Last week’s episode ended with Mike Ehrmentraut shaking hands with Gus Fring – forging a key link that will, in time (and in Breaking Bad), lead to their unlikely and sometimes uneasy partnership in the drug trade. Last week’s episode also showed Jimmy McGill painting himself out of a financial corner by becoming “slippin’ Jimmy,” another famous step in his evolution, or devolution, to the amoral Saul Goodman. Like Breaking Bad, Better Call Saul is one of the best extended character studies in TV series history.
