The episode begins with Octavia and Bellamy saying their goodbyes over the radio.

Bellamy tells her shes already succeeded at bringing about unity when neither he nor Clarke could.

Clarke comes in and realizes she wont get to say goodbye to her mom.

Back at the bunker, Octavia comes out to greet her people.

From the ashes, we will rise.

The bunker begins shaking and thats the last we see of them.

Over in Beccas lab, they watch the death wave from their lone drone feed.

Polis burns to the ground in seconds and then the feed cuts out.

And the clock starts ticking…

While everyone gets to work, Clarke and Bellamy have a little H2H.

But even then, every stupid thing you did, it was to protect your sister.

She didnt always see that, but I did.

Youve got such a big heart, Bellamy.

Ive got you for that, he tells her.

But shes clearly not so sure.

Hes able to get the rig, but his hands suffer extreme radiation burns.

Murphy grabs it by himself and leaves Monty behind.

Back at the lab, theres a small explosion in the spaceship.

She was saving them long before she had the bit of AI in her brain.

And thats all she needs to solve it: Alie transmitted herself to the ring through the satellite towers.

(Anyone else concerned that Alie may still be in the ring?

Or is she definitely dead everywhere?)

And its lucky they do because they see Murphy walking alone.

Raven tells her shell need 10 minutes to get from the satellite to the lab.

(Recap continued on page 2.)

Monty wakes up as there are 14 minutes left and just as Murphy and Bellamy get to him.

They help him back to the lab, where Bellamy learns that Echo has disappeared.

He finds her upstairs covering herself in white paint and her own blood.

Shes attempting to sacrifice herself, but Bellamy tells her they need her to survive.

Raven walks into the room and doesnt have time for anyones dramatics: Whatever this is, finish it.

Theyre all prepping their suits and oxygen tanks while keenly aware that Clarke hasnt returned.

Raven says theyll wait as long as they can, but the countdown clock isnt stopping.

At the satellite, Clarke isnt able to get the satellite to operate from the ground.

My fight is over, she says as she begins her ascent.

They blast off, and Clarke sees the ship as she climbs to the top of the tower.

The group makes it into zero-g, which Raven couldnt be more pleased about.

Bellamy helps her prep, and Echo lookssoconfused by everything thats happening.

Back on the ground, Clarke finally makes it to the top of the tower.

She attempts to plug in her tablet there, but the dish still wont align.

She has to physically go to the dish and move it.

She hoists herself up there, forces it skyward, and sees that the satellite is sending a signal.

Then the whole unit goes black and she throws the tablet into the oncoming death wave.

Up in space, they have about 10 minutes of air left and theres no power on the ring.

Bellamy is kicking himself for leaving Clarke behind when they are all going to die in space anyway.

And just then Monty sees the ring light up.

She did it, Raven says as she docks the ship.

By the time she gets to Beccas lab, her face is covered in radiation lesions.

And then the power goes out.

Monty is talking Bellamy through the steps of connecting it while everyone else passes around oxygen tanks.

They all end up passing out, but Bellamy connected it in the knick of time.

They wake up to an ark full of air and an Earth below full of fire.

Six years and seven days later, Clarke wakes up!

With short hair!!

And her red streaks back!!!

She has the rover and is setting up a little satellite and sending out a signal to Bellamy.

Despite that, the bunker has gone silent, she tells the sky through a walkie.

We tried digging them out for a while, but there is too much rubble.

But then she sees them.

And she goes to the rover to wake up a girl she refers to as Madi.

She tells her little nightblood that her friends are coming down.

Madi realizes something is off before Clarke does: I thought you said the ship was small?

Through a riflescope, Clarke sees that this isnt the Vesta IV.

What the hell is the Eligius Corporation?

Are they holding our Sky Friends prisoner?

Was Clarke ever in communication with the bunker or the space people?

Where did she find Madi?

How did they survive these past six years?

And why is only Clarkes area of the world green?

This episode leaves us with hundreds of questions.

I was able to get a few teases about season 5 out of Jason Rothenberg.
