The latest episode of Breaking Bad opens with DEA agents arriving at the White residence. They're there to escort the family to Hank and Marie's home for their protection. Walt, however, insists that he stay behind because he believes he is the real target and that no-one will be safe if he's around.
Walt confides in Skyler that he's made choices since he was diagnosed with cancer, and he alone should be suffering the consequences. "And those consequences are coming," he continues. "No more prolonging the inevitable." Skyler, Walt Jr and baby Holly all leave for the Schrader house.
While Walt sits by himself with a revolver, Walt Jr and Marie are less than happy about his decision not to come.
Hank tells them not to worry, that the whole threat is just a "smokescreen". He theorises to Gomez (awesome!) that this may be related to his investigation into Gus Frings. The man lays it straight - he believes Los Pollos Hermanos is a front for "the biggest meth distributor in the south west", and he wants Gomez to go to the laundry and look around.
Gomez and his partner investigate the laundry, the former taking photographs of the place, but they don't find the secret entrance into the superlab. Downstairs, Jesse and Tyrus keep quiet before Gus tries once more to convince Jesse to give him the go-ahead to kill Walt.
Jesse reiterates that if something "final" happens to Walt, there will be a problem: "So what are you going to do?" Gus: "There will be an appropriate response."
After his day's work, Jesse checks his voicemail to find a number of urgent-sounding messages from Saul. At Saul's office, the lawyer stuffs Jesse's money in a bag and gives it to him. Saul plans to bolt until things calm down, telling Jesse about Gus threatening to kill Walt's entire family. Before Jesse leaves, Saul pleads with him to put a good word in with Gus.
Hank, meanwhile, is looking at the photographs Gomez took. The laundry looks clean. Skyler looks on and tries to ring Walt but to no avail.
Jesse is lying around at his home when he receives an urgent call. He rushes to the hospital to find an extremely upset Andrea - Brock has all of a sudden come down with some sort of flu, but he keeps getting worse. Brock is being treated in the ICU.
Jesse does his best to comfort Andrea. When Andrea is allowed to see Brock, Jesse goes out to have a cigarette, but panics big time when he realises the poison - the ricin he hid inside his 'lucky' cigarette - is missing. It quickly hits home that Brock has been poisoned.
Mr Pinkman rushes back inside and begs Andrea to tell the doctors about ricin. He then promptly leaves, telling her he's got to see someone.
That person is Walt, who has barricaded himself in with his gun. He lets Jesse in, but Jesse grabs the gun with Walt's guard down and points it at him. Jesse demands to know why Walt poisoned Brock - only the pair of them knew about the ricin.
Walt insists he had no hand in it, saying he had no opportunity to nor the motive. Jesse counters that he must have done it to get back at him for helping Gus. Then, Walt starts to laugh manically and realises: "Who do you know who's okay with using children... who do you know who's allowed children to be murdered? Gus!"
He explains that Gus manipulated Jesse into finally consenting to Walt's death, and not only that, but he is the one who's actually going to pull the trigger. Gus has cameras everywhere - he must have known about the ricin all along - and reckons Tyrus must have lifted it from Jesse's locker.
Walt grabs Jesse's hands and puts the gun against his forehead, telling him to shoot if he truly believes Walt is capable of killing a child. Jesse stands down before starting to head out to kill Gus. Mr White stops him, though, insisting that he will die before he gets anywhere near Gus.
When Jesse refuses to back down, Walt utters: "Then let me help."
A day has passed, and Jesse is woken up at the hospital by Tyrus, who orders him to get back to work. Jesse brushes him off, saying he's not leaving and that Gus should come speak to him himself.
As Tyrus leaves, Jesse texts Walt: "Think I got his attention." Walt, meanwhile, is making a remote-detonated bomb.
Gus arrives at the hospital's parking garage and speaks to Jesse face-to-face. He tells him he's got a business to run, but Jesse can't bear to be away from Brock. When Jesse reveals his suspicions that Brock was poisoned, Gus tells Jesse he can take the rest of the week off. He puts his hands on Jesse's shoulders to comfort him, but watching the scene, it's anything but comforting. Who knows what's going on inside Gus's head?
Gus, Tyrus and a second henchman are heading back to the drug lord's car with Walt watching far away on top of another building with binoculars and a remote detonator - Walt is ready to blow up the car. As Gus draws near, he suddenly stops and grows suspicious. "Why'd you stop!" Walt mutters. Gus looks outside. It's extremely tense as Walt ducks behind cover.
As Walt peers out again, he sees Gus walk away from the car.
Breaking It Down...
• With one episode remaining in Breaking Bad's fourth season, it looks like there will be an epic showdown between Walt and Gus.
• 'End Times' wasn't as thrilling as last week's 'Crawl Space', but it continues to reinforce that Gus is cold-hearted and plain ruthless - it'd take something special for Walt and Jesse to take him down. And how great was that final scene?
• It was obvious Jesse was never going to shoot Walt, which perhaps slightly ruined some of the impact of the scene, but both Bryan Cranston and Aaron Paul were sublime and it was still a riveting confrontation.
• Jesse calls Tyrus Gus's "errand boy" - ha!
• Andrea can't get a break, can she? First, Tomas is murdered. Now, Brock looks like he'll be following his late brother.
• Gomez is back! It's been too long.
• We're dying for Hank to expose Gus as the drug lord he is! Maybe Skyler can lend a hand...?
