Given the events of Breaking Bad, as well as all the antics of the characters in Better Call Saul, it’s only natural that many of these morally ambiguous characters would ponder the notion of regret, as Entertainment Weekly points out. For some characters, this theme manifested itself in subtle ways. Mike Ehrmantraut (Jonathan Banks) accepted his criminal impulses without losing sight of the difference between right and wrong. This allowed Mike to look back on his choices with regret while also coming to terms with his true nature.
The episode begins with an unseen flashback to the events of Season 5 Episode 8, “Bagman.” Saul and Mike are in the desert trying to get the money back to post Lalo Salamanca’s (Tony Dalton) $7 million bail. The two stop at a waterhole in the desert to rest and Saul asks Mike what date he would like to travel back to if he had a time machine. Mike says he would go back to December 8, 2001, which is believed to be the time his cop son was murdered by his coworkers, but changes his answer to a date in 1984, the day he took his first bribe and started becoming a dirty cop himself. The implication is that Mike would not take the bribe and therefore would avoid a life of crime. When Mike returns the question to Saul, he simply replies that he would travel back in time to steal lucrative ideas from inventors in order to get rich.
