A documentary crew has gathered footage from the past seven years and is finishing up their film called, The Emerald Archer: The Hood and The Rise Of Vigilantism. Some of the footage includes interviews with Quentin Lance, Sarah Lance, Ricardo Diaz, Thea Queen, Barry Allen, Cindy Simone, and Rory "Ragman" Regan.
The documentary crew is in Star City to get footage and finish the documentary now that Ms. Pedowitz finally has the funding she needs.

An angry William yells at Felicity and tells her to take off any encrypted virus or software she's put on his tablet. She asks him if he wants to talk and he asks why they wouldn't let him come home for Christmas break. She tries to explain that things were crazy in Star City but he tells her it wasn't fair what they did to him.
Oliver asks Diggle if he can use ARGUS's security footage and Diggle's help to find the New Green Arrow. He tells Diggle that Emiko is his sister. Diggle and Oliver come to the realization that they have been very distant this past year. Before they can fix that Curtis comes in to help with the security footage.
Oliver and Diggle arrive at the Starling City Atheltic Center to look for their military man and any signs of Emiko. Diggle finds a shrine filled with masks from other vigilantes including Rene's, Roy's, Helena's and Emiko's.
Curtis claims to have found the target who he has christened Kymara. He was heading to 101 Federal Street, which used to be Adam Hunt's building.
Oliver and Dinah warn the camera crew that being with them on this mission is dangerous but they want to stay. Kymara surprises them with bullets and explosives.

William comes over to Rene's to visit Zoe. Rene becomes overprotective when he worries William might like Zoe as more than a friend. Zoe tries to get William to open up but he's unable to.
Diggle tells Dinah about the masks at the hospital and how he hasn't been able to get in contact with Roy or Helena. Dinah and Oliver agree that Oliver attending the mayor's town hall isn't the best idea.
Emiko sneaks out of the hospital and is greeted by Rene in their layer. She tells him that she is Oliver's half-sister and says she didn't want to risk changing things by telling him. Rene assures her it won't change their partnership.
While away from the cameras, Oliver tells Dinah that the New Green Arrow is his half-sister. Dinah gives him the news that Mayor Pollard refused to let Oliver sit out of the town hall.
Diggle comes up with a solution, reunite Team Arrow to assure the safety of those citizens in attendance. Oliver protests the idea at first but Diggle eventually convinces him that it's the right thing to do.

Laurel tells Diggle, Rene, and Curtis that as the DA she can refuse to press charges but there aren't a lot of good options here. All three men assure Oliver that this isn't his fault and it was their decision, and it felt good to reunite Team Arrow one last time.
Felicity comes home and tells William she came across a fake version of his school's website and didn't see any grades or test results. He tells her that he got expelled.
