Listen, I am a sucker for backdoor pilots.

I think aboutAssignment: EarthfromStar Trek: The Original Serieson a near-weekly basis.

But a backdoor pilot in a final season?

The 100

Thats a hard pill to swallow.

And this gives us even less.

Could I have used more Clarke?

Am I already obsessed with these new characters?

Anaconda starts without a cold open which is the first time this series has done that I believe?

(Still dont believe it.)

Miller falters as he tells Niylah and Jordan to keep an eye on the Disciples.

Raven starts to cry, but Clarke is resolved: We do this for him.

We do this for our family.

The doors open and Anders is there with The Shepherd.

Im coming in alone, unarmed, he tells Clarke.

She lets his people leave, so hes in the room alone with her tiny army plus Gabriel.

And thats when she recognizes that this is Bill Cadogan, the founder of the Second Dawn.

How the hell are you here?

Thats a long story.

He knows what theyre saying because Trigedasleng is the language his daughter, Calliope, created as a child.

Bill quickly surmises that if Trigedasleng survived, his daughter must have too.

Is my daughter in the key?

Here, we meet Callie Cadogan and her best friend, Lucy.

She heads downstairs to talk with him on the holographic phone.

Reese, Callies brother, is the first one on the call.

Hes on Team Dad (cult leader), and Callies on Team Mom (doctor).

Bill immediately calls for Gemma to join the call and tells her, Anaconda.

This is apparently code for the missiles are coming.

A code word every normal family has, right?

Before Callie can comprehend this,Lucy comes downstairs and Gemma hits her with a tranquilizer.

Nice knowing ya, Lucy!

Reese is already there leading people down.

They tranq him and terminate the hatch.

Nice knowing ya, Rest of Earth!

The Cadogan family finds Bill in his office working on the Anomaly Stone.

Gabriel was right, there was one on Earth!

Callie hears this and decides that means there is space for more.

She goes to the exit where she finds August, who has already knocked out a guard named Tristan.

And thats when Reese comes to help…. err, not.

Hes not the brother; hes the bad guy.

Fast-forward two years, where Callie, her brother, and others are scavenging above ground.

Theyre about to head back in when they see a small jump ship fall from the sky.

Im here to help, she yells out.

They bring her into the bunker, out of sight of everyone.

Before they are able to get to Bills office, Tristan falls to the ground and starts convulsing.

He was exposed to radiation.

Reese runs for medical help, and Becca gets to work: She injects him with her anti-radiation serum.

Callie is in awe, but she tells Becca not to mention her miracle goo to anyone.

As they draw closer to Bills office, Becca starts hearing a sound and getting a nose bleed.

Callie points out living in a bunker isn’t working.

Twenty people died by suicide in the past month and double that tried.

Bill still says no.

Callie doesnt have her family on her side.

But she has Becca and she believes in her.

(This all sounding familiar?)

She thought that meant they were damaged, but it must be intentional.

And then everything lights up as the stone turns into a bright ball.

Becca touches it and gets sucked in.

Bill walks in just as Becca is spit back.

Shes shivering and says, Were not ready.

What she saw in the stone is Judgment Day and she wont tell Bill anything about it.

Not particularly fond of not getting his way, Bill throws Becca into the box.

I will save us, not her, he growls.

So, Callie sneaks out with Beccas case.

The bad news is Reese has read Beccas notebook and knows about the Flame.

Sadly, theres no time to find a key for the handcuffs to get Becca out.

In the right mind, it can save the world, she says.

But in the wrong mind (a.k.a.

Sheidheda), it can be disastrous.

She says she wont, so they burn her at the stake.

Their mom is stuck in the middle.

I assume this means wrestling, but before we can find out, Callie shoots Reese in the shoulder.

She tells the other guards if they dont move aside, theyre next.

Callie grabs the Flame from her brothers hand and then injects him with Night Blood.

Shes about to inject her mother, but Gemma doesnt want it: Ive been to Earth.

Id rather see whats behind Door #2.

Bills guards are infiltrating the room as Callie makes a break for the door.

She makes it just in time with Gemma helping them seal the door from the outside.

When Reese awakes, Callie is gone with everyone else and hes furious and so is Bill.

Gemma tells him they just have to let Callie go.

Then he tells Reese to find the Flame by all means possible.

(Im sensing a brother-sister feud will be a main theme if the prequel gets picked up.)

As for Bill, he and the rest of his people decide to head through the Anomaly.

Where he goes is unknown for now, but we know at some point he ends up on Bardo.

Back in the present, Bill asks Clarke if Callie is in the key.

Yes, Calliope is in here but thats not how it works, she says.

She wont do anything until she sees her friends.

In walks Octavia, Diyoza, and Echo, who are now fully suited in Golden Mask gear.

How long have they been soldiers?

With timelines the way theyve been, it could have been a long time, right?

Could they possibly be loyal to the Shepherd and his war?

What IS his war?

What is Judgment Day?

Where did the Anomaly Stone from the bunker go?

And IS BELLAMY REALLY DEAD?

Lots of questions coming out of tonights episode and only eight more episodes to answer them in.

Fingers crossed this isnt aLostfinale situation because Im gonna need some answers.
