- ―Chuck McGill.
Charles "Chuck" McGill, Jr. is Jimmy McGill's older brother. He is a named partner at one of Albuquerque's most prestigious law firms, Hamlin, Hamlin & McGill, which he co-founded along with his business partner, Howard Hamlin. A brilliant man who holds himself and others to high ideals, Chuck firmly believes that doing the right thing is the only true path to success.
Chuck suffers from electromagnetic hypersensitivity, an unusual affliction garnered under mysterious circumstances, which makes it challenging for him to lead a normal life.
Throughout the first season, Chuck is seen as a protagonist, up until the penultimate episode, where he is revealed as an underlying antagonist of Better Call Saul, as most of the obstacles Jimmy faces can be traced back to Chuck. Despite this, however - Chuck genuinely loves his brother, but believes his alleged nature makes him unfit to be a lawyer. He serves as the primary antagonist of Season 1, one of the two primary antagonists of season 2 and the primary antagonist of Season 3.
Chuck McGill was born in Cicero, Illinois and was the eldest son of Ruth and Charles McGill Sr. Chuck seemed to have a decent childhood and good relationship with his parents, though it appears that his younger brother Jimmy was favored over him more. Chuck once helped with the finances for his father's store and discovered that Jimmy had stolen money over the years, to his father's disbelief. He eventually became a very successful lawyer and established a partnership with Howard Hamlin, moving to the city of Albuquerque to co-found the law firm of Hamlin, Hamlin & McGill (HHM).
Jimmy was constantly arrested for playing con games, and Chuck got him out of every situation. In 1992, Chuck helped Jimmy avoid charges including property damage, assault, and a possible sex offense. Chuck traveled to Cicero to visit Jimmy at his request through their mother. Jimmy begged for Chuck to use his knowledge of legal loopholes to make the charges disappear. Although originally reluctant, Chuck agreed to help him after Jimmy stated that his life would be over if he did not get out of the situation. Chuck warned Jimmy not to make a fool of him if he got back out, but Jimmy promised to change. ("Nacho").It can be assumed that Chuck convinced Jimmy to move to Albuquerque with him to make a living through legitimate means, giving him a job as a mail room clerk at HHM. Chuck reveals that he was very proud of Jimmy when he finally straightened out. However, when Jimmy became a lawyer, Chuck didn't feel he deserved it and sabotaged his chances of getting a job with his firm ("RICO") ("Pimento"). At some point, Chuck was married to Rebecca McGill, a famous violinist whom he seemed to have a decent marriage with, however they are now divorced as Jimmy confirms that Rebecca left Chuck ("Witness").
During the following years, Chuck started suffering from electromagnetic hypersensitivity, causing him to leave HHM in early 2001. He started living in an electricity-free home, relying on gas lamps for light. Before entering the house, visitors have to place all of their electronics in the mail-box and "ground themselves" (remove the static charge from their body). Chuck is sometimes seen wearing what Jimmy calls a "space blanket," presumably to shield himself against static electricity ("Uno").
After being house-ridden for a year and a half, Chuck begins receiving checks for $26,000 from HHM. Jimmy thinks it is in Chuck's best interest to buy out his part of the company ($17 million), as he believes that Chuck will not be returning to work due to his illness. However, Howard wants to continue paying Chuck long term, saying that it is an "extended sabbatical". On his way out, Jimmy is followed by Howard, who tries to pass along some documents for Chuck, which Jimmy declines ("Uno").
Jimmy goes to visit Chuck, who insists he’s going to get better and return to HHM. Chuck rejects Jimmy’s pleas to demand a buyout from his partners, objecting that the firm would probably have to liquidate to raise that much cash, putting more than a hundred people out of work. Jimmy tells him his public defender work isn't going to keep both of them afloat, which just results in a lecture from Chuck about how the experience of helping people is more important than money. Chuck reveals that Howard stopped by and gave him a check for $857, the first of a new weekly stipend ("Uno").
When Jimmy comes home drunk and dropped on the couch, Chuck is disturbed to see that he didn't leave his phone in the mailbox, which he does normally. Chuck has to pick up the phone with tongs and throw it out of the house to feel better. Chuck also sees that Jimmy has with him a hospital bill he paid for broken legs of the twins, Lars and Cal.
The next morning , Jimmy wakes up and sees Chuck sitting near him, wrapped in his "space blanket". Realizing that his brother has seen the hospital bill, Jimmy promises that he isn't returning any customs from the past (referring to Slippin' Jimmy). Jimmy then asks for Chuck to take off the "space blanket". Chuck reluctantly takes it off, only to put it back on when Jimmy leaves the room ("Mijo").
Jimmy arranges a publicity stunt in which he pretends to save a worker from falling off his own billboard. As planned, Jimmy is regarded as a hero and is featured in an article in the Albuquerque Journal. Jimmy visits Chuck, but hides the newspaper that reported the "rescue" to keep him from seeing it. Chuck congratulates Jimmy on his new success, but is oblivious to the stunt. Chuck notices that one of his daily newspapers is missing, which Jimmy dismisses. After Jimmy leaves, a suspicious Chuck painstakingly hurries to his neighbor's house and collects their copy of the Journal, in which Chuck reads about the stunt ("Hero").
Chuck's theft of the newspaper does not go unnoticed, leading the police to lay siege to Chuck's house. Due to his condition, Chuck insists they leave behind all electrical equipment, to which they knock down the door and taser him. Chuck is taken to the hospital and panics when he wakes up surrounded by electrical equipment. Jimmy arrives and disables to surrounding equipment to restore him to full consciousness. He tries to explain his electromagnetic hypersensitivity to Chuck physician, Dr. Cruz, but she is tells Jimmy that his condition is a mental problem.
Upon returning home, Chuck confronts Jimmy about the publicity stunt. Realizing he can't go on living like he does, and that he must overcome his condition to return to work, Chuck begins building up a tolerance to electromagnetic fields by trying to stay outside for as long as he can bear. By the time Jimmy arrives to deliver groceries and paperwork, he is able to stand outside for a solid two minutes. Jimmy leaves behind boxes of paperwork related to a case he is building against the Sandpiper Crossing nursing home, knowing Chuck will impulsively sort them.
Deciding that Jimmy has a solid case against Sandpiper for overcharging residents, Chuck becomes Jimmy's co-counsel and assist him in the case. While meeting with Sandpiper's attorneys, Jimmy presents evidence that the company engaged in illicit interstate commerce, making them eligible for a RICO lawsuit. Chuck demands that Sandpiper Crossing pay $20 million in settlement fees, which the attorneys refuse. Invigorated by the case, Chuck convinces Jimmy to refer the case to HHM due to its sheer size, to which Jimmy reluctantly accepts. The night before their planned meeting with Howard, Chuck secretly sneaks outside while Jimmy is sleeping and uses his phone to make a call to someone.
The next day, Chuck is welcomed back by his colleagues at HHM. Howard offers to give Jimmy a monetary reward for the Sandpiper case, but still refuses to let him join HHM. The next day, Jimmy confronts Chuck with his discovery that Chuck phoned Howard the night before their meeting. Jimmy deduces that Chuck called Howard to cut him out of the case, and that Chuck has been keeping him out of HHM since the beginning. Chuck admits that it's all true, stating that Jimmy is not a "real lawyer" and has not changed from his days as a con man. Feeling hurt and betrayed, Jimmy cuts ties with him despite Chuck's pleading for him to come back in the house.
Chuck is last seen being delivered groceries from an HHM employee and giving up a large box of case files. Chuck sees Jimmy sitting outside in his car, and slowly prepares to open the door to go out and speak with him. Jimmy drives away before this can occur, leaving Chuck disappointed.
Upon being informed by Howard that Jimmy has been hired by the law firm of Davis & Main, Chuck feigns excitement. During a meeting between HHM and D&M concerning the Sandpiper case, Chucks sits in to "bear witness" as Jimmy argues on behalf of his clients.("Cobbler") During a later meeting, Chuck questions whether Jimmy used illegal methods to solicit new clients in the case.("Amarillo")
When Jimmy gets in trouble at D&M for broadcasting a tacky TV commercial without the firm's approval, his friend Kim Wexler -- who had vouched for Jimmy on behalf of HHM -- is demoted to document review, a.k.a. the "corn field." Jimmy promises to quit law in exchange for Kim being reinstated, but Chuck doesn't take the bait.("Gloves Off") During a meeting with Kim, Chuck blames Jimmy's childhood theft for the demise of the store in Cicero and the death of their father shortly afterwards. Chuck allows for Kim to be reinstated.("Rebecca")
Kim resigns from HHM to launch twin solo firms with Jimmy, and secures Mesa Verde Bank and Trust as her exclusive client. Alarmed, Chuck summons Mesa Verde's legal team to HHM without turning off the office's power beforehand. Though he manages to persuade Mesa Verde to keep HHM, he collapses from the EHS exposure. Wanting to get back at Chuck, Jimmy visits his brother and, while he is asleep, photocopies his Mesa Verde files and doctors the address information before they are mailed to the state regulator.("Fifi")
During a hearing before the New Mexico Banking Board, confusion over the address leads to a six-week delay for Mesa Verde. Chuck's insistence on deflecting blame for what seems to be his mistake frustrates Mesa Verde's staff, leading them to fire HHM and return to Kim. Chuck correctly suspects that Jimmy is behind the fiasco, and summons both Jimmy and Kim to lay out his allegations. Although she knows that Chuck is telling the truth, Kim decides to reject his claims and instead charges that his lack of faith in Jimmy caused his pattern of misbehavior in the first place. Chuck later visits the shop where Jimmy copied the files and becomes increasingly angry when the clerk (who Jimmy bribed) denies any wrongdoing. Overwhelmed by his emotions and his EHS, Chuck hits his head and loses consciousness.("Nailed")
Jimmy blows his cover by barging into the shop to come to Chuck's aid. At the hospital, Chuck asks Jimmy why he was there, but Ernesto, an HHM employee who is working as his personal assistant, covers for him. When Jimmy later asks why, Ernesto remarks that Chuck is obsessed with taking Jimmy down. Chuck is overwhelmed by the electricity as he is examined at the hospital, leading him to go through self-induced catatonia when he awakes.
When Chuck returns home, he covers the entirety of his living room in foil, ostensibly to keep out more electromagnetic signals. Chuck also expresses disillusionment with himself for his "mistake" with the Mesa Verde files. Feeling guilty about Chuck's low self-esteem and worsening condition, Jimmy admits all of Chuck's accusations about the Mesa Verde files were true. However, unbeknownst to Jimmy, Chuck has faked his behavior to induce Jimmy into confessing, which he has recorded on audiotape.("Klick")
Immediately after Jimmy makes his confession, Chuck begins removing the foil from his living room walls. While Jimmy is helping him, he comes across an old copy of The Adventures of Mabel, a children's book which was read to him by Chuck when he was little. The two brothers engage in brief childhood nostalgia before Chuck cuts it short, stating that he will never forgive nor forget what Jimmy has done.
Later, Chuck plays the tape of Jimmy's confession to Howard. While angered by Jimmy's actions, Howard explains that the tape can't be used as evidence against Jimmy, nor could it be used to win back Mesa Verde. Chuck suggests that he has something else in mind. Later, when Ernesto drops off groceries and changes the batteries to the tape recorder, Chuck makes it so that he "accidentally" overhears Jimmy's confession. Chuck pressures Ernesto to not tell anyone what he heard on the premise of confidentiality.("Mabel")
Predicting that Ernesto will tip off Jimmy about the tape, Chuck hires a private investigator named Dave to wait for Jimmy to break in and steal it "under cover of darkness." However, after Jimmy learns about the tape from Kim, he angrily drives to Chuck's house in broad daylight, breaks down his door, pries open his desk drawer, and rips apart the tape in Chuck's face. However, Chuck comes out with the upper hand as Howard and Dave make their presence known, having just witnessed Jimmy committing a crime.("Witness")
Chuck is a brilliant man of high ideals; he believes that doing the right thing is the true and proper route to success. Chuck is a highly intelligent and dedicated lawyer who views the law as being sacred and is very determined in helping his clients in any way possible. He is well respected by his colleagues at HHM and also other prestigious law firms.
In contrast to his younger brother Jimmy however, Chuck appears to be a less likeable individual and is not as humorous as Jimmy, and is somewhat uptight and serious. Despite this, Chuck appears to view himself as being superior to his brother and that he does not deserve to be a lawyer due to the simple steps he took to become one. Although Chuck does care for his brother, it is very apparent that he loathes him for many reasons. He views him as being nothing more than a conman who has not changed at all since his "Slippin Jimmy" days and that the way he obtained a law degree was a joke and also hates how he is able to win people over so easily such as his ex-wife and even their own parents. It is hinted that Chuck is jealous of Jimmy to a degree which may be another contributing factor to why he always tries to cut him down in order to prevent him from surpassing himself at feats that he worked hard at to accomplish.
Even though Jimmy himself took care of Chuck for almost a year and half while suffering with his condition, Chuck has not changed his opinions on him at all and went to extreme lengths to prevent him from working at his law firm, even after Jimmy found and built a strong legal case. This incident also shows that Chuck would rather sacrifice a potential multi-million dollar case for HHM than to have Jimmy work at his law firm. Chuck also does not appear to care much for the well-being of others who are affected by his attempts to cut Jimmy down, noticeably Kim. Chuck firmly believes that he is protecting people from getting hurt by sabotaging Jimmy's attempts to be a successful lawyer as he claims people will get hurt if the power of law is abused.
Chuck is also shown to be rather cold toward his younger brother on many occasions such as lying to him that their mother spoke any last words before her death (she called for Jimmy) and brutally telling him of how he is not a real lawyer and that "Slippin Jimmy" with a law degree is nothing short of dangerous. Chuck is also shown to be a hypocrite to a degree as seen when he snaps at Jimmy for stabbing him the back, all the while completely ignoring that he has stabbed Jimmy in the back and betrayed him numerous times.After Chuck correctly deduces that Jimmy sabotaged his Mesa Verde files in order for the case to be returned to Kim, and was completely humiliated as a result, he embarks on a warpath against him to bring him down once and for all. Chuck has been shown to possess a rather ruthless side to a degree as he cunningly gets Jimmy to confess to the deed in private while pretending to feel remorse for his "mistake" and overcoming his electricity condition to record it on tape, showing that Chuck will go to extreme lengths to succeed at his goal.
