After all, neither character is necessarily “young,” which could mean that Rogues return is meant for other characters.
Maybe Weather Wizard is interested in making Barry travel back in time again…
It was teased at SDCC that Season 5 of The Flash would indeed showcase a younger version of the Rogues, although we’re not sure if Weather Wizard and Rag Doll’s presumed alliance plays into that previous announcement.
That may be why this scene was ultimately decided to be cut.
