Wally West is coming to town!

Keiynan Lonsdale will make his debut on Tuesday’s episode of The Flash, which will definitely shake things up since Iris (Candice Patton) has been keeping the fact that he’s Joe’s (Jesse L. Martin) son a secret — though based on the first-look photo above, that won’t last much longer.

Destined to become the speedster known as Kid Flash, Wally is just an ordinary teenager when he’s introduced. “I would liken Wally coming in to the way we brought on Colton Haynes on to Arrow,” executive producer Andrew Kreisberg previously told EW. “Just like with Colton Haynes, who eventually one day put on the Arsenal costume, I wouldn’t be surprised if one day Wally West becomes Kid Flash.”

“Part of the season is watching Barry mature and grow up not just as The Flash, but as Barry Allen,” Kreisberg continued. “Suddenly introducing him to a bit of a wayward kid who has some attitude problems and some authority issues and is quick with a sassy remark — all of which is very Wally West — and then watching Wally integrate into S.T.A.R. Labs universe, but also just the world of these characters, is going to be a lot of the fun of the back half of the year.”

The Flash airs Tuesdays at 8 p.m. ET on The CW.
