Better Call Saul
Barry is tasked by Gus to pick up Mike who passed out after getting beaten up and stabbed by a group of thugs. He takes him to Mexico and tends to his wounds. Mike tries to leave immediately after waking up but Barry finds him and advises him to stay until he's all healed up as he would "not survive the journey" back home in his current state. ("")
Barry and his team treat Gus for poisoning and Mike for gunshot wounds after they led an attack on Don Eladio and the Juárez Cartel. He initially ignores Mike and goes straight to helping Gus, because Gus "pays his salary". It is known that he has blood samples and knows the complete medical history of Gus, Mike, Jesse, and most likely others. ("")
- Barry is one of the survivors of Gus' network, likely because Walter and Lydia never crossed paths with him.
- It's unknown why he has the same last name as the the invented name "Saul Goodman"
