Also, from Talking Bad (the "talk" show that airs after every new episode) after the finale:
Hardwick (the host) asks about Walt inexplicably leaving his watch at the gas station’s phone booth. Gilligan confesses that there’s the two reasons: a cool, artsy-fartsy reason that he and the writing team made up and a real reason. The real reason is due to continuity, since Walt did not have the watch on at Denny’s during the first season 5 flash-forward. The artsy-fartsy reason is that Walt didn’t need the watch anymore as he was about to encounter Jesse, who gave him the watch, for the last time.
Also, loved the ending. I was able to stay two steps ahead of the writers for the finale, but it didn't make the episode any less satisfying. Correctly guessed beforehand that the ricin will be for Lydia, the M60 was for the Nazis, and that Walt will eventually "rescue" Jesse. The wild card for me was what Walt was planning with Gretchen and Elliott, but by the first commercial break, I figured out Walt's plan (although the appearance of Badger and Skinny Pete was a welcome surprise).
Overall, I thought the finale was very well executed.
One of my favourite lines of the night: "I don't really know how to feel about this, morality-wise!"
