## Plot

Oliver remembers the night Laurel died in his dream. He awakens to find Felicity at his door. He tells her ever since Black Siren has become a major enemy, he's been having nightmares about Laurel dying and dreams about her surviving. Felicity tells him they'll find a way to stop Black Siren and put her away. Rene and Dinah awaken in bed after having sex. Rene tells her that Oliver thinks he has gotten him enough hearings to get his daughter back. Dinah congratulates him and asks him how old his daughter was. He reveals she was only 9. Dinah tells him he'll get his daughter back.

At the SCPD, Quentin tries to find a lead on Black Siren only for her to burst in and take Quentin and Thea, who was there to help Quentin. Oliver, Diggle, Curtis, Rene, and Dinah suit up to get their friends back. At S.T.A.R. Labs, Barry and Iris get a meta alert and Barry speeds to the location, however there is nothing there but an empty road and some power lines. Iris realizes what is going on and tells Barry to get away now. He speeds back to S.T.A.R. Labs and sees an electrical surge in the power lines that is heading for him. Barry gets to S.T.A.R. Labs and realizes it was one of the Thinker's metas.

On Earth-38, Kara returns after stopping a bank robbery. Alex, Winn, and J'onn congratulate her only for Winn to see another crime alert being caused by Reign. J'onn tells them he has to meet M'gann so he sends Alex and Winn with Kara. Kara, Alex, and Winn arrive at the location and try to stop Reign. Reign flies away with Alex and Winn and tells Kara to meet her at the docks in two hours or she kills them both. Kara tries to go after them but Reign tells her if she follows them she'll break both their necks. Kara is forced to stay put for now.

The Legends are on the Waverider only to learn of an abberation. They follow it to Africa only to find Gorilla Grodd. Ray tries to shrink it but Grodd smashes the device and takes Sara. The rest of the Legends board the Waverider and try to shoot Grodd but he jumps away. Ray decides to be temporary captain and follows Grodd. Team Arrow finds where Black Siren is hiding and Rene and Dinah rescue Quentin and Thea while Oliver, Diggle, and Curtis find Black Siren. Oliver tries to convince her to stop but she sends Curtis flying with her sonic scream. Oliver and Diggle realize Felicity has been taken but Rene and Dinah have gotten away with Quentin and Thea. Felicity is brought there and Black Siren tells them she is going to have some fun with them.

Barry follows the surge to an invisible hideout in the sky and tries to open it but is shocked by the entrance. Iris tells Cisco and Caitlin to get Barry back. They get him back and manage to restart his heart. Iris is glad that he is okay but they learn the surge is following them here. They prepare for a meta but learn there is no one controlling the surge. They are confused but just as they try to figure it out the building explodes. Kara meets Reign at the docks and she reveals she is making her choose between Alex and Winn. Kara can't make a decision so Reign is about to kill them both when Kara says Alex. Reign snaps Winn's neck. Kara and Alex begin crying but Reign flies away with Winn's body.

The Legends find Grodd and Sara. Ray notes that it looks like King Kong but the rest don't appreciate his joke. Nate and Amaya rescue Sara while Firestorm and Ray stop Grodd. Heat Wave and Isis try to restart the Waverider after it was broken down by Grodd. They manage to restart it and shoot at Grodd. Grodd is distracted enough to let go and the Legends board the Waverider. However, the Time Bureau shows up and the Legends are forced to leave in a hurry.
