She is also a single mother, raising a young daughter named Kiira Rodarte-Quayle. He insists to Walt and Jesse that she needs to be killed, until they discover that the DEA secretly planted tracking devices on every methylamine barrel in the Madrigal warehouse.
Since her supply is now compromised, Lydia tries to regain her value before the guys decide to kill her anyway. She tells Walt about a train carrying a huge amount of methylamine through New Mexico, and helps them plan the perfect robbery.
Lydia is a long-time employee of the German manufacturing and shipping conglomerate Madrigal Electromotive GmbH , operating out of their office in Houston, Texas. However, it appears that Lydia's partner or husband left the both of them, leaving Lydia to raise her daughter alone. At some point she became a partner to Gustavo Fring and Peter Schuler in their secret meth operation, assisting Gus in his distribution network and helping him procure necessary chemicals, equipment, and resources to aid in his expanding empire.
Lydia and Gus in Gus told her that "it could work," in reference to its suitability as a site for what would become the superlab. She explained to him the process of laundering his money, giving him the phony job title "logistic consultant," which exists as merely a paper transaction in order to give him legal means of transferring his illegally obtained money into a bank account. She also corrects Mike on how he doesn't really know Gus in assuming he is "just a drug dealer".
Lydia calls Gus to complain about Mike. Lydia summons Mike to ask him to stop testing the security of the Madrigal facilities after he swipes a security badge. Mike refuses, asserting that publicly performing his duties as Madrigal's security consultant reinforces his cover story. Finding herself at an impasse with Mike, Lydia warns him that he still has Gus's respect and advises him not to lose it.
