While the most beloved supporting character on Breaking Bad was probably Saul Goodman (Bob Odenkirk) himself -- hence him getting a spinoff -- easily the supporting character Breaking Bad fans most loved to hate was drug kingpin Gus Fring (Giancarlo Esposito). Walter and Jesse began working for Gus as meth cooks about halfway through the series run, and the lead duo quickly discovered that their new boss was not a man to be trifled with. This was a fact Walt came to know quite well, once he succeeded in getting on Gus' bad side.

Despite Gus' status as a featured antagonist for a large chunk of Breaking Bad's run, very little was revealed about his past prior to reaching the top of the New Mexico drug world. What exactly drove Gus to become the merciless murderer he was by the time he met Walt and Jesse? These are questions it looks like fans might very well get some answers to during season 3 of Better Call Saul, AMC's acclaimed Breaking Bad spinoff.

With Saul's big premiere just about a month away, AMC -- via EW -- has released a brand new trailer for season 3, including lots of never-before-seen footage. Gus pops in right at the end, at the helm of his Los Pollos Hermanos front business, complete with smile that's just a bit too artificially cheerful. Check out the full video above.

In addition to offering fans their first look at Gus' introduction into the Saul world, the above trailer also makes clear that Chuck (Michael McKean) indeed uses the recorded evidence he has against Jimmy to try and get his brother locked up, with Jimmy seen sporting an orange jail jumpsuit. That said, Jimmy in jail doesn't necessarily mean that he has been convicted of anything in court, as that scene could very well take place while an arrested and charged Jimmy -- or a Jimmy awaiting a sentencing hearing -- is being held in custody pending bail or a resolution of the case.

One assumes Jimmy must not spend too much of season 3 in the slammer, though, as he is also seen meeting up with Mike (Jonathan Banks), presumably preparing to tackle some kind of problem. In an act seemingly wildly out of character, stuffed shirt lawyer Howard Hamlin (Patrick Fabian) is also seen clumsily jumping a fence, which also begs the question of what might compel him to try and become a man of action. It's been established that he actually likes Jimmy personally, so it's not unimaginable that he's unwilling to abide Chuck's harsh revenge tactics.
