Breaking Bad/Fridge

Fridge Brilliance

 * Some episode titles have double or hidden meanings.
 * The titles of the final Season 2 episodes "737", "Down", "Over" and "ABQ" hint at the events in the season finale.
 * The season 4 finale "Face Off" has, of course, two meanings by the end.
 * a more thematic example - "Face Off" appears to bring the series full circle, with the death of Gus finally freeing Walter from the cycle of danger he's been in for the past four seasons - the green shirt adding a symbolic touch to this notion - though of course, he is a vastly changed man. The first episode we meet Gus is "Mandala" - which is Sanskrit for "circle".
 * Walt's strange overreaction to the cash register sound his son's computer is giving off. It is the exact same sound of Tuco's uncle ringing his bell.
