Gwen and Jack in “Day One”

What are we doing, having Chinese while a girl fights for her life? We should be helping her.

Actually, while we've been eating, the computers have been running a full bio-scan on Carys, profiling her blood, metabolism, organs, the works. So we can see what effect the alien is having on her. They've also been taking samples of the air in the cell, so we can analyse any change in the environment around her. Now, is that enough? Do you want more? 'Cause... gets kind of boring.

You've been hidden down here too long. Spending so much time with the alien stuff. You've lost what it means to be human.

So remind us. Tell me what it means to be human in the twenty-first century.
