In the season finale, Walt won. With Jesse’s help, Walt managed to kill Gus by attaching a bomb to the wheelchair of Tio Salamanca. I loved Gus’s death scene. He staggers out of the room, his face half gone, and for a moment the viewer thinks maybe it is impossible to kill him, and then he falls to the floor.
Brock, Andrea’s little boy, was poisoned by lilly of the valley. Jesse tells Walt that it wasn’t Gus who killed him. He asks Walt if it was still necessary to do it. Walt says, of course. The episode and the season end with a scene of the poisonous flowers growing in Walt’s backyard. Walt has gone completely bad. There’s nothing remotely good left in him. He would do anything. In the final season, I want Jesse to kill Walt.
