After drawing audiences in for years with the premise of tying into the events of Breaking Bad, Better Call Saul forged its own identity outside of Breaking Bad. Better Call Saul has become one of the few shows set in the same universe as a "bigger" show to match if not exceed the original.
Having said that, the sixth season of Better Call Saul is going to be the series' last, and AMC just dropped the first full-length trailer, teasing the full evolution of public defender Jimmy McGill to the skeevy, street-smart lawyer, Saul Goodman.
Most prequels tend to telegraph their endings by design. Since we already know what's going to happen next, the prequel becomes more predictable as they get closer to the key events of the original. But, this isn't the case for Better Call Saul. Even the several key figures and relatively minor characters from Breaking Bad make an appearance, Better Call Saul has also introduced its own set of interesting characters. Case in point, Reha Seehorn's Kim Wexler, who is the girlfriend of Bob Odenkirk's Jimmy and later wife.
Because Kim is never mentioned nor seen during the events of Breaking Bad, most assume that she'll die in the finale. However, from what we've seen in Better Call Saul, things don't always turn out the way they do, suggesting that there could be a twist.
