As soon as Wally West (Keiynan Lonsdale) was announced as part of Season 2 of “The Flash,” speculation began on how the future Kid Flash would be introduced into the show.

In the comic books, Wally West is Iris’ (Candice Patton) nephew, but as the show stands that would be impossible. The lead theory became that Wally would find his way to Earth 1 from the wormhole, but in Season 2, episode 4, “The Flash” found a way to bring Wally into the action organically. Rather than Iris’ nephew, Wally West is her brother, as Francine (Vanessa Williams) reveals she has a son.

“Yeah, that’s Wally. We always knew we were leading up to this, rather than them suddenly having some cousin that shows up [because] we always hate it on TV shows when it’s year two and someone is like ‘Oh, Cousin John is coming. Oh, good old Cousin John!’ no one ever mentioned before,” says executive producer Andrew Kreisberg at an episode preview event, also confirming that Wally is Joe’s (Jesse L. Martin) son.

While Wally hasn’t physically shown up on the show (and Kreisberg has said previously that he wouldn’t show up until the second half of Season 2, or at least his powers won’t) his presence will definitely be felt through Iris. She’s now the one keeping a major secret from the ones closest to her.

“Iris is now in the position that Barry [Grant Gustin] was in last year. She’s keeping a secret to protect someone 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,” Kreisberg says. “It’s going to be weighing on her before she finally decides to take some action in an upcoming episode.”

Of course, Iris’ secret may take the backseat for a couple of episodes as Barry and his team deal with Wells (Tom Cavanagh) being back in Central City. Episode 4’s cliffhanger left Barry face to face with his old mentor, or the Earth 2 doppleganger version of him, which raises a lot of questions. Kreisberg promises it won’t take long to answer them.

“I think the next episode begins in a surprising way. Obviously this scene will play out but how it unfolds in 5,” he says. “I think the beginning of 5 will give you a lot of answers to questions you’ve all had.”

“The Flash” Season 2 continues Tuesdays at 8 p.m. ET/PT on The CW.
