With the plan to kill Gus with a car bomb failed, Walt hurriedly removes the bomb from Gus's car and rushes into the hospital to ask Jesse if there is any other way to catch Gus off guard. Before Jesse can answer, however, he is taken into custody by federal authorities to answer for how he thinks Brock was poisoned with ricin.
As detectives grill Jesse, Walt tries to find Saul, who had absconded when the situation with Gus became dicey. Saul's secretary, who is cross with Walt for breaking the office's window to gain entrance, extorts him. He then makes his way back to his home to get his money, but stops when he realizes Gus's men may have his home under surveillance. He calls his neighbor to check in on his home, telling her that his family was on vacation and he wanted to make sure he didn't leave the stove on. As he suspects, Gus's goons are watching his home. With this knowledge, he sneaks into his house to take some of his money.
Back at the police station, Saul arrives and forces the detectives to leave while he consults with Jesse. When asked about a way to get at Gus, Jesse thinks of one thing: after killing Don Eladio, dismantling the Cartel, and killing Joaquin, Gus paid a visit to a nursing home to gloat over Hector "Tio" Salamanca.
When Walt learns of this, he travels down to Casa Tranquila to talk to Hector. He tells him that even though Hector wants him dead, there is someone else that Hector loathes more than him: Gustavo Fring. Walt promises Hector that he can get his revenge against Gus if they work together.
Afterwards, Hector calls in his nurse and, using a letter board to communicate, tells her "NEED DEA". After some confusion, the nurse takes Hector to the DEA, where he insists on talking with Hank Schrader. Even though Marie, Skyler, and Junior are certain this is a trap, Hank meets with Hector. Once they are face-to-tace, though, Hector does nothing but taunt Schrader, using his aid and her letter board to tell him "SUCK MY (DICK)" and "FUC(K YOU)".
The meeting with the DEA serves its purpose, however: Tyrus has been tailing Hector and sees him leaving the DEA office.
Jesse is informed by the detectives that a tox-screen run on Brock revealed no evidence of ricin poisoning. As such, Jesse is let off the hook and is free to leave. As Jesse leaves, however, he is tased and abducted by Gus's men. Tyrus, who had come to Hector's bedroom after his return to Casa Tranquila, informs Gus of Jesse's acquisition and Hector's apparent betrayal. Tyrus offers to take care of Hector, but Gus is adamant on ending matters with Hector himself.
Gus arrives at Casa Tranquila and, after Tyrus gives him the all-clear, confronts Hector, calling him a coward and a "crippled little rata". He takes a syringe of poison from Tyrus, informs Hector that it would be his last chance to look at him, and prepares to inject him.
To Gus's surprise, however, Hector looks at him and meets his gaze. Hector's face is one of sorrow and remorse, but then turns to one of rage and hatred as he begins to tap furiously at his bell. Little did Gus and Tyrus know, before Tyrus entered Hector's room, Walt had attached his bomb to Hector's wheelchair and rigged it to detonate when he rang his bell.
Gus realizes this moments too late: the bomb goes off, killing Hector and Tyrus instantly and mortally wounding Gus, who leaves the room and straightens his tie as the nursing home staff look on in horror at the sight of half of Gus's face being blown off, exposing part of his skull, before he collapses and dies.
Walt is parked at an airport, listening to the news on the radio. When he hears of the Casa Tranquila bombing and reports of three people being killed, he departs immediately for the superlab. He kills two of Jesse's guards and frees Jesse, informing him of Gus's demise.
The two then set about to open every chemical container in the lab, flooding the floor with volatile chemicals, then rigging a frayed wire to a Christmas light timer, leaving the lab before the timer goes off, igniting the chemicals and destroying the superlab with a powerful explosion.
On the roof of the hospital, Jesse tells Walt that Brock was expected to make a full recovery: it wasn't ricin that poisoned Brock, but a plant called "Lily of the Valley ", which has poisonous berries that children may eat, thinking it edible. Nonetheless, Walt reassures Jesse that Gus had to die, and they did what they needed to do.
Walt calls Skyler, who saw the news of the Casa Tranquila bombing, and asks him what he did. Walt simply answers, "I won." Satisfied, Walt drives home.
Unbeknownst to Jesse, Walt has a particular potted plant in his backyard: a Lily of the Valley...
This episode contains examples of:
- Action Dad: Walt truly shows what he is capable of when he's driven into a corner.
- Angry Eyebrows: Hector spends two whole seasons refusing to look Gus in the eye. When he finally does, he really makes it count.
- Asshole Victim: Gus and Tyrus Kitt clearly had what was coming for them for going after Walt's family and Hank.
- Badass Boast: Walt gives a laconic one:Walt: I won.
- Batman Gambit:
- After Walter learns about Hector Salamanca and his location, he conspires with him, has him talk with the DEA, and gives him the bomb, expecting Gus to make his appearance as he uses Hector to blow himself and Gus up. Gus took the bait all too well.
- Turns out Walter pulled one off an episode earlier. He poisoned Brock with a Lily of the Valley plant in an attempt to make Jesse think Walt used ricin, and then convince him that this was Gus' plan all along.
- Can't Get Away with Nuthin': The one mistake Gus makes in the entire series by deciding to kill Hector personally is the one mistake that gets him killed.
- Camera Abuse: The camera gets coated with fluid as Jesse and Walt coat the superlab in all of the chemical fluids.
- Curse Cut Short: Hector's insulting messages to the DEA are cut off at the last word or letter both times.
- Deadpan Snarker: Tyrus' replacement: "You wanna cook with a broken arm?", and, "You got a problem with stairs!?".
- Death Glare: If looks could kill, Hector wouldn't need Walt's pipe bomb to end Gus!
- Disabled Snarker: When Hector goes to the DEA and attempts to have his nurse spell out SUCK MY DICK and FUCK YOU to Hank.
- Double-Meaning Title: Not only does this episode feature the final face off between Walter and Gus, but it ends with half of the latter's face literally blown off.
- The Ending Changes Everything: Anyone who took Walt's pleas about Gus poisoning Brock at the end of the previous episode on face value are forced to completely reevaluate the scene (and all of his interactions with Jesse afterward) with this episode's final shot.
- Enemy Mine: Hector Salamanca teams up with Walter White, who nearly killed Tuco and was the ultimate reason the Cousins got killed, to take down Gus, the man they both hate.
- Even Evil Has Loved Ones: There is a framed picture of Hector, a child, and two baby twins seen in the nursing home he is kept in. The kids are Tuco and the Salamanca twins. A flashback reveals that Salamanca believes that "family is all," which is why they're all so Ax-Crazy about avenging each other. He even keeps Eladio's necklace on the photo frame.
- Even Evil Has Standards: While Walter has become ruthless enough to poison a child, he still made sure it was non-fatal.
- Evil vs. Evil: What originally started as Black-and-Gray Morality, with Gus as the Black and Walt as the (darker) Gray, clearly turned into this at the end. Well, Walt didn't intend to kill Brock as we see later, but this proves that he's nearly there.
- Eyes Are Unbreakable: Averted: Gus's right eye is totally obliterated.
- Face Death with Dignity: Hector went out in a blaze of glory, killing the man who destroyed his family, and Gus didn't even panic even when half of his face was blown off.
- Facial Horror: Gus meets his end when hit with a bomb, but not before surviving long enough for the camera to pan around and showing half of his face blown off.
- Failed a Spot Check: Even with Tyrus standing right behind Hector, he somehow fails to notice the big bomb stuck to Hector's wheelchair. Prior to that, Tyrus had swept the room for bugs in preparation of Gus's visit and also managed to miss Walt hanging outside the window to plant the bomb afterward, despite Hector's next room neighbor almost blowing his cover by cheerfully hailing him through her own window.
- Fiery Coverup: After killing Gus, Walt goes to the superlab to free Jesse and they both proceed to spill chemicals all over the place and exit, pulling the laundry's fire alarm as they go, before the timer they set up gives off a spark, triggering a conflagration that torches the whole basement down.
- Five-Second Foreshadowing: Jesse informs Walt at the end that Brock wasn't poisoned with ricin; instead, it was with some Lily of the Valley. And then the ending shot in Walt's garden happens...
- "Last chance to look at me, Hector..."
- After Hector does look at him, he repeatedly rings his bell and the sound it gives comes off as noticeably muffled and tinny (as if something's impairing its proper working), right before the camera pans down to show the bomb wired to it.
- We see and hear the horrified reactions of the nursing staff as they approach Gus from his disfigured side before we see the disfigurement itself.
- "Did you just bring a bomb to the hospital?" Walt blows up a nursing home later.
- Turns out the teddy bear at the opening of Season 2 didn't actually foreshadow Walt's end...note
- Another one hinting at Gus' fate. When he is in the car at front of the nursing home, the camera is framed so that shadows fall on the right half of his face.
- Gilligan Cut: Hank is in protective custody at his house due to Gus making a threat on his life. Gomez tells him that Hector Salamanca is at the DEA office and wants to talk to Hank, and only Hank.Steven Gomez: If you did want to talk to this guy, there's no safer place than the office.
Skyler White: I don't think this sounds like a good idea.
Walter White, Jr.: Yeah, I agree, Uncle Hank.
Marie Schrader: It is a ridiculous idea, and there is no way you are going to do it, end of story.
[Cuts to Hank at the DEA office]
George Merkert: Hank, thanks for coming down. note
- Karmic Death: Hector's bomb destroys half of Gus' face, making him resemble a certain supervillain. The camera focuses on his uninjured side (the "legitimate" fast food mogul which everyone sees) - and slowly pans around to his disfigured side (representing the blood-soaked meth dealer). His death is also a reference to how a chicken will continue to walk around for a bit even after it's beheaded. A fitting end.
- Laser-Guided Karma: Gus used Jesse to taunt Hector as he killed his grandson in Mexico, and also successfully (for a while) drove him against Walter. He relayed the subsequent information to Walter, who finally found a way to corner and kill Gus.
- Lured into a Trap: Gus visits Hector at the nursing home to put him down after the latter went to the feds... only Hector didn't tell the feds anything (he was just trolling the feds) and the trip was made to coax Gus to get close to him and the pipe bomb Walt strapped to his wheelchair.
- Meaningful Echo: Jesse's "Did you bring a bomb to a hospital?!" is very reminiscent of Walt saying to Jesse, "You brought a meth lab to the airport?!" in "4 Days Out". Interestingly, the roles are reversed in this case.
- 'Look at me, Hector'... Gus uses it as a taunt to the old helpless Hector who just lost his friends and family... And when Hector finally looks at Gus, it's more like your time is up pal!
- Murder-Suicide: How Hector takes both Tyrus and Gus out.
- No-Sell: Subverted. Gus has just had one of his enemies successfully set off a bomb right in his face. The room is destroyed, but Fring walks out calmly, straightens his tie... then falls over dead, the camera revealing that half his face has been blown off.
- Not So Stoic:
- Look at Jesse's face when he asks about the bomb. He very clearly almost freaks out at Walt.
- Seconds before the bomb goes off, Gus' calm exterior finally crumbles into confusion and panic. His last act is to recompose himself from this, stoic to the bitter end.
- OOC Is Serious Business: Hector looking at Gus clearly freaks Gus out, not to mention the bell spam.
- Oh, Crap!: Gus practically soils his pants when he realizes Hector is but a mere moment away from blowing him to hell.
- The Only One Allowed To Kill You: Tyrus offers to off Hector himself, alone. After all the history between the two, Gus is having none of that.
- Out-Gambitted: Gus clearly thought he had all his corners covered, and not without any good reason, even putting his men into constant alert status. He didn't account for a babbling cook and a vengeful old man though...
- Pet the Dog:
- Blink and you'll miss it, but the normally petty Tyrus smiles kindly to the old lady he passes when casing the old folks' home.
- Also, his offer to kill Hector himself, in a messed up way. Despite being a jerkass, hes loyal enough to risk detection with a public assassination for Gus.
- Even though Hector previously tried to have him killed, Walt gives him a chance to back out of the plan.
- Blink and you'll miss it, but the normally petty Tyrus smiles kindly to the old lady he passes when casing the old folks' home.
- Properly Paranoid: Walt rushes home to gather enough money to pay off Saul's secretary, but stops the car before reaching the house, fearing that Gus's men may be inside waiting to kill him. So he calls the Whites' neighbor Becky and asks her to go inside the house and check if they left the stove on. As she enters the house, two of Gus's thugs do indeed exit through the backyard and run off.
- Reality Is Unrealistic: Gus's death scene is often cited as one of the few moments the show enters the realm of nonrealism due to the way he casually walks away from the explosion that leaves him looking like Two-Face. Victims of explosions have been known to go into shock and show a surprising amount of calm activity before the brain catches up to the body and they expire — the body goes into shock and essentially disconnects itself from the brain, and it takes an unexpectedly long time for the brain to realize what's going on. While Gus probably wouldn't have been upright for as long as he was, walking away and straightening his tie is well within the realm of possibility. In an actual murder case where a man took an axe to his brain repeatedly, the man managed to make breakfast and die on the porch trying to get his paper, too disconnected from reality to realize his dying state.
- Refuge in Audacity: Not only did Walt decide to bring the bomb with him into the hospital when meeting up with Jesse, but it also very clearly gets stuck to the elevator for a brief moment.
- Red Herring: The ricin cigarette. As it happens, Brock wasn't poisoned that way...
- Revenge Before Reason: Had Gus simply allowed Tyrus to kill Hector by himself, as Tyrus himself had suggested, then all that Hector's suicide-bombing would have achieved would have been killing one of Gus's mooks. Instead, Gus's need to be there and finish Hector off personally proves to be quite literally a fatal mistake.
- Rewatch Bonus / Right for the Wrong Reasons: Factoring in the reveal, it turns out Jesse's accusation of Walt poisoning Brock was wrong on three points: the method of poisoningnote , that Walt did it in revenge against himnote , and that Saul helped poison Brocknote .
- Tragic Keepsake: Hector has in his room the bad eye chain from Joaquin, and a picture of Marco, Leonel and Tuco as children.
- Troll: Hector screws with the DEA once again, even giving Hank a taunting wink as he's wheeled into the elevator.
- Two-Faced: Gus walks out of the explosion, seemingly unharmed, until the camera pans around to reveal that Harvey Dent got off easy by comparison.
- Unflinching Walk: Walt, taking his final form as Heisenberg, does the most spectacular of these in the Season 4 finale when he and Jesse blow up the super meth lab under the laundry. After Walt shouts "Vamonos!" and the employees scatter, they walk away nonchalantly as the lab explodes and smoke starts spilling out in the background.
- Wham Episode: Walter finally kills Gus in an impressive Batman Gambit, concluding the longest story arc in the show to date and signalling a major overhaul of the status quo. On top of that a Twist Ending revealing Walt poisoned Brock and pinned the blame on Gus to bring Jesse back on his side.
- Wham Line: "I won".
- Wham Shot:
- The episode ends with the revelation that Walter had Lilies of the Valley growing in his back yard, more or less proving that he was the one who poisoned Brock, albeit non-lethally, and that he's been playing Gus and Jesse for the entire stretch of the finale.
- Preceded by a wham sound: Gus is about to kill Hector Salamanca, but Hector starts tapping his dinger, which isn't dinging properly. It is revealed that he let Walter strap his bomb on the bottom of Hector's wheelchair and Hector suicide-bombs Gus and his henchman Tyrus to get revenge on Gus for wiping out his family.
- What the Hell, Hero?: Jesse practically has a melt down right then and there when inquiring if Walt brought the bomb into the hospital with him.Walt: (angry hushed voice) What?! Was I supposed to leave it on his car?
- Would Hurt a Child: It's revealed that Brock Cantillo was poisoned by Walt, in an attempt to make it look like Gus had poisoned him, so that Jesse would turn on Gus.
