Henry R. As a DEA agent, Hank lead the investigations of the methamphetamine cook "Heisenberg" unaware for over a year that he was actually his own brother-in-law , as well as Gustavo Fring and his drug empire. Hank is faced with numerous threats from the rival drug cartels which take a toll on his mental health, causing him to develop post traumatic stress disorder PTSD. Despite his brashness, Hank is highly competent at his job and cares deeply about his family.
After a drug deal goes bad, Walt and Jesse are kidnapped by the unstable Tuco Salamanca and taken to a remote abode with his uncle, retired drug cartel boss Hector Salamanca. Hank helps with efforts to find Walt, and traces him via Jesse to Tuco's abode. Just before Hank arrives, Walt and Jesse manage to escape, wounding Tuco in the process. Hank kills Tuco in a shootout and arrests Hector. Meanwhile, Walt and Jesse flee back to Albuquerque, where Walt explains his disappearance to Skyler as the result of a fugue state.
Hank questions Hector on the blue meth and Heisenberg, but Hector refuses to answer. Hank also questions Jesse, but Jesse provides no conclusive statements to provide leads to Heisenberg. Though initially happy, Hank quickly realises he doesn't fit in with his Spanish speaking colleagues and also starts having panic attacks.
Hank develops symptoms of PTSD and transfers back to the Albuquerque office to continue his investigation into the blue meth. Some time later, Hank receives an anonymous call from Gustavo Fring , warning him that he is about to be killed by Leonel and Marco Salamanca in revenge for killing Tuco.
Hank is able to kill one brother and mortally wound the other, but he himself becomes temporarily paralyzed. Hank struggles through his recovery due to his helplessness, and tries to collect minerals to pass the time. His interest is piqued when the Albuquerque Police Department ask him to help with looking over evidence from the murder of Gale Boetticher , who had been Walt's lab assistant at Gus' meth superlab under an industrial laundry.
