AMC unveils a new Better Call Saul season 6 trailer ominously teasing a happy ending for the show. Created by Vince Gilligan and Peter Gould

Over five and a half seasons, Better Call Saul has chronicled Jimmy McGill's slow descent from an earnest court

appointed lawyer to the unscrupulous criminal defense attorney eventually introduced in Breaking Bad season 2: Saul Goodman.

Better Call Saul also explores Jimmy's connections to the Juarez drug cartel, as well as retired police officer Mike Ehrmantraut,

who undergoes a similar moral decline as he becomes right-hand man to the Los Pollos Hermanos owner and narcotics distributor Gus Fring.

culminating in a devious plot to ruin fellow attorney Howard Hamlin that results in deadly unintended consequences in the Better Call Saul mid-season 6 finale.

All things considered, the trailer's happy ending tease is likely a simple marketing ploy rather than an actual indication of what's to come.

For the characters whose lives haven't ended in downright tragedy, the writers usually opt for bittersweet conclusions to character arcs, and the same should be expected for Better Call Saul.
