At this point I can say I have some sympathy for Walt, but that is not the same at all as being on "Team Walt". At this point if you're on Team Walt what exactly are you rooting for? Previously you could say you were rooting for Walt to "get away with it", but now? The jig is up. He's lost everything. There is no more getting away with it.
We're all in the same boat now in not knowing what Walt's ultimate goal is going to be here. Sure, it's probable that revenge is going to factor into it...but I have a feeling Walt is going to be somewhat of a changed character in the final 2 since the status quo has been rocked hardcore. Therefore I call BS on anyone who'll undoubtedly say stuff like "I've been Team Walt all along!1".
In all seriousness though, I think the whole "Team Walt" thing is really dumb. As someone who has grown to hate Walt over the past few seasons, I found it especially striking and powerful tonight to feel a smidgen of sympathy for him again. In other words, just go along for the ride and witness the transformation of Walter White.
