"His name is Wally. Wally West," a devastated Iris (Candice Patton) tells her even more devastated father after finally telling him about Francine's (Vanessa Williams) huge secret. Press play on the exclusive video above to watch the heartbreaking reveal go down. Iris cries. Joe cries. We cry. Just so much crying.

Fortunately, fans won't have to wait very long to see Joe and Wally's first meeting as it's set to go down in tonight's episode, with Keiynan Lonsdale set to make his debut as Iris' long-lost brother. (Fun fact: In the DC comics, Wally was Iris' nephew. And became Kid Flash. So yeah, he's a BIG deal.)

"Just like when we met [star] Grant [Gustin] for the first time, we instantly knew Keiynan embodied all the heart and courage of a hero," executive producer Andrew Kreisberg said in a statement after the pivotal role was cast. "We are so excited to be bringing this much-beloved character onto the show."

Not as excited as we are to finally see the West family reunion.

The Flash's winter finale airs tonight at 8 p.m. on the CW.
