It happens at the start of the episode. A group of people, including two vicious hitmen (relatives of the deceased psychotic meth dealer Tuco Salamanca), crawl to the shrine. Inside is a skeleton dressed something like a Catholic saint. I have read that the Santa Muerte cult is popular among criminals in Mexico. There are many saints in churches throughout Mexico. I have seen the Santo Nino de Atocha image in Fresnillo, Zacatecas, Mexico the Santo Nino de Atocha image in Fresnillo, Zacatecas, Mexico, which is almost the opposite of Santa Muerte. The worshipers I saw did not crawl to approach this saint, but scurried on their knees . Locals believe that Santo Nino has the power to make peace among people. I can't think of any other TV show which has anything like this!
