Torchwood, Series 4: Miracle Day

Gwen:
So listen, Category One is bad, yes?

Vera:
Yeah. That's people with no brain function or anyone who would normally have died. They're now officially Category One.

Jack:
Ordinary people are Category Three.

Vera:
Right. That's people with no injuries, nothing. They're fine. Then Category Two is everyone in-between. People who are alive and functioning with an illness or injury that's gonna persist, but not kill.

Rex:
Like me.

Vera:
Yes, like you.

Rex:
Wait a minute. When I got hurt, I should have died. I was Category One. But now I'm healing, so I'm Category Two. So which one am I?

Vera:
Well, that's the point. People don't fit categories.

Jack:
Worse than that, this process has given the United Nations a definition for life which is therefore a definition of death. The government now has the power to decide whether you're dead or alive. No one should have that much control.
