Breaking Bad: Seven Thirty-Seven

 "I'd say these two know their chemistry..."

This is exactly how to open a second series. It carries on smoothly from the end of the previous series... but it's already clear that Walt's ambitions are going to have to reach another level. He's having to get deeper in.

Not that he realises this at the start. After a short reprise we have further scenes of terrifying violence from Tujo, and it's already clear that, through sheer necessity, Walt is going to have to get rid of him. Life is simply too dangerous and fearful with Tujo around. Raymond Cruz does a superb job of portraying an absolute and unpredictable psychopath. And yet Walt- trying to hide his fear behind calm reason- tries to persuade humself, working things out in his head, that he needs to make $737,000 from all this, and then he can stop. Hah.

It soon becomes clear that Tuho is after them, as they've seen too much. It's a case of kill or be killed, and it's fascinating that, already, Walt is not even talking to Jesse about the morality of it all: it's all about the how. And Jesse feel huge relief when Walt tells him that he has a plan- even if it involves an adaptation of the famous killing of Georgi Markov- which again subtly shows how he looks up to his old teacher.

And yet the tension builds and builds up to the shocking conclusion. Worse, Walt's problems continue to build unsustainably. He just isn't going to be able o keep making excuses to Skyler. He needs to confide in her, but can't. And his instinctive post-crime sex goes horribly wrong this time. He just can't keep living these two lives. Something just has to give- and Hank, too, is again getting dangerously close, even if he has his own problems with his wife's acknowledged shoplifting.

This is a powerful and promising opening.
