Damn. I thought things were intense before that episode.
I was hooked right from the opening. They always manage to amaze with with their flashbacks / flashforwards.
I too cannot decide whether I think future Walt is on a revenge mission or a rescue mission.
At first it seemed like he planned to take Holly with him, I'm glad he didn't. Running off with her certainly got their attention, but we know he has unfinished business. at least in his own mind.
