I had him out to my house. Fourth of July. We cooked out in the backyard. My son shucked the corn. My daughter cut up potatoes. Fring brought sea bass. Every time I grill it now, I make a little foil pouch, just like he showed me. That whole night, we were laughing, telling stories, drinking wine. And he's somebody else completely. Right in front of me. Right under my nose.
|― Merkert to Hank and Gomez about his friendship with Gus Fring.|
Because of his close personal friendship with Gustavo Fring and Fring's history as a generous philanthropist and public booster for the DEA, he was skeptical of Hank's notion that Fring might be involved with the criminal drug trade. After Hank's theories were revealed to be true by the discovery of Gus' Drug Empire and Gus' kingpin status, George Merkert lost his job.
Merkert became ASAC of the DEA Albuquerque at some point in his life. He has a wife named Kathy and a son and daughter. He was good friends with Gustavo Fring and once even had him over to his home for the Fourth of July. Merkert was completely unaware that Fring was one of the most powerful meth distributors in the Southwest and was operating right under his nose.
When Hank returns, Merkert is frustrated by Hank's stalling on a second transfer to El Paso, unaware that Hank is suffering from panic attacks and is scared to go back. After Hank attacks Jesse Pinkman, Merkert is forced to suspend Hank without pay, but tells him off the record that Jesse won't press charges and that Hank must have a "guardian angel". ("") Notably, this leaves Hank without his gun.
Merkert listens to Hank's suspicions that Gustavo Fring might be the meth kingpin they've been looking for all along. Merkert, Gomez, Hank, and Tim Roberts interview Gus in relation to the death of Gale Boetticher; however, all but Hank fall in with Merkert and believe that Gus is telling the truth. Merkert in particular is insistent that Gus is an honest man and a long-time friend of the DEA.
In the last episode of Season 4, he also appears at the meeting between Hank and Hector Salamanca.
Early in the fifth season, it is revealed that Merkert has been forced out as head of the DEA because of his personal friendship with Gus and his failure to identify him as a drug lord. Merkert is visibly upset by his failure to have never realized who Fring really was and not listening to Hank and tells a heartbreaking story to Hank and Gomez of how he considered him a friend and invited him out to his home, all the while having a drug kingpin right under his nose. This story is ironic as Hank's own brother-in-law, Walt, is also a drug kingpin and operating under his own nose (he is in an even worse spot than Merkert). ("")
