Breaking Bad, Season 4

[Jesse is pointing a gun at Walter, accusing him of poisoning his girlfriend's son, Brock]

Walter:
Jesse, why? Why, in God's name, would I poison a child?

Jesse:
To get back at me! Because I'm helping Gus and this is your way of ripping my heart out before you're dead and gone! Just admit it! Admit what you did! ADMIT IT!

Walter:
I DID NOT DO THIS!

Jesse:
SHUT UP! [Jesse pushes Walter down] STOP LYING!

Walter:
I'm not, I'm not lying, Jesse, listen to me, listen to me, what would I have to gain, what possible...possible...who...who would...Oh my God... [Walter begins laughing]

Jesse:
Hey. Stop laughing. STOP LAUGHING!

Walter:
I have been waiting...I've been waiting all day, waiting for Gus to send one of his men to kill me, and it's you. Who do you know who's OK with using children, Jesse, who do you know? Who's allowed children to be murdered, hm? Gus! He has been ten steps ahead of me at every turn and now the one thing that he needed to finally get rid of me is your consent, and boy he's got that down, he's got it. And not only does he have that, but he manipulated you into pulling the trigger for him.

Jesse:
But only you and I knew about the ricin!

Walter:
No! You don't even believe that. Gus' cameras everywhere, please. Listen to yourself. No, he's known everything all along. Where were you today? In the lab? And you don't think it's possible that Tyrus lifted the cigarette out of your locker? C'mon! Don't you see? You are the last piece of the puzzle. You are everything that he's wanted. You're his cook now. You're the cook and you have proven you can run a lab without me, and now that cook has reason to kill me. Think about it! It's brilliant! So go ahead, if you think that I am capable of doing this, then go... [Walter grabs Jesse's wrist and puts the gun on his own forehead] ...put a bullet in my head and kill me right now.

Jesse:
I'll do it.

Walter:
DO IT! Do it.

Jesse:
I'll do it!

Walter:
Do it. Do it.

[Jesse does not pull the trigger. He turns to leave]

Walter:
Where are you going?

Jesse:
I'm gonna find the son of a bitch and I'm gonna kill him.

Walter:
No, don't, he'll see you coming. You'll die before you get anywhere near him.

Jesse:
I don't care.

Walter:
Jesse, Jesse, just get in your car, just go, just drive.

Jesse:
No. I'm going to do this one way or another, Mr. White.

Walter:
Then let me help.
