"ABQ" is the thirteenth and final episode of the second season of the American television crime drama series Breaking Bad.

Walt calls Saul Goodman, who sends a cleaner, Mike Ehrmantraut, to remove evidence of drugs from Jesse's apartment.

On the day of Walt's operation, as he is put under anesthetics, he groggily reveals the existence of a second cell phone he uses, making Skyler White suspicious of his activities.

When Walt is released from the hospital, Skyler reveals that she has investigated his behavior over the past several months and found he has lied to her many times.

The plane crash at the end of the episode was inspired by Aeroméxico Flight 498 back in 1986 (as referenced above), in which the air-traffic controller who was directing air traffic at the time of the real-life accident shares the name of the lead character of Breaking Bad, Walter White.

[2] The role of the cleaner to help Jesse prepare to deal with the police was originally meant to be handled by Saul Goodman, played by Bob Odenkirk.
