Jimmy McGill (Bob Odenkirk) and Mike Ehrmantraut (Jonathan Banks) will continue threading the line between good and evil in the next episode of "Better Call Saul" season 2.

In the upcoming episode titled "Cobbler," the small-time lawyer and the former police officer-turned-parking lot attendant will both attempt to make their jobs easier.

A trailer was released after the premiere episode, where Jimmy's older brother Chuck (Michael McKean) is seen asking for updates regarding his activity. When Chuck learns that Jimmy is already working with the Davis & Mane law firm, he does not seem convinced that his brother was hired there as an attorney.

At the end of the trailer, Jimmy is shocked to see Chuck out in the daylight to visit him at work, since the older McGill is suffering from electromagnetic hypersensitivity disease, which forces him to stay at home.

The trailer also reveals Jimmy's friend and possible love interest Kim Wexler (Rhea Seehorn) asking someone if he planted evidence for a case. While the trailer does not reveal who Kim is talking to, it is implied that the female lawyer is not happy with what she discovered.

Is it possible that Jimmy was the one who planted evidence since he is known for fixing things to his advantage? This could upset Kim, since the two appeared to have started something special for each other during the season premiere.

Meanwhile, Mike seems to be having problems with one of his clients. But according to the official synopsis for the episode, "Mike brokers a deal to keep a potentially messy situation from unraveling."

In a previous interview with Larry King to talk about what's in store for the second season of "Better Call Saul," McKean revealed that the season "starts dark and get's darker."

The second episode of "Better Call Saul" season 2 airs Monday, Feb. 22, on AMC.
