The train from Chicago to New York races down the railway tunnel towards Grand Central Station.

One passenger, holding in the baggage car, is determined to get off before that.

She is a mutant, and she is terrified for her life.

While the train is still in motion, she folds herself as flat as a piece of paper and slips out of the sealed door.

I made it. I made it.

She slowly gets to her feet and staggers towards the tunnels she used to call home. I've been away for too long. I thought I'd never see these old tunnels again.

I hope the others hadn't still mad at me for leaving.

But no, surely Callisto will be glad to see me again.

She understood why I left, why Richard and I...

Oh, God, Richard...

She pauses in her tracks as the memories come back.

They killed him.

Had him with a spear or something.

He begged me to give him his gun.

Said we'd only be safe together, but I couldn't.

So I left him there.

I left him behind. And then there was a gunshot. He, they... Oh, Richard, I'm so sorry.

She cries for some time, feeling everything she has ignored since she fled from her attackers.

Eventually, she forces herself to focus.

Almost there. Almost in the tunnels. I can cry about it when I'm safe. It took so long to get

here. I changed trains so many times so these monsters couldn't follow me.

I'm almost there.
