On season six, episode three, Nacho (Michael Mando) submerged himself in oil inside a tanker to hide from the Salamanca twins. After coming out, he shed himself of his clothing and money before heading back to the United States.
He was given a final meal and, unlike previous episodes where he wore red to symbolize his criminal intent, wore a white shirt adorned with small crosses to show he was at peace.
On the "Better Call Saul Insider" podcast, Mando described how those actions symbolized a rebirth of the character before he took his own life in order to save his father at the episode's end.
"We were talking about how coming out of the oil tanker, he dies, he goes into hell, and then he comes out, like coming out of the womb," Mando said of the episode's symbolism. "Then he pukes, he cleans himself, and then he has no more need for anything material. He gives away all the money."
"Then, he's wearing white," Mando added of the imagery. "If you notice on the shirts, there were little crosses. If you zoom in on Nacho's shirt there were crosses."
