The Flash's Future Message In Legends Of Tomorrow To Be Revealed In Invasion Crossover

In the third episode of this season of DC's Legends of Tomorrow, titled "Shogun," Professor Martin Stein and Jefferson “Jax” Jackson discovered a secret room in The Waverider. It appears to be an armory, as it is filled with heavy-duty weapons. While they look around, the lights automatically come on and so does a computer, which has "UPLINK FROM BARRY ALLEN" flashing on its screen. When Jax activates the link, Barry Allen's message begins to play and the screen reveals that it was sent 40 years in the future, 2056.

"Sorry to contact you like this, Captain Hunter, but I can't risk putting any more lives in danger," says Future-Barry. "And neither can you. Which is why you'll keep what I'm about to tell you a secret, even from the rest of your team."

Obviously, there's much more to the message, but it wasn't revealed to the viewers. And even though the message wasn't meant for them, Jax and Stein followed Barry's instructions to the letter, keeping its contents to themselves.

So, when will we find out more about this message? According to Victor Garber, not much longer. “It sort of comes out in dribs and drabs,” Garber told CBR. “It’s a big mystery and a big deal. It’s a spoiler if I give you too much information, but it’s just part of the whole mystery of time travel and the fact that this is coming from Barry years later and then when he finds out — and that all happens in the crossover, so it just sort of unfolds as these things do on these shows, and lots of things occur in that time period.”

STRENGTH AND WEAKNESS — The Legends are still reeling from the news that their time travel-nemesis is a speedster when they are alerted to an Aberration in the Old West. When the Legends arrive they find their old friend Jonah Hex (guest star Jonathan Schaech) in trouble with his arch-nemesis, Quentin Turnbull (guest star Jeff Fahey). 

Cherie Nowlan directed the episode, written by Matthew Maala & Chris Fedak.
