As a guard attacks Arrow, Faust comes out on deck and activates a missile launcher. He tells Arrow that next time, the mayor should pay. Faust fires the missile, and Arrow takes down his man and pins Faust to a scaffold. The crime lord warns that Arrow can't disarm it, but Arrow says that he has a friend who can.
On a rooftop, Mr. Terri throws one of his T-Spheres at the missile. It spoofs the guidance system and draws it back to the water, where it explodes over the harbor. Faust tells Arrow that he looks troubled as if the detonation stirred unfortunate memories.
Oliver tells Felicity that there's an Argus supply ship on the other side of the island and Slade knows where it is. Slade heads off on his own, figuring the others won't make it, and the others head for the plane to take shelter. Samantha goes off after William, and Thea goes after her. The bombs go off, and Diggle lags behind.
At the HQ, Rene gives Oliver a speech he wrote for the police academy graduation ceremony. Felicity comes in with fast food and says that he had to put her mother on a flight to Las Vegas. Oliver says that he's going home, and the three men leave Oliver with Felicity. She says that she got food for William, and Oliver asks her to come with him.

He mutters that school is fine, and Oliver suggests that they go to a baseball game. William says that he's tired and going to bed, and they say good night to each other.
At the station, Dinah questions Faust and asks where he got the muscle. She applies some pressure to his wounded shoulder and figures that someone paid Faust to launch the missile. She goes to get some water, and an officer tells her that Quentin's appointment as deputy mayor was an hour ago and he hasn't shown. Dinah gets a text from Quentin and says that she knows where he is.
Quentin is sitting in a bar looking at three glasses of whiskey when Dinah comes in. He thanks her for coming and says that he can't tell his sponsor what happened. Dinah tells him that Laurel wouldn't have wanted him to start drinking, and Quentin wonders which Laurel.
The officer gives Faust a can of pop and opens it for him. Faust slams his head into the table to knock a tooth loose, pulls it out, and explains that it's a C4 implant. He drops it into the pop can and it starts fizzling. The C4 goes off, and Black Siren comes in and tells Faust that he's right on schedule. She's brought mercenaries with her, and they open fire on the other officers. Alex activates a bomb and says that they're all set, and gives the remote to Black Siren. She sets it off as they leave, the station blowing up behind them.
The next day, Oliver, Quentin, and Rene look over the debris. Quentin suggests that they delay the graduation, but Oliver refuses to give in to terrorism. Dinah shows them video of Black Siren and assures them that she got to it before anyone else could see it.

That night, Black Canary intercepts Black Siren's van and uses her sonic scream to stop it. Black Siren gets out and the two of them unleash their sonic blasts on each other.

He tells her that they have more pressing business, and Felicity explains that she identified the targeted areas at city hall. They wonders why Black Siren is attacking the graduation, and Quentin comes in and says that Black Siren didn't get him. Dinah tells him that he doesn't have to do it, but Quentin says that he's been living with the guilt too long. He explains that Black Siren wasn't dead when they found her.
Quentin shoots Black Siren before she can cut Dinah's throat.
Dinah says that she told Quentin to tell them that Black Siren was dead when they found her. She points out that Black Siren was going to kill her and Quentin saved his life.

Felicity reports that they've found something and figures that something is wrong. They check in with Diggle, just as a grenade rolls in. It goes off, stunning him as he takes cover, and Black Siren and his mercenaries come in. She tells Felicity that Diggle is fine and going to catch up with an old friend. She figures that Diggle lost his arm, and he slides a flash bang over to her and the others. He slips into the shadows and the mercenaries go after him while Black Siren tells Faust that it's time to go to work.

Quentin says that he is and apologizes for lying, and Oliver assures him that it's okay.
The next day, Oliver visits Rene at the hospital. He asks what would happen to Zoe if something happened to Rene, and Rene points out that his daughter has a new family.

However, Oliver warns that finding one's son doesn't always go as planned. Slade tells him to be patient with William, but to also be prepared to choose between being a hero or a father. He explains that the two of them walk between two worlds, but they can only do that so long. Slade shakes Oliver's hand and wishes him luck, and leaves.
At the bunker, Diggle is checking his injuries from Lian Yu. Dinah comes in and asks if he's okay, and offers him his gun. She confirmed that Diggle didn't fire it, and gives it to him.
