Someone has the right idea.

There are times it does feel like it. I was here for the black-out... a period of time in which we lost everything that we weren't wearing. Trapped in the dark and the increasingly cold ship for a week.

Fear took hold, and one inmate promised to dispense food in secret, without withholding it- He was cooking people.

Test or no test, we can't let fear get the better of us and rationality flitter off to the wind.
