I have spent my whole life scared, frightened of things that could happen, might happen, might not happen, 50 years I spent like that. Finding myself awake at three in the morning. But you know what? Ever since my diagnosis, I sleep just fine.

Chemistry is, well technically, chemistry is the study of matter. But I prefer to see it as the study of change.

Cheer up beautiful people... this is where you get to make it right.

I have lived under the threat of death for a year now. And because of that, I have made choices. Listen to me. I alone should suffer the consequences of those choices, no one else. And those consequences, they're coming. No more prolonging the inevitable.

You clearly don't know who you're talking to, so let me clue you in. I am not in danger, Skyler. I am the danger. A guy opens his door and gets shot and you think that of me? No. I am the one who knocks!

The universe is random. It's not inevitable. It's simple chaos. It's subatomic particles in endless, aimless collision. That's what science teaches us, but what is this saying? What is it telling us, when on the very night that this man's daughter dies, it's me who's having a drink with him? How can that be random?

Skyler, you are the love of my life, I hope you know that. Walter junior, you're my big man. There are... there are going to be some things, things that you'll come to learn about me in the next few days. I just want you to know that, no matter how it may look, I only had you in my heart. Goodbye.
