(S02E10) As I watched this episode, I was pondering, can you put the toothpaste back in the tube? What about taking a bite from the apple from the tree of knowledge, if you want to get Old Testament about it? Walter White has issues with what he's done, how he's rationalized his doing them and now, seemingly, wants a fresh start. But as another saying goes, be careful what you wish for.

For viewers who haven't yet watched the episode, from here on I'm talking spoilers, so be forewarned.
