Hermanos (Breaking Bad)

In the present, Gus meets with the police and DEA and is told that his fingerprints were found at the scene of a homicide.

Hank asks Walter to drive him to a mineral show, but reveals en route that he is really going to Los Pollos Hermanos to plant a GPS tracker on Gus's car.

Hector shoots Max through the head and forces Gus to look him in the eyes as he bleeds into Eladio's swimming pool.

Series creator Vince Gilligan has said Gus was likely involved in the military dictatorship of General Augusto Pinochet, but the writing staff had deliberately not determined the entire backstory.

Gilligan said he believed this would make Gus a more interesting and mysterious character, while simultaneously allowing the writers greater flexibility in writing for him in future episodes.

[1] Alan Sepinwall of HitFix praised the episode, describing it as "another superb hour of season 4".
