The end credits spell the warden's last name as Hutchins. However, his name tag says Hutchens.
Trivia: The pattern of the answers Caleb gave on the recent national test spells out "Waste Of Time".
Finch: Which means that contained within this string of decimals is every single other number. Your birth date, combination to your locker, your Social Security number. It's all in there somewhere. and if you convert these decimals into letters, you would have every word that ever existed in every possible combination. The first syllable you spoke as a baby, the name of your latest crush. Your entire life story from beginning to end. Everything we ever say or do... all of the world's infinite possibilities rest within this one simple circle. Now, what you do with that information... what it's good for... well, that would be up to you.
Fusco: (to Finch) Hey, I'm checking on the boy genius. Not you, the other one.
Finch: I hope you have your service weapon with you, Detective.
Fusco: Yeah, I got you a machine gun too.
Finch: May I remind you that of the many things I'm equipped to do, pursuit would not be chief among them.
Finch: Your mistakes, like mine, are part of who you are now. You can't move on from that. Believe me. I've made a sizable number. But... sometimes your mistakes can surprise you. My biggest mistake, for instance... brought me here. At exactly this moment when you might need some help.
Caleb: Yeah? Then what's the use. We're just gonna keep breaking things... over and over. Why not save everyone the grief?
Finch: The thing about the world is that it doesn't have any extra pieces. It's like pi. It contains everything. ou remove a single piece... no circle. Your recklessness, your mistakes, are the reason why, when they say, "You can't change the world," you won't listen. The world is better off with both of us in it, Caleb, rather than the alternative.
