Did you catch the reference to Wally West in tonight's episode of The Flash?
While Wally West wasn't specifically name-dropped, EP Andrew Kreisberg does confirm the character exists (will be played by Keiynan Lonsdale).
The episode saw Iris investigate her sick mother, where Iris learned her mother left town pregnant and had a son.
That's Wally West!
Another bomb is dropped by Kreisberg in that Wally West is indeed Joe West's son.
“That’s Wally.” In the comics, Wally was originally Iris’ nephew, but Kreisberg said he and the Flash team decided to make it a sibling Iris never knew about, noting, “We always hated on TV shows that it’s year two and somebody’s like, 'Well, Cousin John’s coming!' And it’s like, ‘Oh, good ol’ Cousin John!’ who no one ever mentioned before. It was always weird. The notion that they don’t know Wally was sort of where that came from and then that was the idea that Francine was still alive and then that whole storyline."
"Iris is now in the position that Barry was in last year – she’s keeping a secret to protect somebody and she’s going to find that, for all of her anger at Barry and Joe from last year, keeping this secret is not going to be so easy and it’s going to be weighing on her before she finally decides to take some action in an upcoming episode.”
