a few minutes to give Tommy a gift and ask him if he would come the awards ceremony that he had to go to. Tommy didn't want to go to the ceremony, so he said no. Oliver talks to Tommy and convinces him to go to the ceremony. Oliver later finds out that the hit is going to be on Malcolm at the ceremony. When Oliver gets to the ceremony, everything has already started to get out of hand. The Hood get to the hall and cuts the Triad off and allows Tommy and Malcolm to get up to Malcolm's office. Once they get into the office the window is broken and then Malcolm is shot by a bullet that is soaked in Deadshot's poison. When the Hood gets there, he tries to help Malcolm, but Tommy won't let him anywhere near his dad, so Oliver reveals himself to Tommy and Tommy lets Oliver start a blood transfusion from Tommy to Malcolm to clear the poison from his system. Malcolm later is talking to Moira and says that he knows someone within the organization tried to kill him. Later the Dark Archer will kill Frank Chen.

Later Laurel's mother shows up at her door saying that she thinks that Sara is still alive.

"So, Oliver just saved the man who is behind everything that is going on?" Quentin asked.

"Looks that way." Diggle said.

"Looks like mom is right as well." Laurel said.

"Yeah, no kidding." Sara said.

Tommy is having a hard time reconciling the person that Oliver is now compared to the one before he had gone on the Gambit. He then decides that he will give Oliver a chance and they seem to patch things up a bit.

Meanwhile, Dinah is telling Laurel and Quentin about the evidence that she has that Sara is still alive. Laurel ends up calling a friend in the Chinese Embassy and she gets in touch with the girl who is in the picture that her mother had found. She gets her mother and father to CNRI and introduces the girl to her parents which ends up breaking her mother's heart.

Later on, Thea and Roy seem to be getting closer after she had found his address and had gone there to get her purse back. They were walking down the street and they were attacked by some thugs. Roy ended up sending them all away with the way that he was able to fight. He did end up getting stabbed though. Thea took him to a clinic, and he was scared of needles, so Thea kissed him while the doctor was giving him a shot.

"So, it looks like we turn out to be a couple?" Roy said.

"Looks like it. Hopefully we get to see more of how that develops. Right now, I don't really know what to think about it." Thea said.

"I guess I can understand that." Roy said.

"Thea, there is nothing wrong with Roy. You are obviously a lot like Sara and I. You like the bad boys." Laurel said.

"I guess they don't get any worse than my brother and both of you have had a thing for him." Thea said.

"Hey, I am over Ollie now." Sara said.

"Only, because you know he is loyal to Laurel." Tommy said.

"That is true." Sara said and everyone laughed.
