Star Trek: Discovery

Previously on Star Trek: Discovery...

Any rational explanation

for the seven signals continues to escape me.

Tell us what the signals mean.

I know nothing about them.

You want to help, delete the Sphere archive.

As long as there's any possibility

of Control gaining access to the Sphere data,

everything will die.

The archive will not allow itself to be destroyed.

Instead of fighting time, we go with it.

You can transfer the Sphere archive into the suit

and let the wormhole take it forever.

Look, just come home.

That version of me is dead.

And I'm not going back.

You're Control. You won't win.

Struggle is pointless.

Our mission parameters have changed.

He's taken the Sphere data!

No!

Captain, we cannot stop the data transfer.

The transfer speed is increasing.

We haven't come this far to lose everything now.

You have to let me go, Michael.

If we do that, you'll get yanked back.

At least this way she would have a chance.

I'll find you, Mom.

Now, with no suit,

no time crystal...

It'll always be one step ahead of us.

Dr. Burnham was incorrect.

What we do now has the power to determine the future.

The board is yours, Michael.

When the timestorm passes,

I'll come back for you, baby girl.

For you and your father.

I promise.

Incoming transmission

from Amanda Grayson.

Michael, I heard what happened.

I am so sorry.

How did you hear?

Spock.

All this time... I thought she was dead.

But it was so much worse.

She was trying to stop Control.

And I stopped her.

I failed her.

Then I lost her...

- all over again. - Michael,

you have it backwards.

You found her.

You will find her again.

That is who you are.

Mother. I apologize for the interruption,

but the captain needs us.

Take care of each other.

I love you both.

Thank you.

Another signal has appeared.

This new signal is the fourth of seven.

It appeared over the Klingon planet of Boreth.

The time crystal in Dr. Burnham's suit was destroyed.

There's no way she could have come back

- to create that signal. - And she said she had

no knowledge of them.

Which would suggest these signals were created by

another time-travelling entity.

Maybe a trap?

An agent of Control from the future?

None of the events linked to the signals would indicate that.

That fact that one of them led us to save

the people of Terralysium, whose ancestors were saved

by Dr. Burnham herself, makes me think that

- these signals are... - Speculating about

what the signals could mean

or who created them is unproductive.

What are you suggesting, Commander?

I am asserting that waiting around for these signals

to provide us answers has proven to be

a colossal waste of time.

To say nothing of the fact that Leland is the A.I.

He is Control.

We should be joining Agent Georgiou

in her search for him.

We have determined

that the Sphere archive could not be

removed nor deleted from this ship.

By using Discovery

to pursue Captain Leland, we would be placing

the data directly within his reach.

We all want to stop him.

I understand why you want to lead the charge,

but our priority is safeguarding that data.

So, we focus on the mission at hand:

this new signal, and why it appeared over Boreth.

Mr. Tyler, any insight?

To the Klingons, Boreth is revered for one reason.

The monastery dedicated to Kahless.

It's the only non-native structure on the whole planet.

I don't know how it relates to the signals,

but I can reach out to Chancellor L'Rell

to arrange passage there.

Excellent. Do it.

*STAR TREK: DISCOVERY* Season 02 Episode 12

Episode Title: "Through the Valley of Shadows"

Door.

Michael.

I saw you back there.

Whatever it is you're not telling us about Boreth...

I need to know.

Boreth... is home to my son.

Your son?

Technically, Voq and L'Rell's son.

L'Rell had hidden him away for his own safety,

and I wanted to raise him...

...to protect him.

And instead, I risked both of their lives.

He was placed in the care of the monks on Boreth,

where he'll be raised as a son of none.

Like I was.

Ash, I had no idea.

I'm sorry.

I couldn't tell anyone.

I only wish you'd told me

so you wouldn't have to carry it alone.

Well,

that's something we both struggle with, isn't it?

What is it?

A Section 31 ship just missed its check-in.

It might be nothing.

When it comes to Leland and the A.I.,

no inconsistency is too small.

You want to go after him,

for what he did to your mother.

- Are you gonna try... - To stop you?

I don't think that's possible.

Agent Tyler,

the D7 has arrived with Chancellor L'Rell.

You should go.

Be careful, Michael.

Please.

The monastery is considered

the most sacred site in the Klingon Empire.

Their contact with outsiders has been almost nonexistent

since our world was young.

Control is a significant threat to all of us, Chancellor.

Something in that monastery might even the odds.

Is there any reason you can think of

that the signal would lead us there,

The monastery on Boreth was not only built

to house the Followers of Kahless,

but to protect a rare mineral native to the planet,

guarded with Klingon lives for generations.

Time crystals.

Dr. Burnham's suit was powered by a modified time crystal.

A new time crystal could let us send the Sphere data

into the future after all.

The power to manipulate time

is a weapon unlike any other,

and the very reason we no longer exploit the crystals.

But in this case, our mutual survival

depends upon time manipulation to defeat Control.

Maybe the final three signals will show us how to do that.

Send me down to Boreth.

No!

We will not have this conversation

in the presence of Captain Pike.

Chancellor, circumstances are dire,

and time is critical now. I offer you my full discretion.

For Agent Tyler to go to Boreth would endanger a life.

- L'Rell! - The life of our son.

His existence and yours must be kept secret.

I would never put the Empire at risk.

I have the right to see him.

The dead have no rights.

If it were discovered that our child or you were still alive,

the Klingon Empire would be vulnerable to sedition.

I forbid you to go.

I'll go. I agree

with Chancellor L'Rell. It isn't safe for either of you to go.

Nor would it be safe for you, Captain.

Boreth is not for the faint of heart.

Even as chancellor, I hold no sway

over the monks who guard the crystals.

Noted. Can you help us establish communications with them?

I can arrange an audience.

But no Klingon, let alone a human,

has ever taken a time crystal from the monastery

without great sacrifice.

The alternative is worse.

Let us proceed.

According to Tyler, every Section 31 ship

is required to check in on an hourly basis.

But this ship checked in ten minutes past its hour.

Because of the clandestine nature of their mission,

they're not required to provide any further information

on their status.

You want to investigate in person?
