An earlier clip showed us what was going on with Earth-1, and now we get to see what's going on with the heroes over on Earth-X. I'll tell you that this scene from Crisis on Earth-X definitely has spoilers. So don't go any further if you don't want to know.
The scene shifts to Star City and we see Barry (Grant Gustin), Oliver (Stephen Amell), Alex (Chyler Leigh), Jax (Franz Drameh), and Stein (Victor Garber) following Ray (Russell Tovey) into the Earth-X version of the Bunker and we see Citizen Cold (Wentworth Miller). We find out that Dark Arrow is the Fuhrer and that The Ray is also from Earth-1. This brings up the question again if the upcoming Freedom Fighters: The Ray series takes place before or after these events, and which Earth will he be on when this is over? But at least now we know how they plan to get home — they just have to go through an army of Nazis to get there.
Crisis on Earth-X continues at 8 p.m. ET tonight on The Flash and then concludes a 9 p.m. ET on DC's Legends of Tomorrow.
