Alan Sepinwall parses the title for us:

As pointed out on the Internet earlier in the week, the title can be read as the chemical symbols for iron, lithium and sodium (aka "blood, meth and tears") or as an anagram for "finale." It could also be referring to the Marty Robbins' song "El Paso," which plays in the tape deck of the stolen New Hampshire car, and which features a Mexican girl by the name.

Iron Lithium Sodium! Blood Meth and Tears!

I always liked that song (there's a West Texas highway off ramp that always makes me hum when I pass it) but I had forgotten the girl's name in it.

I lean towards Jessica. Apart from admitting he was doing it for himself, it reminded me of Ten's regeneration, and Heisenberg was a monster who didn't deserve that (although not the monster GRRM thought him--jesus, what a misreading of the text...).

Ooh, I'm curious. Link please?

I pretty much disagree with any reading of the text that buys into the bullshit narrative that Walt used to be a good guy before he got cancer. He was a selfish vindictive prat in the series premiere, so I'm not sure why I'm supposed to believe he was ever anything else.

"Walter White is a bigger monster than anyone in Westeros"--yes, Walt routinely kills hookers just to watch them die. Good Lord.

I agree with you 100% that he was never a hero (I got a workout in IO9's "hero gone bad" thread, and I dislike the term anti-hero because of how the internet uses it.), that the relationship with Jesse was negative and abusive and vicious as soon as we saw it, not something that turned sour, that he was in this for himself, etc, but does GRRM not read what he writes?

HAHAHAHAHA, how did I miss that a couple weeks ago? Dude Walter White is not even the worst person in Breaking Bad (HELLO NAZIS).

Apart from admitting he was doing it for himself, it reminded me of Ten's regeneration

Me too!

The finale wasn't what I expected, but I found it very satisfying. Heisenberg was a monster, but I always felt for Walter White the person, so I liked seeing a bit of both of them.

In retrospect, "Ozymandias" was the climax of the series. The life of Heisenberg killed Hank, Mr. Doing It All for His Family ended up getting family killed, and the last two episodes are Walt trying to make up for it as best he can. He can't fix everything, but he can try to get things in order.

Also, Jesse lives, thank God. And to my surprise, even though I've been pulling for a Jesse-kills-Walt ending, when it came to that point, I didn't want it anymore, and I loved that Jesse didn't do it because it would just be doing what Walt wanted, yet again, and he was done with that.

'Breaking Bad': Creator Vince Gilligan explains series finale:

There was a version we kicked around where Walt is the only one who survives, and he’s standing among the wreckage and his whole family is destroyed. That would be a very powerful ending but very much a kick-in-the-teeth kind of ending for the viewers.

I guess our gut told us that it would feel satisfying for Walt to at least begin to make amends for his life and for all the sadness and misery wrought upon his family and his friends. Walt is never going to redeem himself. He’s just too far down the road to damnation. But at least he takes a few steps along that path. And I think more importantly for him than that is the fact that he accomplishes what he set out to accomplish way back in the first episode: He leaves his family just a ton of money.

That is AWESOME. I am definitely choosing to believe this version.
