Torchwood, Series 4: Miracle Day

Esther:
So as soon as the Miracle happened, you sent the Torchwood email.

The Cousin:
His blood endangers the plan. We had to draw him out into the open.

Jack:
Well, you failed. I got to Shanghai. I've got the only mortal blood on the planet. If it gets into The Blessing, life switches back. I can make the whole world mortal.

[As Jack is about to slit his wrist, the Mother laughs]

The Mother:
No.

The Cousin:
Oh, no.

The Mother:
Sadly not.

The Cousin:
He's not listening.

The Mother:
He doesn't seem to get it.

The Cousin:
No, no, no.

The Mother:
Polar dynamics, Jack.

The Cousin:
Everything on this axis operates in a polar dynamic field.

The Mother:
You could reset the Blessing, your blood could make the whole world mortal again, but only by introducing it to both cities at once.

The Cousin:
Blood in Buenos Aires.

The Mother:
Blood in Shanghai.

The Cousin:
Entering The Blessing simultaneously.

The Mother:
That's how we fed it.

The Cousin:
That's how we made the world immortal.

The Mother:
And for you, I'm sorry, it's impossible.

The Cousin:
You did very well, almost worked it out, but all that spare blood of yours went up in flames.

The Mother:
So I'm just gonna have to kill you. [gives an order to her Chinese henchmen]

Jack:
Whoa, whoa, whoa, whoa! Whoa, whoa.

The Mother:
Jack, I know how your mind works. Even now you're ferociously calculating how you can get your blood to the other side of the world. But I can't allow that. Absolutely not.

Oswald:
Oh, oh, oh, oh, oh, oh, oh, oh. I'm warning you, I'll do it.

The Mother:
Then I'll die. And that's a shame, because you can blast his blood into that wall and it won't make any difference at all.

[The henchmen cock their weapons]
