Oliver is joy riding on his motorcycle when he receives a call from Thea about his lunch with his mother. Oliver doesn't want to go, but Thea tells him to just meet up with her. At Queen Consolidated, Paul Copani and Moria exit the building while Paul reveals his business proposal. She doesn't want anything to do with it. When she notices Oliver park his bike across the street she uses his presence as a reason to get rid of him.
Suddenly, another motorcycle speeds by and opens fire toward Moria and Paul. Paul is killed, Moria is knocked down. Oliver rushes to his mother's side to make sure she is alright, then rushes off after the motorcycle. As he is running, he grabs a piece of rebar and when he is close enough to the bike he throws it at it, but misses the killer. A few trucks suddenly block his path allowing the cyclist to escape.
Moria is at the hospital, but she only has a concussion. Dr. Lamp announces that she can leave as long as someone stays with her to make sure she is alright. Oliver says he is sorry for running after the bike, and that he did so to try to get the licence plate off of it. She tells him that it was foolish, and they hug.
As Oliver leaves the room, Thea approaches him. She is very upset that he left Moria and tells him he isn't much of a hero and that she knows that he is lying about it. While she is heading back to their mother, the detectives arrive. Oliver asks if they found the shooter yet, but they are still looking. Quentin also reveals they believe that she wasn't the target since Paul Copani had deals with the mob.
Laurel is working from home when she hears a knock at her door. She is greeted by two smiling faces, a man who has arrived with her pizza she ordered, and Tommy with takeout from Toro's Sushi. He suspected she would be working late and hungry, so brought over some food. He also asks her to go out with him for dinner. He admits that their relationship is going in the wrong order, but he would really like to just have a dinner with her at a restaurant.
At the Arrow's hideout, Oliver is practising on a Wing Chun Dummy when Diggle arrives and tells him he should take time off since his mother was just attacked. Oliver reveals that Copani was the target and that he isn't the first member of Bertinelli's crew that has been attacked. He wants to go undercover to find out who is after them. John tells him he should be concentrating on his family instead. Oliver tells him he tried that and that his family doesn't understand since he has to keep lying to them about what happened. The only way he knows how to protect him is by finding the shooter.
The shooter drives into a building on the motorcycle and approaches a white board filled with photos of Bertinelli's organization. Copani is crossed off, then the killer removes the helmet revealing it is a woman.
Thea is about to leave the mansion when Oliver stops her. He tells her that he needs to leave for a business meeting and asks her to keep watching over their mother. She is upset with him since she has been doing that all day, but agrees anyway. Tommy also shows up, complements Thea on her dress, then reveals to Oliver his dating plans. Oliver tells him that they both deserve someone special, but he has got to run. He also jokingly warns him not to break her heart.
Oliver arrives at Frank Bertinelli's, who immediately introduces Oliver to his "business associate" Nick Salvati. The woman who was riding on the motorcycle walks by them on the 2nd floor.
Thea and Moria are sitting in a bed talking about Oliver. Thea tells her that she isn't happy with his attitude and lies. Moria states that everyone has lies that they want to keep for themselves, and reveals what Dr. Lamb told her about the Oliver they found may not be the same one they lost. She tells her that they need to stop judging him for who he was and accept him for who he now is.
Frank hands Oliver a glass of whiskey and tells him he is surprised that Oliver is involved with his family's business. As Salvait gets a call and heads to the next room, Frank announces he wants the contract to build the new the new division.

Frank takes Helena into an adjoining room to ask her to take Oliver out for dinner to secure the deal. Helena doesn't want to, but he pushes her on, then tells Oliver that Helena will continue with the meeting. He is disappointed that he can't continue dealing with Frank, but accepts anyway.
At a construction yard, Frank and Nick meet with China White and Zhishan. He believes that they are attacking his gang, but she tells him they aren't responsible. He doesn't believe her and tells her that there will be a war if the attacks don't stop. As the others leave, Nick tells Frank that the Triads may not be responsible, but Frank still thinks they are.
Quentin and Hilton have listened to the conversation with the bugs they have left at the scene. Quentin believes that the killer isn't a professional since they aren't accurate enough with guns, so it likely isn't the Triad. He also rules out Arrow since there are no arrows left at the scenes. He figures if there is another attack they will have a mob war on their hands.
Helena takes Oliver to Russo's, a restaurant favorited by Frank. Once alone, she asks Oliver why he is doing business with her father so he asks her if she believes in her family's business. She points out that she shares the name only and they have already made judgments against each other from their families' names. She asks if he was happy being alone on the island, and Oliver admits there were days he did.

Oliver and Helena are still on the topic of his time on the island and how it changed him. He comments on the cross around her neck and she tells him that it was a gift from her dead fiancé, Michael.
