At least they all made it back to Earth-1 in the cold open.
When they get back to S.T.A.R.
Labs, though, everything’s falling apart.

And they’re not the only team to finally make it to Central City; Star City’s Mr.
Terrific, Wild Dog, and Black Canary provide much-needed backup as they drive the Nazis out of S.T.AR.
It’s almost just like old times, only with a much more optimistic Cold.
But not everything goes well on board.
We watch as everyone mourns, a moment of calm before the storm.
Sara kisses Stein’s forehead.
Iris breaks the news to Barry.
We even get a lovely shot of Cisco and Caitlin standing together.
Aaaand now I’ve got something in my eye.
Oliver figures that they’ll use Overgirl to threaten Earth-1 and force them to surrender and he’s right.
And so, the team lands in Central City, ready to face down Evil Arrow and his Nazis.
Terrific tosses the Atom for a fun combo.
(After all, Eobard promises him that he’ll be back, perhaps wearing a new face.)
The rest of the hour is devoted to an epilogue of sorts as everyone returns to their respective homes.
Mick cries, too, while Leo encourages him to let it all out.
(Aaaand I think I have something in my eye again.)
Still, that’s not the end of the crossover.
Kara and Alex then go back to their Earth, thanking Oliver and Barry for hosting them.
But still: Stein, guys, Stein.
I repeat:NooooOOOOOOOoooooooooOOOOOOOOoooooooooooooooooooo.
hey join me in revisitingthis clip of Stein distracting everyone in Mission Control with the power of SONG.
