Garrick is likely to be the next speedster the show introduces, but it may not be stopping there. Producer Greg Barlanti has admitted that having more of them is something he definitely wants to explore, saying: "That's our hope...and we've already been picked up for a second season so I think if we're going to do something like that, we would do it next season. One of those were very likely to see at some point is Wally West, who starts off as sidekick Kid Flash before becoming the real thing later on. That surname isnt a coincidence either, as he is Iris nephew. The latest comic iteration of Wally is African-American, and Berlanti has stated that the Wests on the show were cast so having a black Flash was a direction they could head in. Expect Wally West to pay his aunt a visit in Season 2, even if he doesnt yet have his powers, or he could make an appearance from the future, although theyd also have to explain her lack of a brother up until this point. Another speedster tipped for a possible appearance is Bart Allen, aka Impulse. With time-travel in play theres a chance he could well travel back from the future he exists in, which should make things interesting between Barry and Iris, as hes their grandson.
