Chekhov's Gun Points to Murderer

Chekhov's gun is a literary technique whereby an apparently irrelevant element is introduced early in the story whose significance becomes clear later in the narrative. Well that’s what appears to be going on in Ep412 when Walt is spinning his gun. Walt spins the gun 3 times with the first two times having the gun point back at him. The third time the gun ends up pointing past Walt and into the background. Then the camera carefully shifts it’s angle to uncover that the gun is pointed at a lone potted plant. Then the camera does a close up on Walt’s face as his face shifts from defeat to where one can tell a glimmer of an idea is forming. So what appears to be an “irrelevant element” i.e. gun pointing at a plant is the birth of a desperate plan, the plant has reminded Walt of the risen ! In short Walt works out a plan to get Jesse to come to him and to get Jesse off of Gus’s side and back on his, Walt poisons Brock. And Walt know’s that will bring Jesse to him and that Jesse will be ready to do anything to revenge Brocks pending death. After all last time Jesse was ready to die for and/or kill for a child he barely knew.

Other Reasons I believe this to be true:
Starting with Season 2 Vince ends each season with Walt being responsible for a death of someone that doesn’t deserve to die and each season it’s someone that deserves it less ; Season2 was Jane, Season 3 was Gale and now … it’s Brock. Each death due to Walter.

It would just be like Vince’s twisted sense of humor to use a gun to be a “Checkhov’s gun” device !

If you listen to Ep412 behind the scene video you will hear Gus explain that he knew something was wrong in the parking lot because he hadn’t poisoned Brock. So walking back to car he deduced the poisoning was to draw him out and to the hospital ! Well if he didn’t poison Brock … who did ?

How ironic what started Walt’s entire issue with Gus was the killing of a child in Season 3 …. Now it’s come full circle and it’s going to be a killing of another child that saves him.
