But first, Barry.

Gorilla Grodd has arrived in 1979, and hes intent on killing Obama before he ever becomes a politician.

Im guessing someone stopped them from giving Grodd a red hat and all.)

They then wipe Barrys memory clean, and back to the overarching plot they go!

And that overarching plot hasreallyheated up.

Meanwhile, over in Zambesi, Amaya is rejecting help.

She wants to get rid of the warlords, and she tells the men to stay away.

Well, maybe not so fast.

The young Amaya is still around, and shes sure she can talk Esi into accepting her fate.

to Kuasa…) and explains that they now have a common enemy.

Without any others to turn to, Sara seeks out Obama again, hoping for more insight.

He agrees, but now what?

Now…enter John Noble.

But he does so anyway, only after chiding the script for being crap.

But its no use: Mallus simply tells Damien that Nora is as good as dead.

Damien then has an even tougher conversation with Sara.

He tells her that he regrets everything hes done, that he wishes he could take it all back.

He even apologizes for killing Laurel, because back then, he didnt know what love meant.

He even compliments Sara, telling her that she overcame all that darkness to find love again.

If only he know how much of a struggle that love has been.

In fact, shes the12thAva hes used.

After all that, though, they still havent come any closer to preventing Mallus from escaping.

or else Mallus will be freed.

Hasnt fixing history taught them to learn from it?

Now all they have to do is double-check Zambesi falls and to arm themselves.

Esi waits for the warlords, while Ray and Wally inform Amaya and Nate of the plan.

But Damien, thats not Nora…not anymore.

Still, Daddy Darhkest cant help himself when the hour comes to help the Legends in their final step.

He discovers through headlines that Zambesi was still destroyed but not by warlords.

It was destroyed by Grodd.

But again, its all too late.

And now that Noras freed, so too is Mallus.

Stay strong, Sara!
