Joanie had a dinner at CC Jitters with her mother, Joe West, Wally West, Iris West and Barry Allen. When asked about school, Joanie explained she would attend Coast City U in the fall, but is undecided about her major. They then discussed about who was a better hero, The Flash or Kid Flash. Joanie thought that Kid Flash was a better hero. Iris revealed to her that Joe knew Kid Flash, and when Joanie asked for his opinion, he couldn't decide which one was better. Suddenly, they were attacked by Clive Yorkin, but Kid Flash "got there" in time and saved Joanie and the others.
Later, Barry, Joe, Cisco, Harry and Ralph went to a strip club and found her dancing there. Joe kindly but firmly discouraged her from being a stripper, to which she responded she was writing a book and condemning male gaze.
