In a flashback sequence, Hank's DEA informant, Tortuga, holds court at a seedy Mexican cantina. Tortuga receives a birthday present — a large tortoise — from "El Jefe," his boss. Tortuga is delighted with the gift until the boss writes "HOLA DEA" on the reptile's back. The Cousins step out of a back room; one holds Tortuga down as the other cuts off his head with a machete.
Mike, watching Walt from outside his house after the Cousins' clandestine visit, phones to report that he is still alive. Meanwhile, Skyler arrives home to find Walt inside the house. She tells Walt she won't enter until he leaves and threatens to call the police, but Walt insists that he is staying. Skyler dials 911 and asks the dispatcher to send officers immediately. Recalling Saul's advice, Walt stays calm and grades papers as he waits for the police to arrive.
Returning home, Junior is elated to see his father and is angry when he learns that his mother called the cops on him. Skyler tells one of the officers that he is trespassing, but learns because she has not legally separated or divorced from Walt, that Walt has not behaved violently, and that Walt's name is on the lease of the house, he is within his rights to stay in the house. When the officer asks Skyler if Walt has broken any laws, she can't bring herself to respond. When the officers leave without arresting Walt, Skyler coldly welcomes him home.
Jesse sits alone on the floor in his empty house, calling Jane's old cell phone number to hear voice on the voicemail greeting. Saul pays Jesse him, asking him to convince Walt to begin cooking again. Jesse agrees to try, then shows him the door. After Saul departs, Jesse resumes dialing Jane's number.
An unenthused Hank reveals to Gomez that he is wanted back in El Paso. Meanwhile, the Cousins escort Hector Salamanca to a meeting with Gus and Juan Bolsa, Tortuga's former boss. Bolsa explains how Hector's nephew, Tuco, who Hector raised as his own son and who took over Hector's business, died because of Walt's betrayal. The Cousins demand the right to exact vengeance against Walt on Tuco's behalf. However, Gus requests that they postpone vengeance until his business with Walt is concluded. Privately, Bolsa warns Gus to finish the business with Walt quickly or risk losing the cartel's favor. As for the Cousins, Bolsa can't guarantee they'll listen to him and delay their revenge.
Walt, sleeping on the floor of Holly's bedroom, wakes up when he hears his daughter crying in Skyler's room. Walt asks if he can come in and help, but Skyler doesn't respond. When he asks to use her bathroom, she remains silent . Frustrated, Walt urinates in the kitchen sink. Later, Skyler updates her divorce lawyer about Walt's return home. The lawyer encourages Skyler to give her all of the facts, reminding Skyler that attorney-client privilege ensures the confidentiality of anything she discloses. After contemplating, Skyler admits that Walt is a meth cook. Skyler's lawyer encourages her to immediately sue for divorce, but Skyler expresses reluctance, reasoning that she doesn't want her son to find out that his father is a criminal when Walt may eventually die from his cancer anyway.
At a dive bar, Hank tells Gomez that errands and packing are delaying his return to El Paso. Hank fights back an anxiety attack in the bathroom, then leaves to stash his gun in his SUV. Returning to the bar, Hank picks a fight with two "dirt-balls," repeatedly bashing one man's head against the floor before finally identifying himself as DEA.
A forlorn Jesse repeatedly calls Jane's voicemail until he hears a new message that her number is no longer in service. He is crushed at the loss of the very last remnants he has of Jane. The next morning, Jesse drives the RV into the desert, determined to start cooking again. Meanwhile, at home, Walt leaves a duffel bag stuffed with cash in full view. He asks Skyler if they can talk when she discovers it.
At DEA field office, Gomez tells Hank that ASAC Merkert wants to see him. As far as Merkert knows, the suspects attacked Hank while Gomez was outside, calling for backup. Gomez tells Hank that he didn't mention in his report "that you left your gun under the car seat before you went back inside."
Back at home, Walt reasons with Skyler that this money will put their kids through college and cover the mortgage and other expenses after he's gone, something she could never afford on a part time bookkeeping salary. Skyler glowers at Walt accusingly, listens to him, but utters not a word.
At Beneke Fabricators, Skyler approaches Ted in the breakroom and seductively touches his shoulder. They kiss surreptitiously, after which Skyler asks whether his kids are home. When Skyler returns to the White residence that evening, Junior and Louis Corbett are watching TV while Walt cooks a pot-roast. Walt is eager to hear how she feels, after their talk. Skyler coldly tells him that, "I fucked Ted" -- her only course of revenge. Skyler calls the boys down to dinner, leaving a wounded Walt standing speechless in the kitchen.
- The animated show that Walt Jr. and his friend are watching is an episode of Aqua Teen Hunger Force from season six titled: "Chick Magnet." The character on screen was Master Shake.
- The "I.F.T" of the title is an acronym for "I fucked Ted", which Skyler quotes at the end of the episode.
- The initial airing of the episode censored the word "fucked," although it can be heard on the DVD release
- It is also a parallel with the title "", which can also be read as the acronym ICU, referring to the Intensive Care Unit where Hank Schrader and Marco Salamanca are being treated after the attack in "".
- The T in the title could also be a reference to Tortuga, who also gets "fucked" (i.e. beheaded) by the Cousins during the cold open
- The seconds hand on the clock over the copy machine at Beneke Fabricators is not moving.
- One of the "dirt-balls" Hank gets into a fight with is played by mixed martial artist, Keith Jardine, who formerly fought in the UFC.
- Tortuga was killed by a machete, a possible nod/reference to the Danny Trejo movie Machete.
- The car the Cousins steal to transport Hector from Casa Tranquila to the meeting is a 2006 Toyota Sienna.
- This 'S3.03' ep. the Salamanca/Gus meeting on Gus's turf is mirrored in End of Days and finally Face Off (at the end of S4) on Hector's turf - Rm '303' of the nursing home - this time it is Gus that says "Blood must be repaid by blood." Again, but with the last word, Hector rings his bell furiously in their final 'face off.' [BLAM]
- The owner of the transport van, the redhead lady with the black glasses who says "Hello" to the Cousins is famed casting director Shari Rhodes, who passed just months before this episode aired. This episode ends with a dedication credit to her.
- Tortuga makes a comment in Spanish to the bartender at the beginning of the show. The comment is: "There are two kinds of people in this world: those who pour drinks and those who drink. Now shut up and fill my glass." This comment is reminiscent of the phrase used by Tuco and Blondie in The Good, the Bad, and the Ugly. In that movie, Tuco starts a few statements with the same first words "There are two kinds of people in this world..." and then he finishes the statement with a comment relevant to the situation. At the end of the movie, Clint Eastwood's character, Blondie, mocks Tuco by telling him: "There are two kinds of people in this world, my friend: those with loaded guns and those who dig. You dig."
- Giancarlo Esposito makes a slight mistake in Spanish in the scene when Gus meets with Juan Bolsa and the Salamancas. He misplaces the accent on the word "importará", pronouncing it as "imporTAra" when it should be "importaRA".

- "I’ve done a terrible thing. But I did it for a good reason. I did it for us. That is college tuition for Walter Junior–and Holly eighteen years down the road. That is health insurance for you and the kids. For Junior’s physical therapy, his SAT tutor. It’s money for groceries, for gas, for birthdays and graduation parties. Skyler, that money is for this roof over your head, the mortgage you are not going to be able to afford on a part-time bookkeeper’s salary when I’m gone. This money – I didn’t steal it. It doesn’t belong to anyone else. I earned it. The things I’ve done to earn it, the things that I’ve had to do – I’ve got to live with them. Skyler, all that I’ve done, all the sacrifices that I have made for this family–all of it will be for nothing if you don’t accept what I’ve earned. Please. I’ll be here when you get home from work. You can give me your answer then."
