A throwaway line from Saul Goodman’s introduction inBreaking Badended up paving the way for the creation of two ofBetter Call Saul’s greatest characters. Saul was first introduced inBreaking Badseason 2, episode 8, “Better Call Saul.” After Badger was arrested by an undercover cop for selling meth on the street, Walt and Jesse hired Saul to represent him. This episode established Saul’s penchant for less-than-legal schemes, as he brought in a career inmate to pose as Heisenberg, but it didn’t reveal much else about him.

For the next fourseasons ofBreaking Bad,Saul existed mainly as a comic relief character. He facilitated plot points like money laundering and Walt’s working relationship with Gus Fring, but his primary function was to spout quippy one-liners.When Saul got his own spinoff,Better Call Saul, he was expanded into every bit the complex, three-dimensional antihero that Walt was.Better Call Saulgave audiences a chance to get to know Saul — or, rather, Jimmy McGill — in much more depth than they did inBreaking Bad. ButBreaking Badlaid the foundation.

When Saul was reluctant to take Walt’s bribe and have Badger lie under oath, Walt and Jesse kidnapped Saul outside his office and drove him out to the desert. They knelt him in front of an open grave and held a gun to his head to intimidate him into taking the job. Saul’s immediate response was to say,“It wasn’t me! It was Ignacio, he’s the one!”They had no idea what he was talking about, soa confused Saul asked if Lalo sent them. When Walt started coughing, Saul realized who he was.

Saul’s firstBreaking Badepisode, “Better Call Saul,” originally aired on AMC on June 28, 2025.

At the time,the Ignacio/Lalo reference was just a throwaway line to suggest that Saul has made a lot of enemiesin his career as a criminal lawyer. But when it came time to give Saul his own spinoff, Vince Gilligan and Peter Gould used that throwaway line as an opportunity to create two of theBreaking Baduniverse’s greatest characters. In just its second episode,Better Call Saulintroduced Ignacio “Nacho” Varga as an enforcer for the Salamanca cartel. In its fourth season, the spinoff introduced Lalo Salamanca as one of the cartel’s leaders.

What If Lalo Salamanca Hadn’t Died In Better Call Saul & How It Would’ve Changed Breaking Bad

Lalo Salamanca’s death in Better Call Saul set the stage for several key plot points to unfold in Breaking Bad — but what if he’d survived?

Played by Michael Mando,Nacho was one of the most likable characters inBetter Call Saul. He just wanted his dad to be safe, which drew him deeper and deeper into a life of crime. He was forced to keep working for the Salamancas as a double agent for Gus. He had a compelling arc that built to a tragic ending.Lalo, on the other hand, was a despicable villain; a cold-blooded, psychopathic killer with no capacity for empathy. But thanks to Tony Dalton’s performance,Lalo was also oddly charismatic — and endlessly watchable.

A Lot About Jimmy McGill’s Story In Better Call Saul Was Established In Breaking Bad

“My Real Name Is McGill”

Since Saul only appeared inBreaking Badin a professional capacity in relation to Walt and Jesse, very little of his personal life was shown. He was seen whenever Walt needed to get in touch with a freelance crook or Jesse needed to get out of a police interrogation room.Breaking Badnever made any mention of Saul’s rivalry with his late brother Chuck, his longstanding love for Kim Wexler (except for a couple of glib ex-wife jokes), or the elaborate series of pranks that led tothe death and disreputation of Howard Hamlin.

When Walt first hired Saul, he confessed that Saul Goodman isn’t his real name; he told Walt, “My real name is McGill,” and that the Saul persona is an act. This dual identity would become the dramatic crux of Better Call Saul.

But in spite of this,Breaking Badstill laid most of the groundwork for Jimmy’s story inBetter Call Saul. Saul’s one-liner about how he convinced a woman he was Kevin Costner became a great gag inBetter Call Saul, andhis joke about managing a Cinnabon in Omaha formed the basis ofBetter Call Saul’s black-and-white flash-forwards. When Walt first hired Saul, he confessed that Saul Goodman isn’t his real name; he told Walt, “My real name is McGill,” and thatthe Saul personais an act. This dual identity would become the dramatic crux ofBetter Call Saul.
