13 Most Shocking Breaking Bad Moments

It's the show's best speech; the moment that perfectly captures just how far Walt has come and the moment that Skyler finally realises just how much her husband has changed.

"Cornered", the sixth entry of Season Four, sees Skyler sure that Walt is in over his head and that one day he's going to end up dead because of his actions. Appalled by his wife's dismissal of his power and assurance that he is not strong as he thinks he is, Walt shuts her down with an eloquent and cold speech in which he states: "I am not in danger, I am the danger."

This causes Skyler to fall into stunned silence and after he has left she flees with their daughter, Holly, and ponders driving far away where Walt can't get to them.

It's a brilliantly acted scene, with Bryan Cranston and Anna Gunn both working off one another perfectly, and Walt's assertion that he is the man people should fear is a stand-out moment in his final descent into villainy.
