Hank and James meet with the company president, Xxx. He assures them that none of his guns have gone missing, and James explains that someone used one of the guns to shoot at a policeman. Xxx suggests that the criminal purchased one of their Heel-14 rifles and modified it with a bump stock. He explains that they manufactured a civilian version and it's distributed as a hunting rifle.

Alura tells Kara that the construction firm has had trouble with the pillar in the past, and Felra was at work when it collapsed. She tells her daughter that it was difficult for her to regain a sense of peace, and Kara says that she's happy to be there and yet she feels unsettled. Kara insists that it wasn't an accident and she has always followed her intuition. Alura says that Kara doesn't have to live as a warrior anymore and it might be time that Kara take care of herself.

The vigilante comes in and nods to Hank, who nods back.

She says that she feels disconnected and that she and Thara are so different after they were so close when they were children. Kara wants Thara's happiness for herself, and says that Mon-El's friendship has made it easier. She hugs him and Mon-El tells her that he came back because Imra asked him how he felt about Kara.
