I don't understand the cigarette...
I thought we all knew Walt took it back in Season 4 or 5. He took it to set up Gus. Walt used a house plant to poision Jesse's girlfriends child... to convince Jesse that Gus did it in order to convince Jesse to kill Walt. After Gus is killed, the doctors tell Jesse that it wasn't Ricin... and the season ends with the cigarette still missing. Then in season 5 (or whatever) they search Jesses house for the ricin. Walt has it but Jesse doesn't know that... so during the search Walt plants it in the robot vacuum and pretends to find it. Where he then pretends to flush it... but he kept it and hid it in the light socket instead.
So... didn't Jesse already lose the Ricin cigarette way back in season 4? And didn't Jesse already come to the conclusion that it was later found in his vacuum? So why is he upset it's missing... again?
Also... I hope Walt becomes a meth kingpin. I hope the series ends with Walt forever becoming Heisenberg, and Heisenberg is the fucking man. The new drug Kingpin of the meth industry.
