Walter White and Skyler White frantically pack their luggage in their bedroom and discuss preparing Walter White Jr.'s belongings. As DEA agents arrive at the White Residence to take them into protective custody at Hank and Marie Schrader's, Walt tells Skyler that the hitman is after him, not Hank and that his presence will only make the situation more dangerous. Skyler frantically asks Walt, "How long till you're safe. 'Till you''ve worked it out?" Walt can only answer, "There was a way out. But not any longer." She very reluctantly leaves him behind as she takes the baby to her sister's.
Walt sits at home, alone, with his .38 snub at his side, anticipating the worst. He mulls over his options, spinning the gun three times on its side as he does so. The first two times the barrel of the gun stops pointing straight at Walt, while the third points at his nearby flowerpot wherein a lily-of-the-valley is planted. Walt continues his musings in sullen, hopeless silence.
At the Schrader residence, Walter White Jr. complains that Skyler White didn't do enough to convince Walt to come, and that his father is too stubborn to realize his own life is more important than a car wash. Hank calms everyone down and convinces Steven Gomez that his wild goose hunt against Gustavo Fring led to the death threat. Gomez, tired of being badgered, finally agrees to investigate.
Gomez arrives at the industrial laundry and talks the foreman into letting him search the facility - now, with just two men, or later when he comes back with a warrant and twenty officers. When the foreman agrees, Gomez brings out a drug dog to sniff out the place, but to no avail. Beneath the facility, Jesse Pinkman and Tyrus Kitt wait silently. Gus calls Jesse and tells him that this is why he couldn't trust Walt. Jesse says he sympathizes, but again insists if anything serious happens to Walt, he won't cook. Gus answers that he'll make an appropriate retaliation and hangs up. Gomez leaves, with just some photographs, and Jesse continues his cook. Later, a laundry truck drops Jesse off by his car parked on the side of an abandoned street. He attempts to call Walt with no success but does check his voicemail only to find several panicked calls from Saul Goodman.
He goes to Saul's office where his new bodyguard Huell Babineaux pats him down for weapons. Saul gives Jesse the rest of his money that he had stored, and tells him that he is hitting the road because he fears for his own safety after Gus threatened Walt's entire family. Jesse is shocked at the news, wanting to know when this threat happened. Hank frustratingly looks at the "squeaky clean" photos from the industrial laundry, upset that the investigation led to no avail. Skyler tries to offer him silent condolences, and steps outside to smoke a cigarette.
Jesse sits on his couch at home, thinking over the intense developments of the day. He receives a phone call and rushes to the hospital where Brock Cantillo has been admitted to the emergency room. His condition is getting worse and worse, and when Andrea Cantillo goes in to see him in the pediatric ICU, Jesse steps outside to smoke a cigarette. He notices his cigarette with ricin is missing, in a desperate panic smashes his entire cigarette pack searching, then runs inside to tell Andrea that Brock may have been poisoned with ricin. Andrea begs him to tell her what's going on, but he can only apologize and hurriedly runs off.
At Walt's house, Jesse knocks on the door. Walt has barricaded himself in, but lets Jesse in. They talk about Walt's situation. Walt lays his gun down and as he frantically checks from window to window, Jesse picks it up and points it at him. Walt notices and tries to talk Jesse into lowering the gun, but Jesse is convinced that Walt has poisoned Brock, insisting Walt admit why. Walt talks Jesse through the evidence, attempting to convince him that he would not have anything to gain by killing the child. Suddenly Walt pauses, then falls into panicked laughter as he realizes that Gus has arranged all of this so it would be Jesse who kills Walt. He explains it all and gets Jesse to believe it. Jesse finally lowers the gun and before he leaves, Walt convinces Jesse to help him kill Gus.
That night at the hospital, Jesse continually attempts to enter the ICU, but is stopped by the nurses since Andrea refuses to let him in. The next morning, Tyrus roughly awakens Jesse in the waiting area and orders him to return to the lab to continue his now overdue cooking. He refuses and when Tyrus attempts to strong-arm him into moving, Jesse calls security on him. He then sends a text message to Walt, who is preparing a pipe bomb in his kitchen. Later, Tyrus meets Jesse again in the hospital and tells him Gus is waiting to talk to him. Gus is at first insistent that they're on a schedule, but when he realizes that Jesse might suspect him in the poisoning, he tells Jesse to wait in the hospital for however long Brock needs to recover. Jesse seemingly manages to lie to Gus that he doesn't know how Brock was poisoned.
Gus leaves the hospital and walks toward his car. From a far-off rooftop, Walt holds the detonator and watches with binoculars. As he nears his car, suddenly pauses, moving instead towards the ledge and looks out over the rooftops from the parking garage. He surveys the rooftops in silence, as Walt scrambles down so as not to be seen, puzzled by Gus' actions. Gus ultimately decides to walk away from his car than take the chance. Walt, detonator still in hand, is left wondering how Gus could've possibly known about the bomb - he looks exhausted, panicked and helpless.
- This is the third episode of Breaking Bad to be directed by Vince Gilligan.
- This is the first and only episode to be directed but not written by Vince Gilligan.
- The hospital in this episode sports a nod to the Breaking Bad logo all across its tiled floor.
- In this episode Jesse accuses Walt of poisoning Brock, and Walt gives a highly believable denial, one far more convincing than Walt's ability to lie. It is later revealed (at the end of "Face Off") that he did in fact poison Brock. Bryan Cranston has since said that when he gave this performance, he had not read the script for the next episode and was not told that the denial was a lie.
- Skyler: "Walt, how long till you’re safe, till you can work this out?"
- Walt: "Oh, Skyler. I have lived under the threat of death for a year now, and because of that, I’ve made choices…. I alone should suffer the consequences of those choices, no one else. And those consequences–they’re coming. No more prolonging the inevitable."
- —Walter explaining to Skyler that he is the real target and that he can not just flee.
- Jesse: "Hey–Stop laughing. Stop laughing!"
- Walter: "I have been waiting. I have been waiting all day, waiting for Gus to send one of his men to kill me–and it’s you. Who do you know who’s okay with using children, Jesse? Who do you know who has allowed children to be murdered? Hm? Gus! He has–he has been ten steps ahead of me at every turn, and now the one thing that he needed to finally get rid of me is your consent, and boy he’s got that now. He’s got it. And not only does he have that, but he manipulated you into pulling the trigger for him."
- Jesse: "Only you and I knew about the ricin!"
- Walter: "No! You don’t even believe that–Gus’ cameras everywhere. Please. Listen to yourself. No. He has known everything all along. Where were you today? In the lab? And you don’t think it’s possible that Tyrus lifted the cigarette out of your locker? Come on! Don’t you see? You are the last piece of the puzzle. You are everything that he’s wanted. You’re his cook now. You’re the cook, and you have proven that you can run a lab without me, and now that cook has reason to kill me. Think about it! It’s brilliant! So go ahead. Go ahead. If you think that I am capable of doing this, then go ahead. Put a bullet in my head and kill me right now. Do it! Do it!"
