Love to see that I started this thread. Cant wait for Sunday. Re-watching the first half of this season with my roommate as he catches up. Love that the question isn't if Walt dies, but how he dies
That and the machine gun. Perhaps I was wrong about Walt being cancer free in the flash forward. However the flash forward was a year and Walt told Hank he wouldn't have anyone to prosecute in 6 months.
If I remember correctly, the ricin behind the outlet was the ricin that was originally made to poison Gus. Jesse never used it, and Walt stole it in his scheme to frame Gus for poisoning Jesse's gf's son.
