The Fanstastic Ms. Fox

 "You have likely noticed that a great many things in your world are inefficient and unjust. At times you may find it implausible that this status quo can hold when there is so obviously a better way to do one thing, and a kinder way to do another, and so on, and that all these ways sync up, snap together and should just plain work. It seems obvious, yes?"

"Do not be alarmed. Well, actually, you can and perhaps should be alarmed, but please also understand that memory turbulence is a perfectly normal side-effect of trans-temporal projection. It's for the best. If you could consciously remember the future you're from, you'd be stuck quivering from culture shock and moral outrage. And that won't do. We spent a lot of time and energy - and you sacrificed a lot - to put you this far in the past on what we all admit is a kind of long-shot plan to make sure that things turn out right. Now go find the other people in your cell, whether they're from the same future or something close enough. (The future is inherently wobbly) Make friends, remember what you can as a collective, and take the necessary steps. Your task will be difficult, but the results are awesome. Hope is a thing we build here and now."

"Now get cracking."
