Torchwood, Series 4: Miracle Day

Esther:
Torchwood, that wasn't a virus. It's gotta be some sort of malware.

Noah:
It's like nothing I've ever seen. The word "Torchwood" has vanished. It's been eradicated. If you search for "Torchwood," you get no results. Nothing gets no results.

Esther:
There's gotta be something on paper.

Noah:
Shelves are buried. It's all gone. I asked Yvonne. She said it was classified under the 456 regulations. She said you want to stay away.

Esther:
Why?

Noah:
They all died. So the story goes, anyone that worked for Torchwood was killed in action. And they died young.
