In the vast desert, the figures of Walter and Jesse gradually moved away, escaping from the original constraints and dangers.However, the road to escape was not smooth, and Walter pondered among the endless sand dunes what to do with the car that had witnessed them countless trials and hardships.Just as he was lost in thought, Gus' car suddenly appeared in sight, bringing unknown challenges and opportunities.

Walter made a difficult decision: As long as Gus could forgive Jesse, he would continue to work for Gus.This decision was not only out of deep affection for Jesse, but also a helpless compromise for his own way of survival.He returned to the laboratory, only to find that his world was no longer his.Gus found him a new assistant, Gale, and Walter became the subject of surveillance.

The appearance of Gale made Walter feel an unprecedented crisis.He realizes that Gale is the pawn Gus uses to replace him.Once Gale masters Walter's technology, he will lose all use value and become a useless abandon in Gus's eyes.This kind of fear and uneasiness filled Walter's heart with anxiety and struggle.

However, a bigger secret is still waiting for Walter.Gus found Gale and told him that Walter made drugs because he was suffering from lung cancer and did not have much time left.Gus hopes that Gale can master Walter's skills as soon as possible so that he can take over his position in the future.This news shocked and despaired Walter, who understood that his fate was in the hands of others.

At the same time, Mike was also looking for Jesse's whereabouts.He found Jesse's address on Saul's desk, bringing hope for a reunion between the two.However, the joy of reunion was quickly diluted by the cruelty of reality.Walt tells Jesse that he has decided to wash his car to launder money, and Jesse proposes that the two of them escape this dangerous world together.But Walter is unwilling to abandon his family. He is well aware of his responsibilities and ties.

On the verge of life and death, Walter made a more radical decision.He realized that only by killing Gale would he have a chance to survive.He hoped that Jesse could help him complete this task, but Jesse refused.Walter had no choice but to order Jesse to follow Gale, get his home address, and then go and deal with the threat himself.

However, just when Walter was about to take action, Gus's men suddenly appeared at his door and took him away.Walter knew that his plan had been discovered by Gus.At the critical moment of life and death, he tried to use Jesse in exchange to save his own life.But in the process of calling Jesse, he took the opportunity to ask Jesse to kill Gale.
