Chuck was right about you all along. He's mentally ill. What is your excuse?
|― Rebecca to Jimmy after he refuses to help Chuck.|
In a flashback set in 1992, Rebecca and a hypersensitivity-free Chuck prepare dinner. Chuck apologizes in advance for the guest they’re expecting: Jimmy, whom he describes as “an acquired taste.” Rebecca isn't worried, but they come up with a plan in which she will tug on her earlobe if she tires of Jimmy's antics and wants to end dinner early. The couple is interrupted by the doorbell. Six-pack of beer in hand, Jimmy looks at the house in awe. Chuck impatiently invites him inside.
Over dinner, Chuck boasts about Rebecca's impressive career as a concert violinist. When Jimmy awkwardly brings up their wedding, Rebecca kindly changes the subject and asks Jimmy about his first week in the mailroom at HHM. The conversation lulls to an uncomfortable silence, so Jimmy begins telling lawyer jokes. Rebecca smiles, genuinely amused. As Chuck heads to the kitchen to retrieve dessert, she jumps in with a joke of her own. Rebecca and Jimmy dissolve into hysterics, both too preoccupied to notice Chuck pulling at his earlobe, his fake smile beginning to falter.
While reading in bed later that evening, Rebecca tells Chuck that he shouldn't have worried so much. As she turns back to her magazine, Chuck takes a crack at a lawyer joke of his own. It falls flat. Rebecca humors him with a polite chuckle, then resumes reading. Chuck stares straight ahead, jealous of Jimmy’s natural charm and the effect he had on Rebecca — one that Chuck couldn’t replicate.

In a flashback, Rebecca visits Chuck, who she is separated from, at his house where he now suffers from electromagnetic hypersensitivity. Chuck goes to great lengths to hide his condition from Rebecca and forbids Jimmy to tell her as Chuck has no wish to burden Rebecca with his issues. However, during dinner, Rebecca's phone rings and she holds a conversation with her conductor, causing Chuck pain. Rebecca is unable to understand Chuck's erratic behavior and departs in a taxi after he knocks her phone from her hand, refusing Jimmy's offer of a ride.
In the present, Rebecca arrives at Jimmy's disciplinary hearing before the New Mexico Bar Association to the shock of Chuck who thinks its a way of getting at him by Jimmy. Having been told of Chuck's EHS by Jimmy, Rebecca expresses her sympathy for Chuck and sorrow that he didn't simply tell her earlier. Chuck claims that he wanted to spare her the knowledge of his condition and she stays to watch the proceedings. On the stand, its revealed that Chuck developed EHS shortly after his and Rebecca's divorce and Jimmy suggests that it was a result of the divorce. After Jimmy reveals that he had Huell Babineaux plant a fully-charged cell phone battery on Chuck for nearly two hours, Rebecca watches in horror as Chuck implodes on the stand and confesses his resentment for Jimmy and his desperation to get Jimmy disbarred. Apparently unable to watch, Rebecca covers her face with her hand partway through Chuck's rant and even sheds some tears. ("")
Rebecca takes a taxi to Chuck's house, but Chuck, devastated by the outcome of his scheme against Jimmy, does not answer the door. While Jimmy and Kim celebrate the verdict at Wexler McGill, Rebecca drops by the office and tells them that she spent an hour trying to talk to Chuck. Rebecca pleads with Jimmy to make amends with Chuck, reasoning that he is mentally ill and vulnerable, but Jimmy tells her that he no longer regards him as his brother. Rebecca realizes that Jimmy never brought her to Albuquerque to help Chuck as he claimed, and bitterly tells him that Chuck was right all along even though Jimmy had been taking care of Chuck for a whole year and had just been pitted against him in a court case.

A grief-stricken Rebecca attends Chuck's funeral, crying throughout. Seeing Rebecca's state, Howard hands her a tissue and takes her hand to appease her. ("")
When Kim arrives at Howard's office, he is with Rebecca signing paperwork regarding Chuck's estate. Howard reveals that Chuck left the house to Rebecca and as the executor of Chuck's estate, he intends to liquidate it. Howard and Rebecca both agree to allow Jimmy to go through the ruins of the house and take whatever he wants for himself and Rebecca watches as Howard explains what Jimmy gets from the estate before leaving when Kim asks to talk to Howard alone.
