I was wondering why no one had commented yet. That whole final scene had me on the edge of my chair. Kim deserves an emmy for that scene alone. She's so damn good in the show lately, which is why I've recently found myself hoping she's still alive in the Breaking Bad universe.
edit: And on another note, my wife never bothered to start this show even though she loved Breaking Bad. So we started the series from the beginning last night. I've forgotten most of it at this point, so it was interesting to see how far they've all come since that first episode (and *****, I want more Tuco!).
