Toshiko Sato:
[as Captain Jack takes an alien artifact out of a box] You said we weren't allowed to use that again.

Captain Jack Harkness:
It's just a mind probe.

Ianto Jones:
Remember what happened the last time you used it?

Captain Jack Harkness:
That was different. That species has extremely high blood pressure.

Ianto Jones:

Gwen Cooper:
Jack, we can't do this. What if you're wrong? If she is human, it'll kill her.

Captain Jack Harkness:
I'm not wrong. We have to find out what she is.

Toshiko Sato:
Take it easy, Jack. Stop at the first sign of trouble.

Ianto Jones:
Or the first sign of exploding.
