Iris: You are really all about the speed, huh? Wally: Yeah, its what I love. Airplanes, cars...running? The show has been pretty on-the-nose already about Wally West's need for speed, and doubled down on that this week. Even people with no idea about the character's backstory from the comics must at least be getting the hint of something happening to the newest member of the West clan. This week proved that he's ready to become a more permanent fixture in their lives, with a nice scene between him and his hospitalised sister. But what about him becoming a speedster? The hints are there, and with that name he's surely going to happen, so the question is how, and when?
