Just look at the way they take down the Legends in the first five minutes of the episode.
Heywoods grandfather) and oh, right!
the Legends have a go at explain theyve met Rex (a.k.a.

Hourman) before, when he warned them in the season finale to stay away.
Rex finally decides to give them a shot, but it comes at a cost.
He immediately assumes Stein is the leader, completely passing over Sara, who tries to take command.

Of course, the missions not as easy as they all think itll be.
They finally agree to leave the past behind, once and for all.
Well, not so fast.
Sara says maybe Commander Steel isnt all Heywood thought he was, but he doesnt think so just yet.
He feels around his neck for the dog tags but gasp!
theyre gone…which means history has changed, certainly for the worse.
Without the dog tag heirlooms, it means Commander Steel must have died at some point in history.
Thats not the only issue over which the Legends are butting heads.
Just when it seems all hope might be lost, a bright light flashes through the room.
Its Stargirl and the rest of the JSA!
We came to rescueyou, Stein says sheepishly in response.
NEXT: The clocks ticking…
Sara, meanwhile, also points out Heywoods struggle.
(I mean, the League of Assassinswasdark.)
Amidst all this, at least Sara and Rex are able to keep their heads on straight.
After that, the teams finally head to save Vixen and Ray.
The latter angers Krieger, but stalls long enough to take out two Nazi guards to make it escape.
Outside, Commander Steel captures the serum-ed up Kriegers attention and tries to run away.
One takes out Krieger, but one also lands near the pair, leaving Heywood grievously injured.
… At least, until his powers manifest next week.
Anyway, at least everything worked out, right?
He prevents Rex from ever moving forward in the timeline.
Hes discovered by Vixen and manages to gasp time traveler to his teammate before he dies.
Midnight, among the other JSA members largely ignored by this jam-packed hour.
