when does walt say i am the one who knocks
Cornered (Breaking Bad) Skyler (Anna Gunn) realizes that Walter's (Bryan Cranston) voicemail he left earlier declaring his love for her and the family was actually meant to be a last message to them. She suspects Gale's death is related to the meth operation, which leads her to pressure Walt to call the police due to the danger it presents their family. She suggests a hypothetical situation where one day an in-over-his-head Walter opens his front door and is shot in the face; Walter, furious that she does not understand the scope of his criminal operation, responds that, in that scenario, he'd be "the one who knocks." The level of apparent danger causes Skyler to flee the house, taking Holly with her. She ponders escaping to Colorado, going so far as to drive to the Four Corners Monument, but ultimately reconsiders.
