Lydia: "Is it done? Is he gone?"
Walter: "Yeah, It's done. He's gone. They're all gone."
Lydia: "Todd? Who is this?"
Walter: "It's Walt. How are you feeling? Kind of under the weather, like you've got the flu? That would be the ricin I gave you, I slipped it into that Stevia crap you're always putting in your tea."
Lydia: "Oh my God!"
Walter: "Well, Goodbye Lydia."
