Wally West is ready to give his pops a serious Christmas surprise on The Flash.

'The Flash' Season 2: When Will Barry Head To Earth 2? Grant Gustin Teases A Trip Through The Breach

The Trickster, the Weather Wizard, and Captain Cold will be getting big ol' lumps of coal in their stockings as they attempt to take down the Flash in "Running to Stand Still," but Santa will give the West household an extra special gift when Joe's (Jesse L Martin) long lost son drops by.

As you can see from the photos, Detective West will be floored by the appearance. Iris (Candice Patton) has known of Wally's (Keiynan Lonsdale) existence for weeks now, but as of "Legends of Today," she hadn't let her dad in on the secret.

"Keeping this secret is not going to be so easy and it's going to be weighing on [Iris] before she finally decides to take some action in an upcoming episode," executive producer Andrew Kreisberg told IGN.

Little else is known about Kid Flash's debut. Canonically Iris and Barry's (Grant Gustin) nephew, it appears the speedster's story will play out with a slightly different bent when Wally comes to The CW.

Are you excited to meet Lonsdale's character after all these months? Tell us in the comments below!

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