I'm all for Walt Scarfacing Todd's uncle's group. But I hope it's not to rescue someone, but more along the lines that they disgraced Heisenberg and took away his empire. I want to see Walt go out a megalomaniac, not a redemptive character.
I'd like to see him redeem himself, but I'm not opposed to the other outcome. Either way, I think it's safe to say there will be some Scarfacing going on.
