I… dont fully understand how that worked, but it was a huge, emotional beat.

(Side note: He doesnt drop the name, but this is totallyBrainiac, right?)

He asks Mon-El to lead the fight and Winn to take his place as the tech genius.

Winn chews over the offer with James.

While going to the future is his wildest dream, how can he leave his family behind?

The distress signal from the witches stolen spaceship interrupts their conversation.

Good thing, too, because the witches and Reign were attempting to restart the cauldron.

She guides Sam away from the waters that would weaken her and toward the fountain that provides strength.

As Sam drinks, Patricia sings a song from Sams childhood.

Sam forgives her before waking up back on Earth, levitating.

Mom, youre super!

Ruby exclaims, and Sam speed-runs out of the room to join the fight against the witches.

And then shes back in Reigns grip, but this time she doesnt allow Sam to land her blow.

When Mon-El pulls them back out, Reigns gone, and Sams 100 percent human.

As he leaves, he tosses her his flight ring, In case you ever need me.

Theyve both walked a path of growth this season, and it yielded a satisfying payoff.

(Lets all just politely ignore the many times Jonn has gone into the field himself, hmm?)

Excellent passing of the torch!

The Danvers sisters end the day at Karas, digesting all the big choices their loved ones just made.

SHOUT IT TO THE HEAVENS, SISTER!

Then Alex asks, Are we gonna be okay?

and Kara assures her they are.

So everything is hunky dory… except for two things.

One is Lena calling Ms. Techsmacher to instruct her to begin the second phase of their Harun-El trials.

Time travel has consequences, people!
