Warning: Spoilers ahead for Better Call Saul season 6, episode 13Here are all the guest stars and cameos from Better Call Saul's series finale. Describing Better Call Saul's ending as a celebration of all that came before would be disingenuous. With Jimmy jailed for life and Kim facing a huge civil lawsuit, "Saul Gone" is anything but celebratory. And yet this final chapter still succeeds in pulling together the twin worlds of Better Call Saul and Breaking Bad, dropping cameos left and right. Some of these were expected, others arrive completely by surprise, but all of them filter into the gentle redemption of Jimmy McGill, who finally confesses his crimes and takes responsibility for everything from Chuck's death to washing Walter White's cash.

Set around December 2010, Better Call Saul season 6's finale pushes further into the Breaking Bad timeline than ever before, even overtaking Jesse Pinkman's El Camino movie. And with no further projects in Vince Gilligan's pipeline at the time of writing, "Saul Gone" likely marks the final occasion these beloved characters will grace a TV screen.

From the very biggest personalities of Breaking Bad's universe to lesser-known recurring faces, Better Call Saul's final episode draws from every nook and cranny of Vince Gilligan and Peter Gould's lore to bring as much of the gang together as possible in its final chapter (without feeling like the final moments of Lost). These are all the returnees waving farewell to Saul Goodman.

Mike Ehrmantraut (Jonathan Banks)

Jonathan Banks as Mike Ehrmantraut in Better Call Saul

First appearing in Breaking Bad season 2, Jonathan Banks' Mike Ehrmantraut enjoyed main character status until eventually dying by Walter White's hand in the final season. After a flashback cameo in El Camino, Mike joined the main cast of Better Call Saul, which tells his backstory as much as it does Jimmy McGill's. Although Mike's Better Call Saul journey came to an end when the prequel timeline ceased in season 6's "Fun & Games," he guested briefly alongside Bob Odenkirk in "Breaking Bad," flashing back to the day they first discussed Walter White.

It's entirely fitting that Jonathan Banks gets another cameo in Better Call Saul's grand finale. This scene takes place during season 5's "Bagman," when Mike and Jimmy were trekking through the desert. Though his appearance is fleeting, Mike Ehrmantraut's final-ever scene is a poignant one. Asked what he'd do with a time machine, Mike first mentions December 8, 2001. This is presumably when his son, Matty, was killed. Mike then changes his mind to March 17, 1984, which is when he first took a police bribe. If Mike had followed a different path that day, he never would've become a dirty cop, never would've advised his son to do the same, and Matty would still be alive. Mike's final scene in the Breaking Bad universe is wishing he never got involved in any of it.

Bill Oakley (Peter Diseth)

Peter Diseth as Bill in Better Call Saul

Peter Diseth plays Bill Oakley in all six seasons of Better Call Saul, albeit only 13 episodes combined. A prosecution lawyer usually found at the Bernalillo County Courthouse, Bill shared a friendly rivalry with Jimmy McGill, despite often being his courtroom opponent. Their friendship turned to scorn when Jimmy's deal with Lalo Salamanca became public knowledge, and the pair seemingly grew apart through the Breaking Bad years. After Saul Goodman fled Albuquerque, Bill turned from prosecution to defense, assuming his former rival's role as a "bus bench" lawyer. Jimmy took full advantage of Oakley invading his turf by hiring his old pal as co-counsel after getting caught.

Poor Bill doesn't have much to do during Better Call Saul's finale court hearing, with Jimmy insisting on representing himself. In storyline terms, however, Bill helps trigger his client's redemption by telling him all about how Kim bravely confessed her crimes to Cheryl Hamlin, inadvertently inspiring Jimmy to do the same.

Austin Ramey (Todd Terry)

DEA agents in Better Call Saul

Todd Terry's Austin Ramey is easily missed in Better Call Saul's series finale. The SAC of the DEA debuted in Breaking Bad season 2 as Hank Schrader's superior officer, and can also be seen giving a TV conference in El Camino. "Saul Gone" represents Ramey's first Better Call Saul credit, and he's present in both the negotiation and courtroom sequences.

Marie Schrader (Betsy Brandt)

Betsy Brandt as Marie in Better Call Saul

If you had to hit the pause button and ask, "Wait, was that...." then you're probably not alone. Undoubtedly the most surprising cameo of Better Call Saul's series finale belongs to Betsy Brandt, who reprises her role as Marie Schrader from Breaking Bad. The purple-wearing kleptomaniac is a rare example of a main Breaking Bad character who doesn't wind up dead or in hiding, and "Saul Gone" finds Marie still grieving her husband. With Hank's Nazi killers dead, Walter White dead, and Jesse Pinkman missing, Saul Goodman's arrest is Marie's first taste of justice since Breaking Bad ended, and her desperation to see the lawyer rot in jail serves as a stinging reminder of those still picking up Walt's pieces.

When Jimmy invites Marie into the prosecution's meeting room and delivers a scripted speech about how they're both "victims," he's showing everyone just how convincing he can be, and how a jury might be easily conned by his boldness. Betsy Brandt's Better Call Saul comeback also shows just how far-reaching Breaking Bad's big deaths continue to be until the very end, portraying a woman unable to move forward until somebody pays for her husband's death.

Walter White (Bryan Cranston)

Bryan Cranston as Walter White in Better Call Saul

Bryan Cranston already confirmed himself for two Better Call Saul season 6 cameos - one alongside Aaron Paul's Jesse Pinkman, and one by himself. After Walt and Jesse's "Breaking Bad" desert scene, therefore, viewers knew to expect another Walter White sequence in the finale. Set during Breaking Bad season 5's "Granite State," the claustrophobic scene is an extension of Jimmy's earlier conversation with Mike, asking what Walt would do with a time machine. Walt sees through the act and realizes his disgraced lawyer is actually talking about regrets, then goes on to list leaving Gray Matter as the moment he'd most like to change. Unlike Mike, Walt wouldn't travel back to the moment he became a criminal, although the way he glances at the watch Jesse Pinkman bought him implies he does consider this answer.

Wishing he hadn't walked away from Gray Matter proves how deeply Walt desires recognition for his greatness - prestige, glory, rewards for scientific brilliance. He could've had it all... without becoming a meth kingpin. In a final insult to Jimmy McGill that sums up their fractious relationship, Walt cruelly claims "Saul Goodman" would've been the last person he'd pick for legal representation against Gray Matter.

When Jimmy then gives his own answer - a silly story about hurting his knee during a scam - Walt realizes his lawyer has been a crook since the beginning, rhetorically asking, "So, you were always like this?" Walt's line smartly plays into Better Call Saul's ending, where Jimmy drops the habit of a lifetime and does the right thing.

Suzanne Ericsen (Julie Pearl)

Suzanne in Better Call Saul

Julie Pearl makes a handful of appearances as Bernalillo County's assistant DA between Better Call Saul seasons 2 and 6, usually chastising Jimmy McGill or subtly implying Kim Wexler could do better. Suzanne Ericsen also appears briefly in El Camino, where she's on the hunt for Jesse Pinkman. Having always held her in high regard, Suzanne calls to warn Kim that Jimmy will be bringing evidence against her in Better Call Saul's series finale. This turns out to be a ruse, with Jimmy only involving Kim to ensure she attends the hearing and sees him confess. Completely by accident, Suzanne is instrumental in helping Jimmy and Kim find eventual reconciliation.

Blanca Gomez (Marisilda Garcia)Betsy Brandt as Marie and Marisilda Garcia as Blanca in Better Call Saul

Not strictly a return, since Blanca Gomez - wife of Hank's DEA partner, Steve - has never before appeared in Breaking Bad or Better Call Saul. She has, however, been referenced by name on several occasions, the earliest coming in Breaking Bad season 3.

Chuck McGill (Michael McKean)

Michael McKean as Chuck in Better Call Saul

Chuck McGill took his own life in Better Call Saul season 3, but Michael McKean remains so integral to the spinoff's DNA, his appearance in the final episode is a beautifully poetic moment. Set shortly before Better Call Saul, Jimmy is making a supply run for the reclusive Chuck, but kindness quickly turns to bickering as the siblings once again fail to communicate. Chuck asks about Jimmy's legal work (seemingly having a genuine interest), but Jimmy interprets the question as a dig because Chuck doesn't consider him a "proper" attorney. An argument once again ensues, and Chuck leaves Jimmy with one pearl of wisdom: "If you don't like where you're heading, there's no shame in going back and changing your path."

Chuck's Better Call Saul series finale cameo also explains Jimmy's "time machine" conversations with Mike and Walt. Chuck owned a copy of HG Wells' The Time Machine, which passed down to Jimmy after his death. Although he fobs Mike and Walt off with phony answers, the real moment Jimmy would change is the death of his brother.
