Gus Fring (Giancarlo Esposito) finally made his debut in “Better Call Saul” Season 3, episode 2 and it reminded us that he is one smart cookie. The AMC series began right where it left off with Mike (Jonathan Banks) following the tracking device that was discreetly inserted in the gas cap of his car.

Gus Makes His Entrance

Mike spends much of his time in “Witness” continuing to track the device and find the person who seems to know about his illegal life. The man with the tracking device goes to multiple places and eventually lands in a restaurant selling fried chicken with salsa on the side. Yes, this restaurant is none other than Los Pollos Hermanos, the fast-food chain of dine-ins that were a front for Gus’ money laundering.

Of course, Mike can’t go to the restaurant. He’s the one being tracked. So, instead, he calls his good old friend, Jimmy McGill (Bob Odenkirk), to find out what this tracking guy does with the device. Does he give it to someone in the restaurant?

Jimmy clears his morning schedule and comments on his James Bond-type devices before entering Los Pollos Hermanos. He orders food and waits for the man to turn up. Finally, the man with the device in his brown bag enters and orders his food. Jimmy diligently keeps an eye on him and even changes his table to get a better view.

While Jimmy is spying on the man, unbeknownst to him, Gus is casually sweeping and cleaning the floor. He even sweeps this man’s table. Then the tracking device guy finishes up his food and throws the trash in the garbage.

Jimmy immediately goes to the garbage bin to see if he left anything in there. However, Gus, in manager mode, is swiftly by his side and asks him if he needs help. Odenkirk’s character mumbles something about losing his watch and Gus promptly finds it and gives it back.

The tracking device guy didn’t meet anyone or drop anything. Mike is disappointed when Jimmy relays this information to him. But Mike isn’t a quitter.

Mike continues to stake out the restaurant before seeing Victor (Jeremiah Bitsui). He follows him to a deserted road. Gus ordered someone to put the device in the middle of the road with a cellphone on top. Mike reaches for the phone and says, “Hello?” Is that Gus on the other end?

Jimmy Gets Into More Trouble

Apparently, Chuck (Michael McKean), Jimmy’s older brother, wanted Ernesto (Brandon K. Hampton) to hear the recorded confession. Just like he predicted, Ernie told Jimmy’s girlfriend Kim (Rhea Seehorn) who then told Jimmy about the taped confession.

Kim asks Jimmy to give her a dollar and becomes her lawyer. Now he can tell her everything and they are protected with the confidentiality agreement. Kim tries to find legal loopholes that ensure they can’t get into any legal troubles due to the tape. While Jimmy is grateful, he is distraught at learning that his brother conned him.

Even worse, his sadness turns into anger and he enters Chuck’s apartment by breaking the door. Once inside, he smashes the tape and threatens his sibling. Unbeknownst to him, Howard (Patrick Fabian) and a private detective are hiding in the living room and have witnessed the whole scene. Now, Chuck has witnesses who saw Jimmy threaten his brother and destroy evidence that implicated him in a crime. Oh no.

While all this was taking place, another “Breaking Bad” character was introduced in “Better Call Saul” Season 3, episode 2. Remember Saul’s secretary Francesca (Tina Parker)? In “Witness,” she got hired by Jimmy and Kim to become the secretary of their law firm. Jimmy even trains her on how to answer phone calls.

“Better Call Saul” airs Mondays at 10 p.m. EDT on AMC.
