Major theme from breaking bad has been walt's ego especially when he's not getting the respect he feels is due from his talent. Gray Matter interview touched that nerve and to add insult to injury he heard the Heisenberg blue was back on the streets. He knows only Jessie has the ability to make his brand so firstly the nazi's disrespected and lied to him by not killing Jesse and secondly their stealing his brand. Todd, gray matter, Lydia and Uncle Jack are all eating off him and his wife driving a taxi! Heisenberg won't take that lying down
The emphasis on Splenda suggests to me that Lydia will mysteriously put ricin in her coffee.
Todd is always polite...yes sir but ruthless.
The writers of this show show open contempt for Hispanic people they get killed brutally
