In Better Call Saul's series finale, Walter White of Breaking Bad made an observation that Saul Goodman would prove wrong in the end. As Walt and Saul awaited relocation, they hid in an underground bunker owned by Ed "The Disappearer" Galbraith. Seemingly at random, Saul asked Walt what he would do if he had a time machine. After he belittled Saul for the impossible logistics of time travel, Walter said that he'd go back to the time before he was forced out of Gray Matter, the company he co-founded. "What about you," Walt prompted, "Regrets?" Saul responded with a story of his first slip and fall and how he inadvertently injured his knee. Walt stared at him and then said, "So you were always like this?" He dismissed Saul as being petty and money-grubbing, just as many characters in the Breaking Bad/Better Call Saul universe had dismissed him.

Slippin' Jimmy was a good-natured, wildly creative con man. Growing up in Chicago with his older brother Chuck, Jimmy had no real ambitions, no drive to do more than run hustles. An unfortunate incident involving a body function and an open sunroof landed Jimmy in legal trouble. He had hit bottom. With Chuck's help, Jimmy left Chicago and took a job in the mailroom at Better Call Saul's Hamlin, Hamlin & McGill, Chuck's law firm. Even after Jimmy took correspondence courses, and received a law degree from a diploma mill, he still could not shake his love of money and the thrill of the scam. He liked it, and he was good at it.

Time machine references popped up in Better Call Saul's season 6, and particularly so in the finale. Early in episodes 1 and 2, a paperback copy of The Time Machine by H.G. Wells was seen, first in Saul's house as it was being cleared, and second in Kim and Jimmy's apartment. This same book was with Chuck in a flashback scene in the finale. Jimmy was preoccupied with time travel and asked both Walt and Mike what they would do. Walt pointed out that what he was really talking about was regret. Mike, in Better Call Saul, upon being asked, stated that he would go back to the day he took his first bribe because all subsequent bad decisions stemmed from this one. With both Walt and Mike, Jimmy was unable to respond appropriately. He wasn't ready yet.

On Better Call Saul, Kim Wexler was the only person to see who James McGill really was. Her love for him provided the drive for Jimmy to want to be a better person, though he still couldn't resist a good swindle. On several occasions, Kim even participated in the scams. She enjoyed the thrill of it, until one hustle went too far. She and Jimmy witnessed Howard Hamlin get shot in the head, a situation that came about as a direct result of the smear campaign they had launched against him. Her moral compass couldn't take anymore, and Kim ended it with Jimmy and left town.

In the flashback scene with Chuck, he told Jimmy that if he isn't happy with where he was headed, he could always change his path. This uncharacteristic tenderness from Chuck, in the context of Walt and Mike and the time machine question, hit Jimmy hard. When he learned that Kim had revealed the truth about Howard's death to set herself free, he knew what he had to do. With a seven-year plea deal at stake, Jimmy addressed himself to the judge and said, "The name's McGill. James McGill." He then, in the first truthful act of his life, confessed to his involvement with Walter White and the death of Howard Hamlin. He did so to save Kim and himself. He was now free of Saul Goodman and all he represented. In the Better Call Saul finale, he had unburdened himself, and in doing so, proved Walter White wrong.
