Complete story — includes the ending

Walt locates Gretchen and Elliott and gives them $9,720,000 to give to Walt Jr. when he turns 18. He claims that he has hired hitmen should they fail to do so, who turn out to be Badger and Skinny Pete with laser pointers whom Walt paid to intimidate Gretchen and Elliott. Walt crashes a meeting between Lydia and Todd, putting the ricin in Lydia's stevia. He then visits Skyler and gives her the coordinates of Hank and Gomez's burial site, imploring her to use it to bargain for a plea deal, and admitting he produced meth to gratify himself. Walt drives to the Aryan Brotherhood's headquarters with the M60 machine gun which he has jury rigged in the trunk. When Jack brings Jesse in from cooking to show him to Walt, Walt tackles Jesse to the ground and triggers the M60, which mortally wounds Walt and kills everyone else except for Todd, whom Jesse strangles to death, and Jack, whom Walt shoots in the head. Jesse refuses to shoot Walt, though Walt asks him to. When Lydia calls Todd, Walt answers and informs her within earshot of Jesse about the poisoned stevia. Walt and Jesse acknowledge each other one final time before Jesse escapes in Todd's car, crying in joy. As he succumbs to his gunshot wound, Walt spends his last moments gazing around the meth lab before collapsing and dying. The police find his body in the lab moments later.
