Hector confirms for Lalo that Gus is protected by the cartel because he is a top producer of the organization's illegal drug profits. Sticky and Ron, two drug users who received Saul's 50 percent off business card go on a multi-day binge. They purchase numerous bags of cocaine from the Salamanca drug house but the bags get stuck in the drainpipe, which causes them to loudly complain. The police arrive just before Domingo dislodges the drugs. He is arrested and the police prepare to raid the house. Nacho climbs over rooftops to sneak into the house and retrieve the drug stash before police enter. Lalo is impressed with Nacho, but worries Domingo may talk in jail. Mike remains upset over Werner's death and has been drinking. While babysitting Kaylee, he lashes out angrily after she asks for details about her father. Kim is still apprehensive about Jimmy practicing law as Saul Goodman. Jimmy and Kim view a house that is for sale and he suggests they consider buying it. Kim tells Jimmy she appreciates his attempt to help her trick her client into accepting a favorable plea bargain, but does not want to succeed by lying. Jimmy turns on the Saul Goodman persona at the courthouse and avoids trials while obtaining favorable plea bargains for his clients, generating fees by producing a high case turnover. Assistant District Attorney Ericsen, who was suspicious of Jimmy when she dealt with him after Huell Babineaux's arrest, resists Saul's entreaties and insists on formally resolving their pending cases during an already-scheduled appointment. Howard invites Jimmy to lunch, and Jimmy is unsettled by the reminder of his past. Jimmy later pays a custodian, a brother of one of his clients, to disable the courthouse elevator while he is inside with Ericsen, enabling him to informally work out several favorable deals. Nacho drives up after Jimmy leaves the courthouse and coerces Jimmy into his car. The episode ties in two Easter eggs to "Breaking Bad" as the "Better Call Saul" narrative draws closer to that point, according to showrunner Peter Gould and writer Alison Tatlock. One is the origin of Domingo's "Krazy-8" nickname ("ocho loco"), which is revealed to have been given to him by Lalo during a poker game after Domingo fell for Lalo's bluff and folded on what would have been a winning set of 8s. The second is the introduction of Saul's Bluetooth headset, which he was seen wearing frequently during "Breaking Bad".  "50% Off" received critical acclaim.
