Previously...
Forget the past! You're here now. And you've made everything worse!
Polaris, no!
Oh, man.
I'm working on a way
to undo what has been done.
Destroy.
Target acquired.
Halt.
Halt, halt...
Another headshot, Rover?
Destroy.
Didn't we just talk about this? We wanted its vocal modulator, remember?
That's in the head.
Destroy.
Don't worry about it.
- Marrow! - Oh, hey, Bish.
Why are you still bushwhacking Sentinels?
I told you, it's not the way to scavenge parts for Rover.
You know, maybe that headshot did us a favor.
What? Are you listening to me?
- Yes! - Good.
The chest lens isn't cracked.
That is always the first to go. Rover, twist it out of there.
Destroy.
Aren't X-Men supposed to listen to their leader?
That girl is so bullheaded.
She's putting way too much trust into that walking pile of wreckage.
Perhaps, but I can see why she's befriended him.
He listens to her.
It's a robot, Charles.
To us.
It's a little loose.
Better not lean forward too much until I can fix it.
Destroy.
Let's move it, Marrow.
Recovery Sentinels are probably on their way.
Okay, just because you've seen me ignore Bishop doesn't mean you can.
Rover!
Destroy.
You need a watch, Summers.
Not when I've got you telling me where to go, when to be there.
Believe me, I haven't begun to tell you where to go.
Charles...
You there?
Can you hear me, Charles?
Bishop, continue on ahead. I'll catch up.
All right, but be careful.
Yes, Logan. I hear you.
Scott, this is a surprise.
Has something happened?
You might say that.
Summers here had a little stroll down memory lane
and came across something pretty important.
It's, uh,
about the explosion at the institute.
I'm not sure, but...
Perhaps it's best if I just take a look myself.
Jean, what's wrong?
Jean was the cause.
No, you can't blame her. We don't know what happened.
No, we don't. Not yet.
But having seen that psychic fire before,
I now fear Jean may have a larger role in our fates than I ever realized.
You saw it before? Where?
In the memories of Magneto's daughter Lorna.
She is one of the few survivors here
who actually saw the sky that day 20 years ago.
There is little doubt it's what ravaged the world.
You're saying Jean was the cause of the apocalypse, not the war?
There is no way that she...
What happened?
You and I need to speak privately.
Okay. Go on.
I've only begun to understand the true depths of Jean's power.
However, Jean, I know very well.
And only in times of great stress does that power surface.
- What are you saying? - The war, Logan.
I firmly believe it's what pushes her to lash out.
And I also believe that by stopping it, you will stop Jean.
And if I can't?
Then she must become your focus.
Charles, what do you expect me to do?
Whatever is necessary.
- Why were we cut off? - That's the way it goes sometimes.
So now what?
Me and the X-Men are gonna figure out how to save the world.
You're gonna figure out if you're joining us.
"shout. Watch the kids run."
"The kids run and shout."
Say that, Rover. The kids run and...
Destroy.
- Destroy. - What?
Destroy. Destroy, destroy, destroy!
Lift me up.
Quick, put me down.
Time for night-night, Rover. Go, go, go!
We've got trackers at the perimeter!
Bishop, we're in lockdown. Where's Professor X?
Still on his way.
I told you to be careful.
- Where's Marrow? - With Rover. She wouldn't leave him.
- Seal the entrance. - But...
Now!
Destroy.
They're gone.
They must have followed you up here.
Knock it off, Marrow.
Ever since he showed up, Mastermold has been gunning for him.
And it's not fair to the rest of us.
Why don't you just leave us alone?
Get some distance now.
Well, and to think I wondered why her only friend is a robot.
I do understand her feelings.
This is a world none of us should have to live in.
Speaking of which, you spoke to Wolverine. Is he making any headway?
He has delayed the war.
But obviously, he has not prevented it.
Now I fear the countdown to zero hour has already begun.
If only Logan knew the exact time, the very moment the sky fills with fire,
perhaps that would help him prevent it.
I have an idea.
See it?
You mean that detention center?
It's not just any center, it's the original.
The one Mastermold used to upgrade itself.
Where it started rebuilding its Sentinels.
Interesting.
- But how does that help us? - Because last time I was inside,
I saw where Mastermold's old components were stashed,
including its data storage unit.
Of course.
It would possess a record of events dating back to...
To perhaps even its creation.
- I say we raid the place. - Agreed.
But getting in is one thing. Bringing something out is another.
- Not if we have a distraction. - It would have to be a fairly large one.
Rover large enough?
You can forget that right now, Bishop.
Sarah, please. Let us explain.
You actually want to send Rover in to fight five Sentinels?
He can handle himself. I've seen it.
Yeah, against one. It's too dangerous!
- That thing is not your pet, Marrow. - No, he isn't. He's one of us.
And his life is worth more than some crazy plan to help him.
I don't need your permission. Now go get it ready, we're leaving in 10!
Sarah...
If anything happens to him, I will hold you responsible.
I've got a line of sight through a window. I can teleport us in that way.
Good.
Marrow, is Rover in position?
- Marrow! - Yeah. We're ready.
Okay, Vanisher, let's do it.
This way.
Destroy.
- How long were you held here, Bishop? - Most of my life.
It's where I was born.
Was this yours?
I was just a kid and not much of a threat.
I didn't even get my powers until I was 14.
No, this cell belonged to a mutant the machines were afraid of.
Wolverine.
He was hunting Mastermold and got himself captured, hoping to find it here.
- Did he? - Yep.
Why do you think Mastermold needed a new body?
Of course.
Even after Mastermold went into hiding, Wolverine kept coming back.
- Why? - For me.
- He saw that my parents were gone. - He took care of you.
- For how long? - Ten years.
In that time, he taught me to be an X-Man right under the Sentinels' noses.
When I was ready, he broke me out.
This is it. Hellion.
Huh. That's new. It means we got about one minute.
Marrow, better send Rover in.
Marrow?
Marrow, answer me!
- Here it is. - It doesn't appear Marrow is coming.
Vanisher, can you teleport us?
Not without seeing our destination.
- We must move it outside, first. - Then that's what we'll do.
Mutant identified.
Halt, mutant.
Targeting.
Stay behind me.
Destroy?
No, Rover. You can't.
You won't survive it. You...
You can't.
I'll draw their fire.
Mutant identified.
Halt, mutant.
Mutant detected. Target acquired.
Retrieving and securing property.
Rover!
Halt, mutant.
Vanisher, wake up. We need you.
Targeting.
Destroy.
I have it.
Mutant detected.
Targeting.
Rover! No!
Destroy.
Rover! Get out of there!
Targeting.
Destroy.
Rover.
We must leave.
No! We can't leave him!
Rover!
Run.
I have costly news, Logan.
Through great sacrifice,
we have discovered how much time you have left before the end.
What are we looking at?
A fiery tide will overtake the Earth beginning at exactly 9:43 p.m.,
eight days from now.
Tell me it was worth it.
You know Wolverine as well as I.
Now that he's aware of the time frame, he'll make the hard choices.
Marrow was right about Rover.
He was one of us.
He gave his all...
Like an X-Man.
Thank you, Rover.
Tell Mastermold I can lead him to Charles Xavier.
