“The Flash” has introduced a pivotal new character, and at the moment, the only person who knows of Wally West’s identity is Iris, the sister who just found out he existed.
Iris (Candice Patton) is still trying to process of learning that she has a brother (to be played by Keiynan Lonsdale) and her dad Joe (Jesse L. Martin) has a son he still doesn’t know about, but it could all be coming to a head soon.
“You’ll definitely see that come back into play in the next couple of episodes,” Patton told TheWrap.
