Breaking Bad, Season 2

[Walter and Jesse are stranded without water in their RV in the middle of the desert]

Walter:
I have this coming.

Jesse:
What?

Walter:
I have it coming. I deserve this.

Jesse:
Snap out of it. Alright, first off, everything you did, you did for your family. Right?

Walter:
All I ever managed to do was worry and disappoint them. And lie. Oh God, the lies...I can't even...can't even keep them straight in my head anymore...

Jesse:
You know what? Screw this. I'm walking. You can come or not. Where's my other shoe?

Walter:
Jesse...Jesse...Your body is running dangerously low on electrolytes. Sodium, potassium, calcium...and when they're gone, your brain ceases to communicate with the muscles. Your lungs stop breathing. Your heart stops pumping. You go marching out there, and within an hour, you will be dead.

Jesse:
You need to cut out all your loser crybaby crap right now and think of something scientific!
