Ridiculously intense episode. You have to love the psychology of arguing about killing Lydia right in front of her.
But the train robbery scene - holy shit. This show has trained its viewers to expect things to go wrong, which creates even more suspense in situations like that. Everything goes off without a hitch (for the most part) and then BAM... literally.
Love the continued cameos by Bill Burr.
Also Walt's "breakdown" in Hank's office was some legit Heisenberg shit. I said it in one of my earlier posts, but if Hank survives to the end of this series, his career is toast.
Skylar finally gets her leverage over Walt. Should be interesting to see that relationship evolve now that the kids are out of the way. Seems like it makes it that much more likely that Walt will be responsible for her death, either directly or indirectly.
