Oliver and Roy are now after Digger Harkness a.k.a. Captain Boomerang. They track him down at ARGUS headquarters where he is trying to kill Lyla. Digger throws his boomerangs, and they are about to make contact with Oliver and Roy when all of a sudden, the boomerangs are stopped by what looks like lightening. They look up to see Barry standing there with the boomerangs in his hands.

Later they end up back at the lair and Oliver see that Caitlin and Cisco have come to Star City as well. While they are in the lair Lyla tells the team that Digger was killed by the bomb in his neck, but it didn't work. Lyla was his superior in this situation, so he wants revenge on her.

Oliver then finds out about a man that will be able to help them find Digger, but he is not cooperative, so Oliver puts a arrow in the man's shoulder and uses it to get the information that he needs. Barry doesn't like the was Oliver is doing this and he confronts Oliver. Oliver tells Barry if he doesn't like how he does stuff he can leave.

Somehow Digger is about to find Team Arrow's lair and he is able to hurt Lyla in the process. He then escapes the lair and is now trying to leave the city. The way that Digger is going to get out of the city is to set up five bombs throughout the city, because he knows that they can't stop the bombs and get him at the same time. Barry seems to have a plan for this though. He speeds a team member to all of the bombs, and they all disable the bombs at the same time. When Digger is caught, Oliver knows that he is too dangerous to be left in a normal prison, so he takes him to Lian Yu to be Slade's cell mate.

Diggle decides that he is going to propose to Lyla because of everything that had happened.

Before Team Flash leaves, Felicity give Caitlin and arrow that was used to kill Sara to see if she would be able to find out who killed Sara. Oliver and Barry decide to have a little bit of fun before Barry leaves, and they start by having Barry run at Oliver while Oliver shoots at him to see if he can stop all the arrows.

"Congratulations, Diggle." Tommy said.

"Thanks man." Diggle said.

"Looks like some of us will be going to a wedding soon." Laurel said.

"Yeah, it looks that way." Thea said.

The League shows up in Star City and gives Oliver two days to find Sara's killer or they will start to kill people until he does. He also finds out that his old friend Maseo went and joined the League after he left Oliver and Tatsu in Hong Kong.

Felicity gets the results back from Caitlin about the DNA on the arrow that killed Sara. The results are really disturbing to the team because it says that Oliver is the person to kill Sara. They end up finding out that it was Thea who had killed Sara and that she had been lying all alone about not know that Malcolm was alive.

Oliver went to confront Thea as the Arrow and get information about Malcolm. Thea ends up fighting the Arrow and escaping. Malcolm confronts Oliver when he finds out that Oliver went to Thea as the Arrow. He tells Oliver that there are substances out in the world that will allow someone to do what you tell them to and not remember it once it wears off and that is what he used on Thea. Oliver tries to kill Malcolm, but he has a video that he will release to the League is something was to happen to him. The only way out of this is for Oliver say that he killed Sara and challenge Ras to a fight.

At the same time all of this is going on Dinah has come to town and she has a feeling that something is wrong with Sara and Laurel tells her the truth about Sara's death. She makes sure that Dinah doesn't tell her father about Sara dying as well.

Later Oliver meets Ras in a specified place so they can fight. Oliver picks his weapon and attacks Ras. Ras is too good for Oliver though and at the end of the fight he ends up sticking the sword through Oliver's chest and then kicks him off the side of the mountain.

"Oh my God! Ollie is dead." Thea said.

"I thought you said he made it for eight years." Laurel said.

"He does. No one said that he was dead." Conner said.

"Ok, I am interested now." Tommy said.

There seems to be a new person trying to take over the Glades. Brickwell is going to try and get all of the criminals released by getting all of the evidence against them and having it destroyed. Diggle and Roy try to stop this, but Felicity stops them. When they get back to the lair, they confront Felicity and find out that she did this because she was trying to save the both of them.

There is a man in what looks to be a League uniform that finds Oliver body and drags him along for a while. He gets him to a house and takes Oliver inside.

Thea tells Malcolm that she is worried about her brother because she had not heard from him in a long time. Malcolm decides to go out and see if he can find anything about Oliver's disappearance. When he gets too where the fight took place, he finds the sword which has blood on it. He took it back to Team Arrow's lair and gave it to them, telling them that it is the sword that was used to kill Oliver.

Felicity then decides that she can't be a part of the team anymore or have anything to do with vigilantism and tell Ray that she is done working on his project as well.

Oliver wakes up to see that both Maseo and Tatsu are looking after him and have been trying to save his life.

Later we see two thugs in a parking lot and a woman jumps down and starts attacking them. It is then seen that it is Laurel who is doing this, finally deciding to become a vigilante.

"Ok, so that is good. Oliver is alive." Sara said.

"Yeah, and I finally become what I need to be to help him as well." Laurel said.

"I am proud that you would want to do this to honor me, hopefully this time around you will do it for yourself though." Sara said.

"That's the plan." Laurel said.

Oliver is still trying to get better so that he can return home. Maseo and Tatsu have to take out some of the League because they came looking for Oliver. Maseo says that he has to go back to the League. This leaves Tatsu there to help Oliver continue his healing.

The team tries to get Laurel to stop being a vigilante. They had to save her that night and they didn't want her to get hurt. Brickwell takes a few city officials hostage tells the mayor in order to get the people back, she will have to take all of the police out of the Glades. One of the city officials is killed. The team is finally able to rescue the hostages. The mayor continues to get the police out of the Glades because she doesn't want anyone else to get hurt. Felicity decides that she wants to come back and help the team. She also decides that she will work with Ray to get everything with his ATOM suit up and running as well.

Malcolm is still trying to get Thea to leave town because of the threat of the League. She somehow convinces him to stay in the city after he had told her why they needed to leave. Word gets back to Maseo that Malcolm is not leaving through the DJ who works at Verdant who also seems to be a member of the League.

"Damn, looks like they really are trying to keep an eye on Malcolm." Sara said.

"Yeah, they are." Tommy said.

"Hopefully, Ollie will get back in time to keep an eye on Thea. I could care less about Malcolm." Laurel said.

"I think everyone is of that same opinion here." Moira said.

Oliver is still on the mend and is really ready to start the journey to get back to his city. Tatsu decides to go with him until she knows that he is safe and won't injury himself any further.

The team is still trying to help the people of the Glades even though there are no more police there to help them. Quentin gives them all of the files that he has on Brickwell, so that it will help them bring him down. While reading through the files they find out that it was Brickwell who was really at fault for Rebecca Merlyn's death. Malcolm has the lair bugged and hears this information as well and decides that he is going to go after this man. Malcolm comes to the team about possibly forming a partnership to stop Brickwell. The team talks about it and they end up saying no.

The team goes and recruits anyone that they know in the Glades to fight against Brickwell with them. Through word of mouth a lot of people showed up to help. Ted Grant tried to take on Brickwell and was badly injured. Malcolm's ends up finding Brickwell and is about to kill him. Oliver talks him out of it.

Later Sin is talking to Quentin and he said something about Sara fighting in the Glades and Sin said that she knew that this woman was not Sara.

Oliver then decides that the only way for him to get any sword experience was to ask Malcolm to train him. Malcolm agrees and he tells Oliver that Thea will have to train as well and that he needs to tell Thea who he really is.

Oliver goes and meets with the team and he tells them that he will have to fight Ras again and in order to do that he will have to get sword training from Malcolm. Felicity was not happy about this because her argument earlier that night was that Oliver would never work with Malcolm and now, he was going to work with Malcolm which went completely against what she had used as her argument earlier.

"I hate to say this, but it is a good idea to use Merlyn for his training." Sara said.

"I agree. He is the only one who has experience with this. How come Felicity can't see this?" Laurel asked.

"Mom is set in her ways and if something doesn't go the way she thinks it should, she will let you know. In this situation her hatred for Merlyn is clouding her judgment on what dad needs to do to actually win this fight." Mia said.

"Yeah, I can see that. You did say that she lets her emotion get in the way sometimes." Laurel said.

"Yes, and this is one of those times." Mia said.

"Ok, so let's get back to the video." Tommy said and everyone nodded.
