The Flash Season 2 Spoilers: Everything You Need To Know
11. The Arrival Of Wally West
So, yeah, that new West family member. It's going to be Wally West, who in the comics is originally the nephew of Iris West and Barry Allen. Involved in an accident similar to that of his uncle, he becomes Kid Flash, and later takes on the Flash mantle after Barry Allen's death.
Of all the speedsters he is second only to Barry in terms of speed, and one of the abilities his character has had in the past is that he can 'lend' speed, turning others into speedsters themselves for a period of time, or making them heal much quicker than they normally would.
The show will be putting its own spin on the character, so he won't be exactly like his comic counterpart, but he will at least be a speedster, and related to the Wests, though whether the connection to Barry is made - given he and Iris aren't together (yet) is something to await with interest. One thing we know for certain is that he'll be played by Keiynan Lonsdale, who recently appeared in The Divergent Series: Insurgent.
He won't be the only new West in Central City either, as Candyman actress Vanessa Williams (one of two additions to the cast from that film) will be playing Iris' mother, who was mysteriously missing during the first season.
