Lydia Rodarte-QuaylePlayed by Laura Fraser
The Head of Logistics at Madrigal Electromotive's outpost in Texas, Lydia was Gus Fring's methylamine supplier. After Gus' death, Lydia asks Mike to eliminate any loose ends that might connect her to the world of organized crime. When Mike refuses, she hires someone else to kill Mike and Gus' other associates. Mike outmaneuvers the hitman, and nearly kills Lydia for her deception. At the last minute, he offers clemency on the condition that she supplies methylamine to Walt's new meth operation.
When a GPS tracking device is discovered on the barrel of methylamine that Lydia planned to give Jesse, Mike suspects Lydia is working with the DEA. 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.
After Walt kills Mike, he obtains the names of Gus' imprisoned associates from Lydia and has them killed. Knowing that she's next on the chopping block, Lydia finds another way to become invaluable to Walt: she becomes his business partner, expanding his meth empire to Europe. Business thrives for months… until Walt decides to quit.
